Patient Circuit
Patient circuit is a disposable, dual limb system
 All hoses attach to the side of the ventilator
 Patient end connects for clinical intervention
 Directly to an endotracheal tube
 Use NIV kit to provide nasal prong or nasal mask
application in neonates and infants
 Use full face CPAP mask (non-vented)
Patient Circuit
Which size circuit - Neonatal or Pediatric?
 The neonatal circuit uses 10 mm hoses and is designed for
patients up to 3 kg
 The pediatric circuit uses 15 mm hoses and is designed for
patients above 3 kg
 If your patient needs 10 L/min or more continuous flow to
meet spontaneous flow demand, you should use the pediatric
circuit to minimize expiratory flow resistance
Patient Circuit
Use only Airon Corporation patient circuits
 Calibration of the PEEP / CPAP and Peak Pressure controls is
based on the Airon circuit and exhalation valve
 Using other manufacturers circuits / exhalation valve may
cause:
 errors in pressure delivery
 high expiratory flow resistance
 interference with CPAP setting
Program Objectives
pNeuton mini Ventilator self guided tour,
objectives completed so far
 Describe the main operating features of the
ventilator
 Identify the controls and connections
 Describe the patient circuit
With an understanding of pNeuton’s capabilities,
let’s look at patient application.
Patient Application
Set Main Controls
 PEEP / CPAP can be set
to minimum
 Determine peak
ventilating pressure
 Set desired continuous
flow to meet patient needs
 Set Inspiratory Time
 Set Expiratory Time
 Choose % Oxygen
 Adjust High Pressure
Alarm for safety
Patient Application
Initial Set-up
 Attach Airon patient circuit
to ventilator
 Attach a test lung to the
patient connection on the
circuit
 Attach high pressure
oxygen and air hoses to the
side of the ventilator
 Attach these hoses to the
gas supplies
Patient Application
Begin Ventilation
 Turn ON gas supplies
 Alarm system will
immediately activate
 Press Alarm Silence button if
desired
 For IMV or CMV, set Mode
control to IMV+CPAP
 Ventilator will start to provide
breaths at the settings on the
controls
Patient Application
Set PEEP / CPAP
 Adjust the PEEP / CPAP
control to the level desired
 Adjust continuous flow to
meet patient demand – not
too high to create expiratory
flow resistance – not to low
to cause pressure swings
and high patient effort
 Use 6 – 8 for neonates
 Use 8 - 10 for infants
 Use 10 – 20 for children
Ventilator Operation
Alarm System Functionality
 Alarm preset to activate within 10 seconds
 Pressing the Alarm Silence button equals 25 second
delay
 Disconnect Alarm is looking for a specific
minimum pressure of at least 3 cm H2O at all times
 If there is not at least 3 cm H2O CPAP or mandatory
breaths pressure of 3 cm H2O, the alarm will sound
 High pressure alarm activates whenever the
pressure in the circuit exceeds the alarm control
setting.
 Input Gas Pressure below 40 psi (2.8 bar) will
activate the alarm
Ventilator Operation
Peak Pressure Limit
 Operates to limit the peak airway
pressure during mandatory
breaths
 For volume ventilation, set the
Peak Pressure 10 cm H2O above
the pressure needed to deliver the
set Tidal Volume
 Peak Pressure control is not an
alarm. Use the High Pressure
Alarm control for this function
Ventilator Operation
% Oxygen Control
 Set % Oxygen control to the
desired oxygen level
 Accuracy is plus / minus 3%
 The ventilator uses the oxygen
gas supply for internal operation
so high oxygen concentrations
may deplete tanks quicker
Clinical Issues
Neonatal Ventilation
 Inspiratory time setting 0.25 to 2.0 sec
 Use low continuous flow for proper
breath delivery and minimize expiratory
flow resistance
 Inspiratory time, flow and pressure (along
with lung compliance / resistance and
ET-Tube leak) will determine tidal volume
to the patient
 Use the respiratory rate chart on top of
the ventilator to estimate ventilator rate
 Use NIV kit for nCPAP
 Monitor closely for patient synchrony
Clinical Issues
Non-invasive Ventilation (NIV)
 Use Airon NIV kit with nasal prongs or
masks
 Proximal pressure measured will
display on pressure gauge and be
used by alarm system
 Effective patient interface seal will
insure proper alarms
 Rotate from nasal masks to prongs
every few hours for patient comfort and
proper skin care
Clinical Issues
Pediatric Volume Ventilation
 Set the Peak Pressure to a safe
pressure level
 Refer to the Tidal volume chart on
the top of the ventilator for I-Time /
Flow combinations to determine the
proper settings for the tidal volume
desired
 Adjust Inspiratory Time control / flow
to increase or decrease tidal volume
- more flow or time equals larger tidal
volume
 Adjust PEEP / CPAP to established
baseline pressure
Clinical Issues
MRI Operation
 pNeuton mini is compatible with MRI
scanners up to 3 Tesla in strength
 While tests show that pNeuton functions at
the bore of the MRI unit, a minimum
proximity of 12 inches (0.3 meter) from the
bore is recommended
 Safe MRI practice calls for all devices used
in the proximity of a MRI scanner, including
pNeuton mini, be anchored to prevent
inadvertent movement
Clinical Issues
Altitude Operation
 The pNeuton mini may be used for air
transports in unpressurized cabins up to
15,000 feet
 Inspiratory time will increase and expiratory
time will decrease as altitude increases
 Pressure settings will not change as altitude
changes
 Always use external monitors and pulse
oximeters to monitor your patient
Patient Safety
pNeuton - Patient Safety Features
 Audible and Visual Alarms for patient
disconnect, high pressure and low supply
gas pressure
 High Pressure Release – pressure is
relieved at the Peak Pressure control
setting
 Internal Safety Pressure Release – limits
circuit pressure to 70 cm H2O, regardless
of the setting of the Peak Pressure control
 Anti-Suffocation System – in the event of
ventilator malfunction an internal valve will
allow ambient air to enter the patient circuit
Cleaning and Maintenance
 Clean ventilator between patient use
applications using a soft cloth and a mild
detergent / disinfectant
 Do not immerse the ventilator in water
 Patient circuit is disposable, single use
application and should not be cleaned,
disinfected or reused
 Ventilator should receive preventative
maintenance every 2 years
