BACKGROUND
The working group was set up in response to the increasing number of patients with a
tracheostomy who were being cared for in general wards throughout the Trust by staff who
had little knowledge and experience in this area of practice. An increasing number of
enquiries to specialist areas seeking advice on tracheostomy care demonstrated this gap in
knowledge.
An audit of the nursing care of patients with a tracheostomy was carried out in the wards at
Aberdeen Royal Infirmary in August 2001. The results of the audit showed that although
basic care was good, the depth of knowledge and understanding required to ensure a safe
pathway of care from surgery to tube removal was lacking. (1)
The development of this guideline reflects the current emphasis on safe effective care and
will reduce existing variations in practice. Implementation will promote best practice
wherever patients receive care.

INTRODUCTION
Care of the tracheostomy patient "takes insight into the physiological changes caused by the
tracheostomy tube, careful monitoring to prevent complications, meticulous wound care and
expert suction technique". (2)
The guideline has been drawn up by a multidisciplinary group using evidence where it exists
and best practice standards. It is intended for use by all NHS Grampian healthcare
professionals involved in the care of adults with a tracheostomy.
The guideline is general and will apply in the majority of cases throughout the various areas
of care.
It is recognised that in some specialist areas eg Ear Nose and Throat (ENT) there may be
the need for clinical staff and management to discuss and decide the need for local specific
arrangements to be derived and implemented.
Significant departures from the guideline should be fully documented and the reasons for the
differences explained.
The guideline is not intended to be construed or to serve as a standard of care. Standards
of care are determined on the basis of all clinical data available for an individual case and
are subject to change as scientific knowledge and technology advance and patterns of care
evolve.
Trust guidelines on consent must be followed.
We wish to acknowledge reference to St George's Healthcare NHS Trust "Guidelines for the
Care of Patients with Tracheostomy Tubes" in some sections of this document.

DEFINITION OF A TRACHEOSTOMY
A tracheostomy is a surgical incision into the trachea through the neck. A tracheostomy tube
is inserted into this providing a patent opening. The tube enables air flow to enter the
trachea and lungs directly, bypassing the nose, pharynx and larynx.
Figure 1:
Diagram of larynx and trachea illustrating the sites of the
tracheostomy tube inserted
INDICATIONS FOR TRACHEOSTOMY

To secure and clear the airway in upper respiratory tract obstruction.

To facilitate the removal of bronchial secretions.

To facilitate weaning from artificial ventilation in acute respiratory failure and prolonged
ventilation.

To protect the airway of patients who are at high risk of aspiration eg neuromuscular
disorders, unconsciousness.

To secure and maintain a safe airway in patients with injuries to the face, head or neck
and following surgery to the head and neck.
PHYSIOLOGICAL CHANGES




The upper airway anatomical dead space can be reduced by up to 50%. (3)
The patient's ability to speak is removed.
The ability to swallow is adversely affected.
The warming, humidification and filtering of air that usually takes place in the upper
airway is lost. (4)

TECHNIQUES OF TRACHEOSTOMY
Open Tracheostomy
Most surgeons prefer to perform standard elective tracheostomy in an operating room where
sterility is more easily maintained and specialised lighting is readily available. Most also
prefer to use general anaesthesia, although local anaesthesia is sometimes used. The
patient is positioned supine, usually with a roll beneath the shoulders to extend the neck.
After the anterior neck has been cleaned and painted with antiseptic, a 4 cm transverse
incision is made over the second, third, or fourth tracheal ring. The subcutaneous tissues
are divided and the anterior neck muscles and vessels are retracted. If the thyroid isthmus
overlies the region selected for tracheostomy, it is ligated and transected. After the trachea
has been exposed, one or more cartilages are incised to create an opening into which to
place the tube. In some cases, a plug of cartilage is excised from one or more rings. The
tracheostomy tube is inserted into the opening and the incision is closed with sutures or
staples. Some surgeons elect to suture the flanges of the tube to the skin, whereas others
are content to secure the tube with cloth ties. Some techniques form a flap of tracheal wall
that has sutures placed in it that are brought to the surface out through the stoma. If the
tube is displaced these can be used to re-open the hole for re-cannulation.
Percutaneous Dilatational Tracheostomy
The most commonly used method involves the insertion of a needle through the neck into
the trachea, followed by passage of a guide-wire through the needle. The needle is
removed and its tract gradually enlarged by inserting a series of progressively larger dilators
over the wire. After a sufficiently large opening has been created, a tracheostomy tube is
inserted. Bronchoscopic guidance is often used to ensure proper tube placement and
promote safety. The percutaneous technique is attractive because of its simplicity and
speed. Furthermore, percutaneous tracheostomy can be safely performed under local
anaesthesia at the bedside in the intensive care unit, obviating the sometimes precarious
exercise of transporting the critically ill patient to and from the operating room. Current
evidence suggests that percutaneous and surgical tracheostomies are equally safe
procedures. It is increasingly considered the technique of choice in critically ill patients. (5)

8
Mini Tracheostomy
Mini tracheostomy is the insertion of a small 4 mm non-cuffed tracheostomy tube through the
cricothyroid membrane. This can be done under local anaesthesia. It is primarily inserted to
facilitate the removal of secretions. It does not protect the airway from aspiration and will
only provide a route for oxygenation in the emergency situation.

Mini Tracheostomy

COMPLICATIONS OF A TRACHEOSTOMY
"Historically, tracheostomy was associated with a high risk of complications and a significant
mortality rate. The reported complication rates in adults undergoing tracheostomy vary
considerably but it is generally held that complications are more frequent after emergency
tracheostomy for airway obstruction." (6)
1. Immediate




Haemorrhage (minor or severe).
Misplacement - pretracheal tissues or to main bronchus. (7)
Pneumothorax.
Occlusion of the tube by cuff herniation.
2. Delayed







Tube blockage with secretions. May be sudden or gradual. Rare with adequate
hydration, humidification and suction.
Infection of the stoma site.
Infection of the bronchial tree.
Distension of the trachea with an overinflated cuff leading to ulceration, necrosis.
Mucosal ulceration due to asymmetrical inflation of the cuff, excessive cuff pressures
or tube migration (due to loose tapes or patient intervention).
Risk of occlusion of the tracheostomy tube in obese or fatigued patients who have
difficulty extending their neck.
Tracheo-oesophageal fistula formation.
3. Late





Granulomata of the trachea may cause respiratory difficulty when the tracheostomy
tube is removed.
Persistent sinus at the tracheostomy site.
Tracheal dilation.
Tracheal stenosis at the cuff site.
Scar formation requiring revision.
10
TYPES OF TRACHEOSTOMY TUBE
A variety of tracheostomy tubes are available and tube selection is dependent on the
patient's specific needs.
Tracheostomy tubes vary in size, composition, number of parts and shape.
Single Cannula Tubes
Single cannula tubes are usually the first tube to be sited. The system is less complicated
than double cannulation and is usually for temporary use only.
Double Cannula Tubes
Double cannula tubes have an outer cannula to keep the airway open and an inner cannula
which acts as a removable liner to facilitate cleaning of impacted secretions. Some inner
cannulae are disposable, others must be cleaned and re-inserted.
Cuffed Tubes
Cuffed tubes have a soft balloon around the distal end of the tube which inflates to seal the
airway. Cuffed tubes are necessary when positive pressure ventilation is required or in
situations where airway protection is essential to minimise aspiration of oral or gastric
secretions

Oral feeding should not be commenced with an inflated cuff because an inflated cuff can
anchor the larynx and reduce laryngeal elevation. It also prevents pulmonary air from
clearing the larynx during swallowing. If a patient is aspirating it is vital to know
immediately so suctioning can be carried out and management planned.

