In PRVC-SIMV mode, you need to set the following basic ventilation parameters:
1. [O
2
%]: Oxygen concentration
2. [TV]: Tidal volume
3. [Tinsp]: Inspiration time
4. [fsimv]: Mandatory breathing frequency
5. [ΔPsupp]: Pressure support level
6 [PEEP]: Positive end-expiratory pressure
7. [F-Trig] or [P-Trig]: Inspiration trigger level
8. [Exp%]: Expiration trigger level
9. [Tslope]: Time of pressure rising
10. [Apnea Ventilation]: Switch for apnea ventilation
11. [TVapnea] or [ΔPapnea]: Tidal volume or inspiration pressure in apnea ventilation
cycle
12. [fapnea]: Frequency of apnea ventilation
13. [Apnea Tinsp]: Inspiration time of apnea ventilation
