PCV Ventilation Mode
PCV = Pressure Controlled Ventilation
In pressure controlled ventilation mode, the applied
tidal volume depends on the ventilation parameters
Pmax and PEEP as well as on lung compliance.
Changes in ventilation parameters or lung compliance
influence tidal volume. Minute volume (MV or V
t
) must
therefore be monitored continuously.
Presetting ventilation parameters for PCV
1 Press »PCV«. Its LED will start flashing.
●
The five ventilation parameters for PCV appear on the
screen with their default settings.
2 Press menu key of the respective ventilation
parameter.
3 Set and confirm ventilation parameter with the dial
knob.