Cuff pressures should be checked regularly with a cuff manometer because excessive
pressure (>30 cmH2O) may result in tracheal-mucosal damage including capillary
occlusion, tissue necrosis and stenosis. Refer to page 14 (Checking Cuff Pressures).
If the tracheostomy tube lumen is occluded when the cuff is inflated, the patient will not be
able to breathe. In this situation, it is important to deflate the cuff and call for medical
assistance immediately (refer to Emergency Algorithm Appendix III).
Uncuffed Tubes
Uncuffed tubes do not have a cuff that can be inflated inside the trachea and tend to be
used in longer-term patients who require ongoing suction to clear secretions. It is essential
that patients have an effective cough and gag reflex to protect themselves from aspiration.
Cuffless tubes are rarely used in acute care and are not suitable for patients receiving
positive pressure ventilation.

Figure 5:
Single cannula, cuffed tracheostomy

12
Fenestrated Tubes
Fenestrated tubes have an opening(s) on the outer cannula, which allows airflow to pass
through the patient's oral/nasal pharynx as well as the tracheal opening. The air movement
allows the patient to speak and produces a more effective cough.
However, the fenestrations increase the risk of oral or gastric contents entering the lungs. It
is therefore essential that patients who are at high risk of aspiration or on positive pressure
ventilation do not have a fenestrated tube unless a non-fenestrated inner cannula is used to
block off the fenestrations. Suctioning with a fenestrated tube should only be performed with
the non-fenestrated inner cannula in situ, to ensure correct guidance of the suction catheter
into the trachea.
Note: Additional information on specialised tracheostomy tubes should be sought from
senior nursing and medical staff on ENT/Maxillo Facial Surgery or the Speech and
Language Therapy Department.

CARE OF PATIENTS WITH A TRACHEOSTOMY
There should be a detailed plan of care for all patients with a tracheostomy. This should be
reviewed on a daily basis and updated if there is any change.
The patient with a tracheostomy needs diligent observation and assessment. The nurse
caring for the patient is responsible for this seeking advice from other professionals as
appropriate.
PATIENT ASSESSMENT
Patient assessment should include:






Type and size of tracheostomy tube
Respiratory rate, pattern and skin colour
Oxygen saturations – if indicated
Amount and consistency of secretions
Oxygen percentage
Checking cuff pressure
This should be documented on the Suction Sheet (Appendix I).
ESSENTIAL EQUIPMENT
When caring for a patient with a tracheostomy there are several essential pieces of
equipment that should always be at the bedside.










2 tracheostomy tubes
-
one same size
one size smaller
10ml syringe for inflating/deflating cuff
1 pair tracheal dilators
Oxygen supply and humidification
Suction equipment
Disposable gloves (both clean and sterile)
Stethoscope
Ambubag with catheter mount should be available on resuscitation trolley.
Pulse oximeter (if indicated)
Cuff manometer - there should be one available per ward.
This equipment should be checked at the beginning of each shift and all but the cuff
manometer should accompany the patient if they are being transferred to another area.
CHECKING CUFF PRESSURE
Each ward area caring for patients with tracheostomies should have a hand held cuff
manometer available. The manometer should only be used to measure cuff pressure, not
to inflate or deflate the cuff.
It is recommended that cuff pressure should be measured every shift by using a hand
pressure manometer and recorded in the suction sheet. This will indicate the pressure
exerted by the cuff on the tracheal wall.
14
The cuff inflation pressure should range from 1530 cmH2O. Pressure exerted on to the
tracheal wall greater than 30 cmH2O may result in capillary occlusion, tissue necrosis and
tracheal stenosis(8). If the pressure is greater than 30 cmH2O and an air leak is still present 
seek medical advice as the tube may require to be upsized.
Figure 7:
Cuff Manometer
Caution
Estimation of cuff pressure by fingertip pressure on the external pilot balloon or filling until no
air leak is heard is an inaccurate measure of this pressure and puts unnecessary extra
pressure on the tracheal wall.
Complications of Unsatisfactory Cuff Pressure

Cuff pressure too high
- tracheal wall weakening
- tracheal necrosis

Cuff pressure too low
- Increased risk of aspiration
- Unable to achieve optimal positive pressure ventilation

Action



Rationale
Perform
synchronised
suction/cuff
deflation technique as follows:

Simultaneous suction should enable
secretions to be caught and removed as
they pass the gradually deflating cuff.
 Pass a sterile suction catheter into
the tracheostomy tube approximately
0.5 cm longer than the tracheostomy
tube tip.

Minimise the risk of cross infection and
trauma.
Simultaneously the second practitioner
should remove air in 0.5 ml increments
from the tracheostomy cuff until fully
deflated using a 10 ml syringe. The
whole procedure should take no longer
than 15 seconds and the patient should
be encouraged to cough.

Gradual deflation assists the patient to
adjust to changes in airflow and allows the
patient to adapt to the feeling of being able
to breathe through their nose and mouth
again. (12)

Coughing reduces the risk of aspiration.
Observe patient for signs of respiratory
distress.

The patient is at risk of aspiration. These
signs will provide early indication that the
patient is unable to maintain their own
airway. (9)


Observe spontaneous swallow and the
patient's ability to manage oral
secretions.

Indications for Cuff Inflation

Signs of respiratory distress
*Re-inflate tracheostomy cuff immediately*

Trial deflation complete.
Action
Rationale

Inflate the cuff using a 10 ml syringe
inserting the air gradually in 0.5 ml
increments until the balloon is inflated.

Assess cuff pressure using a manometer
(cuff inflation should not exceed 30
cmH2O) and adjust as required using the
syringe.

Reassess and observe the patient.

TRACHEOBRONCHIAL SUCTION
Indications

Presence of retained secretions which are detrimental to the patient as indicated by:






visible secretions in the airway.
increased work of breathing
coarse crackles on auscultation, or 'noisy' breathing
suspected aspiration of gastric or upper airway secretions
deterioration of arterial blood gases
radiological changes consistent with retention of pulmonary secretions eg
atelectasis/consolidation
 increased peak inspiratory pressures or decreased tidal volume during ventilation

Inability to clear retained pulmonary secretions due to ineffective spontaneous cough.

