7.8.1 Adjustable parameters in aPCV mode
7.9 PCV mode
In PCV mode, the device triggers all breaths. You can set
fixed values for the IPAP and PEEP pressure levels.
The graph shows the currently regulated airway pressure
over time.
7.9.1 Adjustable parameters in PCV mode
7.10 aVCV mode
In aVCV mode, fixed values can be set for volume (Vt) during
inspiration and for the lower pressure level during
exhalation.
In aVCV mode, the device supports the patient in his or her
ventilation, the patient can trigger on inspiration. Both the
patient’s spontaneous breathing and the mechanical breaths
triggered by the device may predominate.
