A stenosis can also cause the filling time of the lungs to 
become longer than the set inspiration time T

insp

.

Starting behavior of AutoFlow

Upon switching on the function AutoFlow Savina applies 
the set tidal volume V

T

 using a volume-controlled breathing 

stroke.
The plateau pressure Pplat derived from this breathing stroke 
serves the function AutoFlow as starting value for the 
inspiration pressure.

Settings to suit the patient’s needs

The Start of the mandatory inspiration can be synchronized 
with the patient’s inhalation effort with the help of the variable 
flow trigger. The flow trigger can only be completely turned off 
in IPPV (IPPVAssist –

>

 IPPV).

The steepness of the pressure increase from PEEP level to the 
inspiration level can further be adapted with the ventilation 
parameter FlowAcc in SIMV and IPPV to suit the patient’s 
needs.