To maintain the patency and integrity of the airway.
Equipment
Ensure an adequate supply of equipment at the bedside

Vacuum source

Calibrated, adjustable regulator set at 150-170 mmHg/20-23kPa (14)

Collection bottle and connecting tubing


 size 14 FG = size 9 tracheostomy
 size 12 FG = size 8 tracheostomy
 size 10 FG = Mini tracheostomy (15)

Correct catheter design (eg catheters with a rounded tip and multiple eyes cause less
invagination of the mucosa - 'Gentle-flo'). (13)

Bowl containing water

Sterile saline (NaCl 0.9%) - if instillation is desirable.

Goggles, mask and other appropriate equipment if necessary for universal precautions.


Action
Rationale
1. Assess patient and determine whether
suction is indicated and appropriate.
To ensure stability of patient's medical
status and rule out any contraindications to treatment.
2. Wash hands and put on disposable plastic
apron, gloves and goggles.
To reduce risk of cross-infection.
3. Explain the procedure to the patient
To gain verbal consent, co-operation,
confidence and to re-assure.
4. Position patient appropriately.
To ensure head is in mid-position to
prevent deviation of the tube.
20
5. Consider
pre-oxygenation
for
>30
seconds prior to the suctioning event.
To maintain adequate arterial oxygen
levels and to reduce the risk of
arrhythmia and hypoxia. (18)
A 'closed suction system' may be used
to
facilitate
oxygenation
during
suctioning.
6. COPD patients should be assessed to
ascertain the need for hyperoxygenation.
COPD patients may have an altered
carbon dioxide response mechanism
and therefore should not routinely be
given 100% oxygen. (19)
7. Ensure suction unit is functioning and set
to suggested vacuum pressure of
150-170mmHg/20-23 kPa. (12)
Experimental data to support an
appropriate maximum suction pressure
is lacking.
However high negative
pressure can cause mucosal trauma,
subsequently increasing the risk of
infection and atelectasis. Meanwhile,
low pressures are ineffective at clearing
sputum.
8. Peel the outer sheath of an appropriate
suction catheter (considering size and
design) to reveal the suction control port
and connect the catheter to the suction
tubing. A sputum trap may be connected
at this stage if a specimen of sputum is
required.
9. Place a sterile glove on your dominant
hand and gently remove the catheter
sheath with your non-dominant hand,
controlling the sterile catheter with your
sterile hand.
Take care not to
contaminate the catheter once it has been
removed from the sheath. (20)
To reduce the risk of cross-infection and
ensure the technique is as 'clean' as
possible.
10. Consider installation of 1-3mls of normal
saline via the tracheostomy, prior to the
suctioning procedure. The saline should
be administered during the patient's
inspiratory phase.
(Discuss with
physiotherapist or medical staff prior
to utilisation.)
The value of saline is questionable.
However, it may be beneficial in
initiating a cough reflex, which aids the
removal of secretions.(21) It should not
be routine practice as it may reduce
baseline saturation levels, induce
bronchospasm or increase bacterial
colonisation. (22)
21
11. Gently, without suction, introduce the
catheter into the patient's airway until a
'hard-end feel' or resistance is reached.
At this stage the catheter will probably be
on the 'carina' and a cough may be
stimulated. Withdraw the catheter slightly,
then apply suction, gently removing the
catheter in one continuous movement.(23)
Rotation is not necessary and the
duration of the suction procedure should
not exceed 15 seconds. (24)
Resistance on passing the catheter
probably indicates that the inner tube of
the tracheostomy is crusted with
secretions. It will therefore need to be
changed or cleaned.
12. Reapply the patient's oxygen supply
immediately by replacing the catheter
mount/tracheostomy mask.
To reduce the risk of further hypoxia
and restore arterial oxygen levels as
quickly as possible.
13. Dispose of catheter and gloves in clinical
waste (orange) bag.
14. Monitor patient throughout the procedure
and modify treatment as appropriate.
Assess for signs of distress and/or
variation in haemodynamic, ventilatory
or neurological parameters.
15. Repeat procedure as often as required.
This will depend on the clinician's
assessment,
individual
patient's
condition and response. Continual reassessment of the patient's status is
essential.
16. On completion flush the suction tubing
with tap water, leaving the bowl dry.
Turn off suction pressure and wash hands
at end of procedure. Tidy bedspace
ensuring patient comfort.
To reduce risk of cross-infection and
suction tube blockage
22
To ensure patient comfortable/stable.
CLOSED SYSTEM MULTIPLE USE SUCTION UNITS (CSMUSU)
Figure 8:
Closed System Multiple Use Suction Unit (CSMUSU)
Indications
1. A patient who requires a high FiO2/PEEP where disconnection results in a drop in
oxygen saturation and tissue hypoxia. (25)
2. A patient with copious/infected secretions. (26)
See Action/Rationale numbers 1-7 on pages 20-21.
Action
Rationale
1. Unlock the suction application port.
2. If installation of saline is desirable
following
consultation
with
the
Physiotherapist or Medical Staff (to
stimulate a cough reflex) attach syringe
or prefilled saline ampule to installation
port and pass the tip of the catheter until
the black marking is visible in the Tpiece.
23
Normal saline 0.9% will naturally follow the
tip of the catheter ensuring delivery of fluid
into the lower airways (pooling of saline in
the T-piece can otherwise occur).
The
introduction of normal saline (0.9%) may aid
secretion removal by stimulating a cough
reflex.(21)
However, it should not be
routine practice as it may reduce baseline
saturation levels, induce bronchospasm
or increase bacterial colonisation.(22)
3. Introduce the catheter into the trachea,
withholding the outer plastic sheath.
Take care not to bunch the outer plastic
sheath in front of your hand but pass it
behind
your
hand
with
each
advancement.
The outer plastic sheath allows repeated reuse protecting the catheter from external
pathogens and reducing the need for the
user to wear sterile gloves. Bunching of the
outer sheath at the distal end of the catheter
may reduce the 'feel' that the operator gets
from the catheter.

HAZARDS/COMPLICATIONS OF SUCTIONING
1. Hypoxia/Hypoxaemia (28)




Removal of oxygen
Temporary atelectasis
Reflex bronchospasm
Interruption of ventilation/respiration.
Hypoxaemia can be minimised by:





Limiting the procedure time to 10-15 seconds.
Pre-oxygenation.
Correct catheter size and negative pressure.
Maintain a closed system for patients requiring a high FiO2.
Appropriate frequency of suctioning.
2. Tissue trauma to tracheal and/or bronchial mucosa (23)
This can be modified by:



Correct suction pressure.
Good technique for insertion and withdrawal.
Correct catheter design.
3. Cardiac Arrhythmia's/Bradycardia/Arrest: (28)
Causation Mechanism:




Irritation of respiratory tract.
Vaso-vagal reflex response.
Narrowing of coronary arteries and alternation in conductivity.
Arrhythmias, Bradycardia and Asystole.
Cardiac Arrhythmias etc may be minimised by:



Pre-oxygenation.
Careful patient selection with regards to timing and necessity of suctioning.
Good technique.
(Note:
If concerned regarding vagal stimulation and suctioning is essential ensure atropine available.)
25
4. Infection (patient or clinician) (29)
This can be minimised by:



Sterile fresh catheter for each application
Sterile technique at all times
Goggles and mask.
5. Raised ICP (30)

Increased ICP may occur because arterial carbon dioxide levels increase during
suctioning causing cerebral vasodilation. The degree of hypoxia and impairment of
venous outflow from coughing may also affect the ICP.

