Trigger (Vc-Ac); For Heart-Lung Resuscitation - Dräger Oxylog 2000 plu Instructions For Use Manual

Trigger (VC-AC)

NOTE
If in VC-CMV the trigger is set »on«, the ventilation
mode changes into VC-AC.
Refer to the previous section.
VC-AC – Volume Controlled - Assist Control
For synchronisation with the patient's spontaneous
breathing efforts.
The mandatory ventilation strokes are synchro-
nized with the patient's spontaneous breathing
efforts when the trigger is activated and the trigger
sensitivity is set.
The actual respiratory rate may be higher than the
set ventilation respiratory rate RR in this case.
The trigger can be deactivated if synchronisation
with the patient's spontaneous breathing efforts is
not desired.
Successful patient triggering is briefly indicated by
an asterisk (*) in the middle of the status and alarm
message window.

For heart-lung resuscitation

During heart-lung resuscitation, the airway pres-
sure Paw is limited to the set Pmax value by the
Oxylog 2000 plus, without ending inspiration
prematurely (pressure-limited, nonconstant-vol-
ume ventilation when Pmax is reached).
If Pmax is set to a higher value, a higher minute
volume is possible.
