In CPAP (continuous positive airway pressure ventilation), the airway pressure is held at the
user-set positive pressure level throughout the ventilation cycle. The patient breathes
spontaneously and determines his own breathing frequency, tidal volume, and breath time.
The system starts apnea ventilation when detecting that the period of time when patient does
not perform continuous spontaneous breathing exceeds the preset apnea time.

In CPAP/PSV under non-NIV, you need to set the following ventilation parameters:
1. [O2%]: Oxygen concentration
2. [Tslope]: Time of pressure rising
3. [△Psupp]: Pressure support level
4 [PEEP]: Positive end-expiratory pressure
5. [Exp％]: Expiration trigger level
6. [ΔPapnea]: Pressure of apnea ventilation
7. [fapnea]: Frequency of apnea ventilation
8. [F-Trig] or [P-Trig]: Inspiration trigger level
9. [ATRC]: Automatic tube resistance compensation
In CPAP/PSV under NIV, you need to set the following ventilation parameters:

2. [Tslope]: Time of pressure rising
3. [△Psupp]: Pressure support level
4 [PEEP]: Positive end-expiratory pressure