To minimise this, suctioning should be carried out sparingly, and contact with the
carina should be avoided.
6. Pulmonary Atelectasis (31)

Due to removal of air, dynamic compression, airway closure and interruption of
ventilation/respiration.
7. Bronchospasm/Laryngospasm (32)
8. Patient Anxiety
Other Considerations:





Stridor
Pulmonary oedema
Tracheo/oesphageal fistula
Clotting Disorders
Hypotension/Hypertension
26
OXYGEN THERAPY
Oxygen Therapy is the administration of oxygen at concentrations greater than that in
ambient air with the intent of treating or preventing the symptoms and manifestations of
hypoxia. (33)
Note: Oxygen is a fire hazard.
Indications for Instituting Oxygen Therapy

Post-operatively as prescribed by the anaesthetist.

Hypoxaemia where PaO2/SpO2 are below desirable range for specific clinical situation

Cardiovascular instability including hypotension, tachycardia, myocardial ischaemia or
myocardial infarction

Critically ill patients

Acute head injury

Cardiac or respiratory arrest

Carbon monoxide poisoning
Note: Some non-specific clinical features of hypoxia may include:



Altered mental state
Cyanosis
Arrhythmias.
Complications of Oxygen Therapy

Discomfort from oxygen therapy may be associated with dry mucus membranes or
increased work of breathing due to inadequate flow.

Oxygen toxicity is an inflammatory response of the lung tissue following exposure to 70100% oxygen for between 48 hours and 7 days. It impairs the action of the cilia,
macrophages and surfactant and the patient may experience substernal pain, cough,
dyspnoea, interstitial oedema, decreased lung compliance and possible pulmonary
fibrosis. (34)

Absorption atelectasis may occur if absorption of oxygen from alveoli exceeds
replenishment of alveolar gas, so that the alveoli are no longer held open by inert
nitrogen (nitrogen washout). This tends to occur most commonly in mechanically
ventilated patients receiving greater that 70% oxygen for more than 48 hours. (35)

A small proportion of patients with chronic Type II respiratory failure may develop
apnoea if their central hypoxic drive is removed by supplemental high dose oxygen
therapy. However, this is seldom (if ever) abrupt and a period of desaturation and
increasing drowsiness will alert staff before apnoea occurs. In these patients, initial
oxygen concentrations should be low (24-28%) and progressively increased on the basis
of repeated blood gas analysis. (19)

Psychological oxygen dependency.
27
Oxygen Delivery Systems
Oxygen delivery systems are conduits through with oxygen flows from the oxygen source to
the patient. They are classified into two major categories:

A fixed performance device which will deliver a known FiO2 by providing a sufficiently
high flow rate of premixed gas to exceed the patient's peak inspiratory flow rate. (36) For
example:
 spontaneously breathing tracheostomy patient with tracheostomy mask and venturi
valve. The venturi valve ensures that a proportion of room air is entrained through a
fixed-size port, so that specific oxygen concentrations can be delivered. The valves
are colour coded, according to the entrainment port size and the oxygen
concentration is pre-printed on the valve and ranges from 24-60%.
Figure 9:
Venturi Valve
 spontaneously breathing tracheostomy patient on a CPAP circuit or T-piece.
 mechanically ventilated tracheostomy patient.

A variable performance device which will deliver a variable FiO2 as the flow of oxygen is
less than the patient's peak inspiratory flow so that room air is entrained to dilute the
oxygen.(36) For example:
 spontaneously breathing tracheostomy patient on a tracheostomy mask with no
venturi valve.
Note: All oxygen dependent tracheostomy patients should receive humidified oxygen
therapy. The only exception to this is tracheostomy patients receiving oxygen
therapy via a venturi valve, where moisture condenses on reaching the valve which
affects the proportion of room air entrained through the fixed-size port. In this
circumstance, humidified oxygen therapy should be avoided but regular saline
nebulisation should be administered.
28
Prescription of Oxygen Therapy
Oxygen therapy should be prescribed.
The following information should be documented: (37) (38)

Flow rate

Concentration

Delivery device

Humidification

Duration

Method of monitoring
In the acute setting oxygen should be continuous and administered for the duration
prescribed. Intermittent oxygen prescription should only be considered if hypoxaemia occurs
during specific circumstances, for example during sleep or exercise.(33)
Monitoring Oxygen Therapy
Clinical assessment during oxygen administration should focus on the respiratory, cardiac
and neurological systems and should be performed on a regular basis throughout the day,
especially if any change in clinical condition or oxygen dosage has occurred.(33)
Adequacy and changes in arterial oxygenation should be monitored by pulse oximetry and/or
arterial blood gas analysis.(39)
Arterial blood gas analysis is considered the gold standard, however pulse oximetry is very
useful within the clinical setting as long as its limitations are recognised which include:(40)

inability to detect hypoventilation and a rising carbon dioxide level.

inaccurate reading associated with poor peripheral circulation, substance interference or
malpositioning.
(Note: Improper probe placement, or failure to monitor or change probe placement
may cause pressure injuries. As a result, the probe site should be changed
every 2-4 hours.) (12)
Discontinuation of Oxygen Therapy
In the post-operative patient oxygen therapy can be discontinued after the existing oxygen
prescription has elapsed if the patient is clinically stable and is maintaining a SpO2 above
94% at all times on room air.
In the critically ill patient, oxygen therapy can be discontinued when the patient has
recovered from critical illness and is clinically stable and maintaining a SpO 2 above 94% at
all times on air.
Oxygen therapy should always be restarted if clinically indicated.
29
STOMA CARE
Tracheostomy stoma care aims to keep the area clean and dry, reducing the risk of skin
irritation and infection. Secretions collected above the tracheostomy tube cuff may ooze out
of the surgical incision and stoma site. The resultant wetness can promote irritation of the
skin and can lead to skin maceration and excoriation. This increased moisture may act as a
medium for bacterial growth or prevent the stoma site from healing. (41)
Although the frequency of dressing changes will be indicated by the amount of secretion
oozing around the tracheostomy stoma and should be reviewed each shift, they should be
changed at least every 24 hours.
Assessment of the tracheostomy tube holder should be done every shift and changed at
least every 24 hours.
Requirements








