Pressure-controlled assist/control venti (PC-ACV+) 7.3.2.7
The PC-ACV+ corresponds to the behavior of the PC-ACV. The
expiration trigger is active in this mode.
The change to the PEEP level takes place either upon expiration of the set
inspiration time or is patient triggered at incipient expiration by the
patient. As a result, the patient controls the beginning, progress, and
volume of the mechanically supported breath.

Non-invasive pressure-controlled assist/control ventilation plus 7.3.2.8
(nPC-ACV+)
The nPC-ACV+ corresponds to the behavior of the PC-ACV. It is only
available in non-invasive Neo mode. The expiration trigger is active in
this mode (see chapter 7.2). If the device is operated without a flow
sensor (PNT), pressure is measured proximally via the pressure
measurement adapter set.
The change to the PEEP level takes place either upon expiration of the set
inspiration time or is patient triggered at incipient expiration by the
patient. As a result, the patient controls the beginning, progress, and
volume of the mechanically supported breath.
