11.7 NCPAP / DUOPAP
In nCPAP / DUOPAP mode the patient breathes spontaneously from a mask or nasal prongs.
A NIV Trigger option can be enabled to provide these modes with Breath detection (Apnea
monitoring with Alarms) and triggered supported breaths (or Synchronized Transition from low
to high CPAP levels) in DUOPAP.
Depending on the nasal generator being used, fabian will automatically select the proper NIV
Trigger Sensor:
• Flow Sensor (Neonatal) with Infant Flow (Infant Flow or Inspire) and Infant Flow LP
generators
• Pressure Sensor with Medijet (by Medin) generator
Additionally, monitoring SpO
2
and PtCO
2
is always recommended.
nCPAP: Supplies a positive Airway Pressure with automatic Leak Compensation.
The maximum flow compensation is selectable by menu.
DUOPAP: Same as nCPAP but with the option of Positive Pressure Ventilation with
adjustable frequency and Inspiratory Period.
This mode requires a special nCPAP Patient Set with nCPAP generator.
Before using the nCPAP / DUOPAP mode the correct system must be specified
in the specifications menu.
The following systems currently can be used:
• Infant Flow (Infant Flow or Inspire)
• Infant Flow LP
• MediJet
When ventilating a patient using a nasal interface in nCPAP or DUOPAP modes,
the clinician must make a compromise between providing additional flow to
compensate for a leak at the nose, or providing an alarm to warn of a leak,
particularly when the appropriate size prongs are small. For a patient who is
capable of spontaneous breathing without support, leak compensation may
be set to a high setting, in order to provide additional flow to compensate for a
leak at the interface between the prongs and the nose. This will provide a
more stable pressure support in the presence of variable leak (for example,
with patient movement). However in this scenario, the ventilator may fail to
provide an alarm in the event of decannulation.
For a patient who requires an alarm in the event of decannulation, leak
compensation should be set to a low setting. This will provide less stable
pressure support in the presence of variable leak at the nose, but a reliable
alarm for decannulation.

If Inspiratory Time is set lower than 1 second; the maximum Pressure may NOT
be reached.