Two practitioners
Sterile powder-free gloves
Dressing pack
Normal saline 0.9%
Pre-cut keyhole dressing
Tracheostomy tube holder
Orange clinical waste bag
Appropriate goggles and mask.
Emergency equipment and functional suction equipment should be readily available
at the bedside.
Prepare all equipment prior to the procedure.
Action
Rationale
Explain the procedure to the patient.
Gain consent (where appropriate) and
reduce anxiety.
Wash hands.
Wear goggles, mask, gloves and apron.
Reduces the risk of contamination.
If copious secretions are present, suction
prior to changing the tracheostomy tube
holder and dressing.
The patient is less likely to cough or
require suctioning during the procedure.
Position the patient with their neck slightly
extended.
The positioning of the patient allows easier
access to the stoma site.
30
Action
Rationale
Continue to administer oxygen throughout
the procedure if appropriate.
To reduce the risk of hypoxia.
One practitioner holds the tracheostomy
tube and the oxygen in place whilst the
second practitioner removes the tapes and
dressing.
To stabilise the tracheostomy tube and
reduce the risk of dislodgement of the
tracheostomy tube.
Discard these into the clinical waste
disposal bag immediately.
To reduce the risk of cross-infection.
If the tracheostomy tube has an inflated
cuff ensure the tube leading to the
external balloon is not damaged. If this
does occur the tracheostomy tube will
need to be replaced, therefore, inform
medical staff promptly.
This will deflate the cuff of the
tracheostomy tube and there will no longer
be a viable seal against the trachea
therefore the risk of aspiration is
increased.
Assess the tracheostomy stoma for signs
of trauma, infection or inflammation and
document in the Suction Chart.
Early detection and treatment reduces the
risk of deterioration of the stoma. (42)
Clean around the stoma with Normal
Saline 0.9%, if required, using a clean
technique. Dry thoroughly.
Other cleaning agents may cause irritation
to the tracheal mucosa and surrounding
skin.
Apply the keyhole dressing - starting from
below the tracheostomy tube.
A keyhole dressing is most appropriate as
bulky dressings raise the tracheostomy
tube and may cause discomfort to the
patient and can cause tube dislodgement.
Secure the tracheostomy tube in position
preferably with a tracheostomy tube
holder. The tube holder should be tight
enough to keep the tube securely in place
but loose enough to allow two fingers to fit
between the tube holder and the neck.
For patient comfort and to reduce trauma
from a migrating tracheostomy tube.
Dispose of used/soiled equipment in the
orange clinical waste bag and wash hands.
31
If the patient has a tracheostomy with an inner cannula then this should be removed at least
every 8 hours for assessment. The cannula should then be cleaned as required and/or
replaced and locked back in position.
Action
Rationale
To change the inner cannula firstly remove
the old one. With one hand hold the
tracheostomy in place.
To prevent the tube from dislodging when
the inner cannula is removed.
With the other hand twist the inner tube till
it unlocks and then remove in a downward
motion.
To ensure the tube slides out smoothly.
Insert the new tube and lock into place
If the tube is disposable then place in
orange clinical waste bag immediately.
To reduce the risk of cross-infection.
If the tube is non-disposable then it should
be cleaned with warm soapy water or
hydrogen peroxide 0.5%, rinsed and left to
dry.
The tube should never be left to soak due
to the increased risk of bacterial
contamination.
Do not clean inner tube with a brush.
Brushes can scratch the inside of the tube
causing an area for bacteria to grow.
32
ORAL HYGIENE
Patients with tracheostomies require regular oral care due to the reduced evaporation of oral
secretions, which accumulate in the mouth. This is due to the disruption of normal airflow
during inhalation and exhalation.
Aspirated infective saliva contributes to respiratory problems.
If the patient presents with a dry mouth then consider artificial saliva.
Important Points





Hardened plaque causes tartar.
Tartar tends to form faster in NG/PEG tube fed patients - plaque removal is a priority.
Regular oral hygiene - minimum x 2 per day but preferably every 2-4 hours.
Patient’s teeth should be brushed with toothbrush and toothpaste at least twice a day.
(Remember the patient may be self-caring.)
There is no reason why patients with tracheostomies can’t wear their dentures.
PERSONAL HYGIENE
Showering is permitted if the patient will tolerate oxygen being off for the duration of the
shower and the tracheostomy is covered with a Heat Moisture Exchange Device
(HME)/Thermovent/Swedish Nose. Ensure the patient is angled away from shower spray. It
is easier if the shower is angled from behind.
33
HUMIDIFICATION
INDICATION
It is mandatory that a method of artificial humidification is utilised when a
tracheostomy tube is in situ.(43) The type of humidification will be dictated by the
needs of the patient. Advice may be sought from the physiotherapist.
Rationale
In normal breathing, inspired air is warmed, filtered and moistened by ciliated epithelial cells
in the nose and upper airways. However, these humidifying functions are impaired by:(4)
a) a tracheostomy tube, which bypasses natural mechanisms for warming/moistening
inspired air.
b) administration of cold, dry inspired gases (eg oxygen therapy).
Inadequate humidification can result in a number of physiological changes including:(44)
a) Retention of viscous, tenacious secretions
b) Impaired mucociliary transport
c) Inflammatory changes and necrosis of epithelium
d) Impaired ciliary activity
e) Destruction of cellular surface of airway
(eg
inflammation/ulceration)
f)
(eg
atelectasis/pneumonia)
Reduction in lung function
g) Increased risk of bacterial infiltration.
As a result, humidification must be artificially supplemented to assist normal function and
facilitate secretion removal.
Failure to adequately humidify could result in tube occlusion because secretions
become dry and viscous, forming a crust around the tracheostomy. (17)

Indications for Use

Tracheostomy patients who are mechanically ventilated/receiving oxygen therapy/or selfventilating on air.
Relevant Information

Procedure involves administration of 5 mls 0.9% sterile normal saline into the nebuliser
unit 2-4 hourly or as required.

Nebulisers must be connected to a gas source with a flow rate of 6-8 litres/minute (or
follow manufacturer's guidelines).

Lung deposition is enhanced by slow deep breathing and the side lying or upright sitting
position.

Hypertonic saline increases sputum clearance by increasing production, so is only used
to induce sputum for diagnostic purposes.(51)

Ensure nebulisation is given via the tracheostomy (not the face mask!). A nebuliser can
be attached to tracheostomy mask or T-piece circuit.

Limitations of Procedure/Device

Only small percentage of output deposits in the airway (<10%).(52)

Efficiency of device is
(i)
technique dependent
eg
co-ordination
breathing pattern
inspiration hold
(ii)
design dependent
eg
output
particle size
(iii)
patient dependent
eg
compliance
Hazards/Complications

Bronchospasm(50)



Supplemental oxygen therapy may be added.
40
Hazards/Complications
HME devices should be avoided in patients with:


thick, copious secretions(56)
body temperature <32°C(43)
Hazards associated with the use of HME devices include:



Possible hypoventilation due to increased dead space
Possible increased resistive work of breathing which would be exacerbated by
mucus plugging in the airways.
HME devices should be checked every 4 hours and replaced if soiled, as secretions can
block the filter and increase work of breathing.(4)

CHANGING OF TRACHEOSTOMY TUBES
Changing of the tracheostomy tube should be a multidisciplinary decision. The first change
should always be performed or supervised by a suitably trained member of the medical staff.
This is because the stoma and tract to the skin from the patient's trachea may not be well
formed. Thereafter changing the tube can be performed by a competent and suitably trained
person but medical assistance should be readily available at all times.
Indications for Tube Change

Every 28-30 days or as clinical need dictates.(57)

Evidence of tracheostomy tube obstruction that may lead to a rapid deterioration in the
patient's respiratory status.

