7.7.1 Adjustable values in PSV mode
7.8 aPCV mode
In aPCV mode, fixed values can be set for the pressure levels
during inspiration and exhalation. In aPCV 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.
The graph shows the currently regulated airway pressure
over time.

Rate
2 – 60/min
Set background frequency (rate) per minute here.
Ti min
0.5 s – Ti max
Set the minimum duration of inspiration for spontaneous
breaths here.
Ti max
0.5 s – 4 s
Set the maximum duration of inspiration for spontaneous
breaths here.
Ti timed
Auto
0.5 s – 4 s
Set the duration of inspiration for mandatory breaths here.
On Auto setting, the Ti min and Ti max limits also apply to the
inspiration times during background ventilation.
