Independent audible and visual alarm from the Peak Pressure Control

20. 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)

21. 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

22. 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

23. 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.

24. 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

25. 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

26. 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

27. 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 for infants
Use 10 – 20 for children

28. 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

29. 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

30. 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

31. 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

32. 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

33. 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

34. 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

35. 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

36. 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

37. 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

38. Program Objectives pNeuton mini Ventilator self guided tour