Infection around stoma site.

Part of weaning process.
Equipment Required
1. Two tracheostomy tubes of appropriate make.
 1 same size
 1 size smaller.
2. Tracheostomy tube tape
3. Tracheostomy tube holder
4. Dressing Pack
5. Normal saline (0.9%) to clean
6. 10 ml syringe
7. Sterile gloves and protective eye wear
8. Water soluble lubricating gel
9. Tracheal dilators
10. Forceps and scissors
11. Pen torch
12. Suction and suction catheters
13. An exchange device/Bougie
14. Precut keyhole tracheostomy dressing – uncut gauze swabs are not recommended.
15. Cuff manometer.
Action
Rationale

Explain procedure to the patient and the
rationale for why the tracheostomy tube
needs changed.

The patient should give verbal consent
where possible unless the tracheostomy
tube is changed as an emergency.

Stop enteral tube feeding or ensure nil by
mouth 1 hour prior to tracheostomy tube
change.

Removal of tracheostomy tube means
the airway is unprotected. It is therefore
important to reduce the risk of aspiration
during tube change.(9)
43
Action
Rationale

Position patient on bed in upright sitting
position with neck extended.

The patient should be comfortable during
the procedure. Extending the neck will
make the removal and insertion of the
tracheostomy tube easier.

Wash hands and put on disposable
plastic apron, gloves and goggles.

Reduces risk of cross infection(11)

Hyperoxygenate patient with 100%
oxygen if they are oxygen dependent
(>40% oxygen) and monitor their oxygen
saturation levels.

During tracheostomy tube change the
patient will not receive oxygen and may
be at risk of hypoxia.
Medical staff should be present if the
patient is oxygen dependent.

COPD patients may have an altered
carbon dioxide response mechanism and
therefore should not routinely be given
100% oxygen.(19)

Two skilled practitioners should perform
the procedure.

One person to deflate the cuff prior to
tube removal and the other to perform
suctioning while reassuring the patient.

Open the new tracheostomy tube on to
an opened dressing pack. Put on sterile
gloves.

To reduce the risk of cross infection.

If new tracheostomy tube is cuffed, check
the cuff by inflating it, removing the
syringe and observing that it does not
deflate spontaneously, then deflate with
a 10 ml syringe before insertion.

To check for air leaks within the cuff.

Check that the exchange device can be
removed.

To become familiar with removing the
exchange device prior to insertion.

Lubricate
the
tracheostomy
sparingly with water soluble gel.

To facilitate insertion.

tube
Do not use the tube if
spontaneously deflates.
the cuff
Too much gel may irritate the trachea.
Remove the old dressing and clean
around stoma site.
44

To clean skin of debris and superficial
organisms.
Action
Rationale

Use a pen torch to ensure tissue is
healthy.

Prior to deflating the cuff, suction briefly
with a suction catheter in the oropharynx.

Secretions may pool at the top of the cuff
and when it is deflated may enter the
lungs.

Perform
synchronised
suction/cuff
deflation technique as follows:

Saliva and bile may collect above the
cuff, which on deflation will enter the
bronchus if the patient has an inadequate
cough.
Simultaneous suction should
enable secretions to be caught and
removed as they pass the gradually
deflating cuff.(12)
 Pass a sterile suction catheter into
the tracheostomy tube approximately
0.5 cm longer than the tracheostomy
tube tip.

Minimise risk of cross infection and
trauma.
 Simultaneously
the
second
practitioner should remove air in 0.5
ml increments from the tracheostomy
cuff until fully deflated using a 10 ml
syringe. Encourage the patient to
cough.

The cuff needs to be fully deflated to
reduce the risk of trauma from removing
the tracheostomy tube. Gradual deflation
of the cuff allows the patient to adapt to
the feeling of being able to breathe
through their nose and mouth again.

Coughing reduces the risk of aspiration.

Release tracheostomy ties and remove
the old tracheostomy tube in a firm
outward and downward motion.

The tube may be slightly resistant and
firm pressure may be required.

Ensure the stoma does not occlude due
to a large double chin.

This will ensure that the patient can
breathe whilst the tube is out.

Successful Tube Insertion
Action

Rationale
Secure the tracheostomy tube with a
tube holder or tapes. Clean around
stoma site again if necessary. Renew
tracheostomy dressing.

Inflate the cuff using a 10 ml syringe
inserting air gradually in 0.5 ml
increments until the balloon is inflated.

Assess cuff pressure using a manometer
(cuff inflation should not exceed 30
cmH2O) and adjust as required using the
syringe.

Ensure the patient is breathing
comfortably.
Return oxygen to preprocedure setting and observe saturation
levels.

Record the tube change in the medical
and nursing notes. Document time, date,
size, type of tube and any complications
experienced during the procedure.

There may be a small amount of
bleeding following a tracheostomy tube
change. If there is excessive bleeding,
ensure the cuff is inflated and seek
medical assistance.
47

To reduce the risk of dislodgment,
maintain patient comfort and reduce the
risk of infection.

Ensure tapes are not secured too tightly.

Pressure exerted on the tracheal wall
greater than 30 cmH2O may result in
capillary occlusion, tissue necrosis and
tracheal stenosis.(8)

An inflated cuff reduces the risk of
aspiration.

Trauma can occur to stoma site and the
patient's trachea when changing the
tube. An inflated cuff will protect the
patient's airway.
Unsuccessful Tube Insertion
Action
Rationale

If the tube insertion fails or the patient
appears distressed and cyanosed call an
anaesthetist.

Insert the sterile tracheal dilators and
attempt to re-insert firstly the same tube
and then move to a smaller tracheostomy
tube.

If this fails follow the EMERGENCY
ALGORITHM see Appendix III.
48

The tract may not have formed or the
tracheostomy tube may have become
inadvertently blocked during insertion
causing failure to re-intubate the patient.

GUIDELINES FOR WEANING FROM A CUFFED TRACHEOSTOMY AND
REMOVAL OF A TRACHEOSTOMY TUBE
Weaning can be commenced once the following have been ensured/initiated:




the primary cause for the tracheostomy has been resolved
there is stable lung status (with oxygen therapy less than 40%)(58)
effective swallow and cough reflex are present (where possible)
safe oral feeding and/or artificial nutrition has been established.
Action
Rationale

Full explanation of procedure must be
given to the patient and carers.

Alleviates any anxiety.

The weaning programme must be
planned, clearly documented and
regularly evaluated by the members of
the multi-disciplinary team.

Ensures continuity and individualised care.

The patient should be placed in
maximum view of nursing staff with a call
bell within easy reach, if appropriate.

Ensures maximum observation of the
patient and allows the patient to summon
urgent assistance if necessary.


