Ventilation mode Volume Control Auto-
Flow
Volume Control AutoFlow with decelerating inspira-
tion flow
Fixed mandatory minute volume MV adjusted with
tidal volume VT and respiratory rate RR.
For patients with and without spontaneous breath-
ing.
The patient can breathe spontaneously at any time
(free deep breathing ability). Spontaneous breath-
ing can be supported with Pressure Support.
Adjust volume-controlled ventilation with autoflow,
synchronization, synchronization/Psupp:
A Maximum airway pressure P
max
B Tidal volume VT
C Respiratory rate RR
D Positive end-expiratory pressure PEEP
E Switching synchronization on and off Sync.
Switching on provides synchronization and, if
set, activation of the set pressure support.
F Flow trigger threshold Trigger for synchroniza-
tion of mandatory breath
An exceeded trigger threshold is represented in
the pressure curve by triangles.
G Pressure support

H Inspiration time T

WARNING
Risk of patient injury
Do not use Volume Control AutoFlow
ventila-
tion mode with intrinsic PEEP (alarm mes-
sage: Exp. time too short). Expiratory flow
does not return to the base line. This can
cause an excessive pressure rise in ventila-
tion pressure.
CAUTION
The administered volume may be lower than the
set volume if there is a leak!
