Technical data
Demandflow
An inspiration impulse (trigger) at V2 opens valves
V3 and V4.
Electronic system
The microprocessor-controlled electronic system sets
the ventilation parameters and monitors ventilation,
and also O
visual and acoustic alarm is given. The ventilator has
an audio response facility that can be switched on
for user guidance.
The following diagram shows the relationship be-
tween the ventilation parameters "tidal volume"
and "respiratory frequency":