50
Action
Rationale
 Perform synchronised suction/cuff
deflation technique as follows:


Simultaneous suction should enable
secretions to be caught and removed as
they pass the gradually deflating cuff.

Pass the sterile suction catheter
into the tracheostomy tube
approximately 0.5 cm longer than
the tracheostomy tube tip.

To minimise the risk of cross infection and
trauma.

Simultaneously
the
second
practitioner should remove air in
0.5 ml increments from the
tracheostomy cuff until fully
deflated using a 10 ml syringe.
Encourage the patient to cough.

Gradual deflation assists the patient to
adjust to changes in airflow(12) and allows
the patient to adapt to the feeling of being
able to breathe through their nose and
mouth again.

Coughing reduces the risk of aspiration.

The patient is at risk of aspiration. These
signs will provide early indication that the
patient is unable to maintain their own
airway.

No Respiratory Distress
Action

Rationale
If no signs of respiratory distress are
noted, leave the cuff deflated.

Builds patient's confidence and ensures
patient has coped well with cuff deflation.
Observe the patient for 24 hours ensuring
they have a call bell within easy reach if
appropriate.

52
To ensure adequate availability of medical,
nursing and physiotherapy staff if the patient
experiences difficulties post tracheostomy
removal.
Action

Rationale
Indications for tracheostomy removal
include:
 maintaining own airway
 tolerates full cuff deflation for more
than 24 hours
 adequate cough
 oxygen weaned to 40% or less(58)
 CV stable
 SpO2 stable
 minimal secretion production.

A mini tracheostomy should be
considered by the multidisciplinary team
if:
 reduced ability to clear secretions
 all other observations stable

The patient is fully informed about the
procedure.

Ensure that the essential equipment is at
the bedside:

A mini tracheostomy should only be
considered if the patient is able to maintain
their own airway and is not at risk of
aspiration.

This will allow nursing staff and
physiotherapists to aid clearance of
patient's secretions.

Oxygen therapy must be administered via
a face mask.

Alleviates unnecessary anxiety.
 Refer to page 43.

Ensure the patient is sitting in an upright
position.

To optimise lung expansion and facilitate
swallowing. (10)

Wash hands and put on a disposable
plastic apron, gloves and goggles.

Minimise cross infection.(11)

Release tracheostomy ties.
53
Action


Rationale
With a sterile gloved hand, pass a
connected suction catheter in to the
tracheostomy tube 0.5 beyond the tip.
The second person should then gently
but firmly withdraw the tube in an
outward and downward movement.
Suction should be applied while the tube
is removed.

The tracheostomy tube has to follow the
anatomical formation of the track. Rapid
jerking or pulling the tube upwards will
cause trauma to the trachea and acute
discomfort for the patient.
Suction is
applied to clear secretions and mucus as
tube is withdrawn.

The tube may be slightly resistant and firm
pressure may be required.

Sleek is no longer advocated as it is
difficult to
(a) ensure an effective seal
(b) remove – causing blisters etc.
(c) observe when there is soakage.

BEDSIDE EVALUATION OF SWALLOWING, EATING AND DRINKING
Not all patients with a tracheostomy will have a swallowing problem.(60)
The "gold standard" is feeding the patient with a deflated tracheostomy cuff. Feeding a
patient with an inflated cuff is not recommended, however under special circumstances it is
recognised that this may be necessary. The decision to feed the patient with an inflated cuff
should be a multidisciplinary team decision.
Speech and language therapists are only involved in the assessment and management of
tracheostomised patients who present with swallowing difficulties.
1. Screening Procedure for Swallowing Difficulties in Tracheostomised Patients(61)
Action
Rationale
1. A senior nurse, who is trained in the Blue
Dye Test procedure, will screen patient's
swallowing ability where appropriate.
To ensure correct administration and
interpretation of the Blue Dye Test.(61)
A Blue Dye Test should be carried out to help
determine gross airway competence.
2. It is not usually recommended that patients
eat with a fully inflated cuff and it is
advisable that the tracheostomy cuff be
deflated for all oral intake.(62)
The purpose of the tracheostomy cuff is to
promote respiration not to stop aspiration.(12)
Laryngeal elevation is reduced by the
anchoring effect of an inflated cuff. Normal
clearing of the larynx by pulmonary air during
swallowing is prevented by an inflated cuff.(12)
3. Before the cuff is deflated, senior medical
staff agreement is necessary. This must
be documented in the medical notes.
Aspiration
risk
should
be
avoided.
Respiratory support processes will be affected
by ventilated cuff deflation.
4. It is recommended that nasogastric/
gastrostomy feeding be turned off one hour
prior to cuff deflation and the swallow
assessment.
This is to reduce the risk of vomiting and
regurgitation and subsequent aspiration.
5. The patient should be sitting in an upright
position either in bed or in a chair, the head
flexed slightly towards the chest.
The patient is at increased risk of aspiration if
in a semi-upright position with the neck
extended.(63)
6. If not already in situ, attach Pulse Oximeter
to monitor oxygen saturations.
A decrease in oxygen saturations may
indicate aspiration.(64) (65)
7. Deflate cuff following "Deflating /Inflating a
Cuff" Guidelines (page 16).
57
Action
Rationale
8. Follow the "The Blue Dye Test for
Tracheostomised Patients" Appendix IV. If
the test is positive, refer to the speech and
language therapist.
If negative, follow
"Introduction
of
oral
intake
with
Tracheostomised Patients who do not
Present with Dysphagia" see below.
It is essential that the Blue Dye Test(66) (67)
results are taken along with other clinical
indicators to ensure reliability.
2. Introduction of Oral Intake with Tracheostomised Patients who do not Present with
Dysphagia
Action
Rationale
Turn off nasogastric/gastrostomy feed one
hour prior to feeding.
This is to reduce the risk of vomiting and
regurgitation and subsequent aspiration.
The patient should be sitting in an upright
position either in bed or on a chair, the head
flexed slightly towards the chest.
The patient is at increased risk of aspiration if
in a semi-upright position and the neck
extended.(63)
Before cuff deflation, suction the oropharynx
and through the tracheostomy tube.
Pooling of secretions may occur above an
inflated cuff and these may enter the lungs
following cuff deflation.
The cuff should be fully deflated for all oral
intake, providing the patient's toleration of this
has been agreed.
Pressure on the oesophagus can be a result
of a fully inflated cuff. Refer to rationale for
cuff deflation in "Screening Procedure" (part 1
above).(68)
The cuff MUST BE DEFLATED BEFORE a
speaking valve is applied (refer to page 61,
point 9).
Where a speaking valve is used, attach it to
the tracheostomy tube. Refer to each patient's
weaning plan to check toleration times for the
speaking valve.
This will
airflow.(69)
create
optimum
supraglottic
Where the tracheostomy tube is fenestrated,
ensure the inner cannula is also fenestrated if
possible. If not, the inner cannula should be
removed prior to attachment of the speaking
valve.
The patient should be fed by a nurse.
The nurse will be able to control bolus size
and observe for signs of aspiration.
Cautiously introduce Stage 2 (puréed) diet
(see Appendix VI) and thin fluids. Use a
teaspoon for both consistencies.
Stage 2 (puréed) diet is considered the most
manageable consistency for initial swallow
trials.
58
Action
Rationale
Patient's voice quality and cough should be
regularly
checked
by
occluding
the
tracheostomy tube with a gloved finger and
asking the patient to say "ah". If a speaking
valve is in situ, similarly ask the patient to say
"ah" or count to 5. If the voice quality is "wet"
or "gurgly" then ask the patient to cough and to
swallow again. Oral intake must then be
discontinued and referral made to the speech
and language therapist.
If voice quality is "wet" or "gurgly" then this
may be indicative of aspiration.
If voice quality is clear then continue with
swallow trial process.
Observe for the following signs during oral feeding trials:






