In PC-Dual PAP mode, you can set the following apnea vent function parameters as required:
1. [Apnea Vent]: Switch for turning on apnea vent function
2. [Apnea Vt]: Tidal volume in apnea ventilation
3. [Apnea Rate]: Frequency of apnea ventilation
4. [Apnea Tinsp]: Inspiration time of apnea ventilation
In PPC-Dual PAP mode, you can set the following sigh function parameters as required:
1. [ Sigh ]: Switch for turning on sigh function
2. [ Interval ]: Number of sigh cycles
3. [ Delta Pinsp ]: Inspiration pressure of sigh cycles
6.5.10 PC-APRV
PC-APRV (Pressure Controlled
– Airway Pressure Release Ventilation)is a v
entilation
mode in which the ventilator fully controls the ventilation. The inspiration and expiration are
pressure controlled. The inspiration time is much longer than the expiration time. The patient
can breathe spontaneously during inspiration. In general the expiration time is too short to
breath spontaneously. PC-APRV can be seen as breathing on a high CPAP level, with
mandatory short expirations induced by the ventilator in order to support CO2 elimination. The
alter nation between the two pressure levels is machine-triggered and time cycled.
The strokes are time cycled with a fixed inspiratory time and a fixed expiratory time.They are
not triggered by the patient. The patient can breathe spontaneously, but this does not influence
the cycling of the breathing phases.
