4.7.7 CPAP (Continuous Positive Airway Pressure)
Principle
In CPAP mode, the ventilator regulates the pressure in the airways to the set CPAP value.
The patient breathes spontaneously through the device in this mode of operation.

Continuous positive airway pressure (cmH2O)
Note:
Apnea ventilation can be activated; the apnea parameters should be suited to the con-
dition and requirements of the patient.
Note:
Loops curves, inspiratory and expiratory plateau are deactivated in CPAP mode.
4.7.8 Duo levels (Alternation of two CPAP levels)
Principle
The Duo-Levels mode is characterized by controlled-pressure ventilation, combined with the patient
having the option of breathing spontaneously throughout the entire cycle.
Duo-Levels mode enables the prescriber to maintain a constant level of pressure (PI) for a period of
time T high, then a lower level of pressure (PEEP) for a period of time T low. The duration of the high-
pressure phase can be set, as can the minimum frequency. However, in order to enable the patient’s
spontaneous breathing to properly adapt with the ventilator, there are trigger windows for synchroniz-
ing the inspiratory and expiratory phases:
•
from low pressure to high pressure, the trigger window is 60% of T low, 4 seconds maximum,
•
from high pressure to low pressure, the trigger window is 30% of T high, 2 seconds maximum. If at
the end of T high, inspiration is underway, inspiration is extended for up to 1 second.
Note:
The value of PI corresponds to the pressure added to the current PEEP value.The PEEP
value is incorporated in the PI.
