Respiratory anatomy
Alveoli at the terminal end of the lower airway
Clinical Manifestations
1. Local Manifestations





Cough
 chronic, paroxysmal, dry , productive
Excessive Nasal Secretion
Expectoration of Sputum
 mucoid, purulent, mucopurulent, rusty,
hemoptysis
Pain
 pleuritic, intercostal, generalized chest
pain
Dyspnea- shortness of breath
Function
Gases are moved in and out of the lung
through pressure changes.
Intrapleural pressure is negative (less
than atmospheric pressure –
760mmHg)
Please refer to suggested reading notes
Clinical Manifestations
2. Systemic Manifestations
 Hypoxemia
 insufficient oxygenation of the blood
 cyanosis- bluish, grayish discoloration of skin &
mucous membranes
 Hypoxia
 inadequate tissue oxygenation
 Hypercapnia
 CO2 in arterial blood above normal limits
 Hypocapnia
 CO2 in arterial blood below normal limits
 Respiratory Failure
Medical Terminology
(Respiratory conditions)
Respiratory Failure: The inability of 
the cardovascular and pulmonary
systems to maintain an adequate
exchange of oxygen and carbondioxide
in the lungs.
Maybe caused by a failure in oxygen or 
in ventilation.
Can be hypoxemic or hypercapneic. 
Medical terminology cont.
Ventilation: the process of moving 
gases into and out of the lungs
Work of Breathing: The effort required
for expanding and contracting of the
lungs. The influencing factors: the rate
and depth of breathing, the ease in
which the lungs can be expanded and
airway resistance

pattern, maintain normal ABGs, increase
activity with decrease SOB or fatigue,
maintain weight, and less anxious with
episodes of SOB
Bronchitis






Inflammation of the bronchi caused by irritants
or infection
hypertrophy & hypersecretion of mucous- cause
increase in sputum production
increase mucous- decrease airway lumen sizelumen becomes colonized with bacteria.
Bronchial wall becomes scarred - leads to
stenosis & airway obstruction
Defined as a productive cough that lasts 3
months a year for 2 consecutive years with other
causes excluded.
Cough in the morning with sputum production is
indicative of Chronic Bronchitis
Bronchitis
Risk Factors: cigarette smoking, exposure to
pollution, hazardous airborne substances
Clinical Manifestations: productive cough,
dyspnea esp. on exertion, wheezing, use of
accessory muscles to breathe, cyanosis- “blue
bloater”, clubbed fingers
Interventions:
 Assess patency of airway- suction if cough
ineffective, RR, accessory muscle use, lung
sounds, skin color changes, ABGs
 Encourage high fluid intake & instruct in effective
breathing & coughing
 Monitor oxygen administration & aerosol therapy
Chronic Bronchitis
Encourage to report sputum changes or
worsening of symptoms
 Encourage exercise to improve resp. fitness
 Counsel to avoid respiratory irritants and stop
smoking
 Immunize against common flu and pneumonia
Pharmacology:
 Antibiotic therapy- Tequin, Levaquin
 Bronchodilators- Albuterol, Combivent,
Theophylline
 Corticosteroids- Prednisone, Solumedrol

Bronchiolitis:Bronchiolitis is a common illness
of the respiratory tract

usually caused by viral infection. It affects the
tiny airways, called the bronchioles, that lead to
the lungs. As these airways become inflamed,
they swell and fill with mucus, making
breathing difficult.
The variable degrees of obstruction produced in
air passage by these changes lead to
hyperpnoea & progressive emphysema.
Bronchiolitis:
Nursing Assessment
Sometimes more severe respiratory
difficulties gradually develop:
Rapid, shallow breathing.
Drawing in of the neck and chest with
each breath, known as retractions.
Flaring of the nostrils.
Irritability, with difficulty sleeping and
signs of fatigue or lethargy.
Bronchiolitis
Nursing care:
Follow strict precautions to prevent spread
of infection.
Administer high humidified oxygen.
Clear nasal congestion, try a bulb syringe
and saline (saltwater) nose drops.
Provide adequate Ng. Care for vomiting,
fever, & diarrhea.
Small frequent diet, & increase fluid intake.


A lung abscess is a localized area of lung
destruction
liquefaction necrosis usually related to pyogenic
bacteria
Cavity formation