the patient’s condition deteriorates
the patient fatigues
if indicated by the patient’s respiratory status (eg signs of distress, increased respiratory
rate, decreased oxygen saturations)
voice is consistently sounding wet
persistent coughing is evident (in association with eating and drinking)
there are signs of aspiration on tracheal suctioning.
Consider referral to the Speech and Language Therapy Department if these symptoms
occur in relation to oral intake
3. When to Consider a Referral to the Speech and Language Therapy Department for
a Swallowing Assessment
Referral would be appropriate for tracheostomised patients with:
(i)
Neurological involvement eg bulbar involvement.
(ii)
Head and neck surgery.
(iii)
Evidence of aspiration of food/fluid/oral secretions on tracheal suctioning.
(iv)
Persistent wet or weak voice when cuff is deflated and speaking valve or decannulation
cap is in place.
(v)
Evidence of blue dye on suctioning following a Blue Dye Test.
4. Nursing Management
Action
Rationale
Follow the recommendations of the speech
and language therapist regarding swallow
safety guidelines, such as patient positioning,
swallow manœuvres and modified textures
(Stage Diet). This must be recorded in the
nursing kardex and medical records.
The patient may be at risk of aspiration of
one or more consistencies.
59
FEEDING
Most patients will initially be fed via a nasogastric tube. All patients must be referred to a
dietitian for assessment and prescription of appropriate feed. Please refer to ward protocols
for care of nasogastric feeds.
When patients are to progress to oral diet for the first time a blue dye screening assessment
should be performed by nursing staff (see Bedside Evaluation of Swallowing, Eating and
Drinking page 56). If the patient shows any signs of difficulty or if there are any concerns for
the safety of the patient's swallow, then the patient should be referred to the speech and
language therapist. Individual care plans will then be drawn up and documented in the
nursing kardex.
The dietitian should be informed of patient's progress from tube feeding to oral diet so that
advice on transitional feeding may be given. Patients following Stage 2 and Stage 3 diets
are unlikely to meet their nutritional requirements without the intervention of a dietitian.
The following terminology was agreed by the Grampian Dysphagia Management Group
(Appendix VI).
STAGING OF DIET
Stage1:
(nil orally)



Nothing to eat or drink.
Administration of medications should be through an NG tube.
Swallow assessments should be ongoing.
Stage 2:
(puréed diet)






Thick smooth consistencies only.
If not managing normal fluids then they can be thickened.
Order thick and creamy yoghurts, weetabix, etc from the menu card.
Document Stage 2 on the menu card for lunch and supper.
The patient should be sitting upright and be fed by the nurse.
Medication should still be given via the NG tube yet can be crushed
and given in food also.
Stage 3:
(soft diet)





Soft food only.
Order the soft option from the normal menu.
Order thick and creamy yoghurts for dessert with each meal.
Again fluids may need to be thickened.
Patients can this time feed themselves if able but should still have
close nursing supervision.
Patients will probably be able to manage medication orally yet it may
still have to be crushed or syrup used.

Stage 4:
(normal diet)



Normal diet.
Normal fluids.
Patient may still require supervision.
60
COMMUNICATION
Points to consider:
1. Where appropriate before the tracheostomy procedure, the patient and relatives should
be informed, that the patient may be unable to create a voice while the tracheostomy
tube is in place. This is because as air is no longer passing through the vocal cords.
They should be reassured that it is expected that the patient's voice will return once the
tube is removed or manipulated (except when a laryngectomy has been performed).
Alternative means of communication can be provided by the multidisciplinary team and
an information sheet is available (see Appendix V).
2. For tracheostomised patients, the initial assessment should include a focus on the
patient’s ability to see, hear, touch, write, understand or use facial expressions such as
smiling and blinking.(70)
3. Some tracheostomy patients may only be able to communicate by mouthing words or by
use of a predetermined coded blink.
4. If lip-reading is used, ask the patient to exaggerate their lip movements and to speak in
short but complete sentences in order to make the message clearer.
5. Watch the patient’s facial expressions and gestures for clues and listen for key words,
which may indicate what the patient is saying.
6. If a coded eye-blink is the only means of communication available, instruct the patient to
blink once for "YES" and twice for "NO" in response to your questions.
7. Consider referral to the Speech and Language Therapy Department if individualised
boards or communication aids are felt to be appropriate to meet the patient’s needs.
8. Electronic larynx and electronic communication aids may be appropriate. The speech
and language therapist will assess the patient for the appropriate equipment and advise
the patient and their carers on how to use them.
9. Where the patient can tolerate cuff deflation it may be appropriate, in consultation with
the Multidisciplinary Team, to consider a one-way speaking valve. This is attached to
the hub of the tracheostomy tube redirecting expired air through the larynx providing the
potential to produce speech. Referrals to the Speech and Language Therapy
Department for assessment of patient's suitability for a speaking valve should be
considered. A speaking valve may have additional benefits in improving the patient's
swallowing ability or in facilitating the weaning process.

Appendix V
COMMUNICATING WITH A PATIENT WITH A TRACHEOSTOMY
Communication serves to meet many patient needs including “social interaction, information
giving, reassurance, discussion of feelings, advice and counselling”.(71)
“The purpose of communication for critically ill patients is to help them maintain their identity
as well as psychological, structural, personal and social integrity.”(71)
The psychological status of the patient must be considered as they may be unable to speak
and will often be anxious in the hospital environment.
These points are intended for those patients who are unable to talk.
The patient has most of their day to day needs met however they may have questions or
concerns.
Following some of these ideas may help to structure communication
opportunities.

Keep conversations short.

Share interesting information about family and friends.

While in the patient's presence, talk to the person – not about the person.

When talking pause frequently to give the person time to try to respond, this may be
limited to eye movement or facial expression.

Can the patient indicate "yes" and "no" (for example, nodding and shaking head; one
blink for "yes" and two for "no"; thumbs up/down)? Can they use a pen and paper?
If "yes" and "no" is established, please structure your questions to allow the patient to
respond.

If using a communication aid eg alphabet board/picture board/lightwriter, you need to
know the following:

Does the patient know how to use it?

Does the patient want to complete words/sentences or are they happy for you to
predict what they say?

Are they using it appropriately?
