The graph shows the currently regulated airway pressure
over time.
7.10.1 Adjustable parameters in aVCV mode
7.11 VCV mode
In VCV mode, the device triggers all breaths. You can set
fixed values for volume (Vt) and PEEP.
The graph shows the currently regulated airway pressure
over time.
7.11.1 Adjustable parameters in VCV mode
7.12 P-SIMV mode
In P-SIMV mode, it is possible to set both pressure support
for spontaneous breaths and a fixed value for the pressure
level on inspiration during mandatory breaths. In addition,
the lower pressure level is specified. The mandatory breaths
are triggered by the frequency setting.
Inspiration and exhalation phases are generally specified by
the patient’s spontaneous breathing, by the trigger
parameter, and by parameters F, Ti min, Ti max, and Ti.
The graph shows the currently regulated airway pressure
over time.
