4.8.10 CPAP

Positive continuous pressure applied on the airway.
•
The system displays all PRP relative to the set
operating mode.
CPAP is a spontaneous positive pressure ventilation at continuous flow.
In this operating mode the patient is free to breath spontaneously inside the circuit but at a
pressure greater than the atmospheric one, with increased residual functional capacity.
During spontaneous breathing the pressure value varies around the set value, it tends to
drop when the patient inhales and to rise when the patient exhales.
During the Apnea Back-up activation (in APCV ventilation), if you push the ALARM
RESET button only the acoustic alarm is silenced. Then, the system will come back to
CPAP ventilation only when the patient will be able to breath spontaneously.

WARNING !! Patient injury hazard
If the patient does not trigger (spontaneous breathing during the apnea time
set in MAIN MENU - SETUP), the system activates the APNEA acoustic
and visual alarm.
The system will automatically provide an APCV ventilation with set, safety
respiratory rate (RR bk), I:E ratio (I:E bk) and inspiratory pressure (Pinsp
bk).
