In the Bi-Vent mode the ventilator uses two
shifting pressure levels, with the patient being
able to breathe spontaneously on both these
levels.
Since Bi-Vent is basically a controlled mode
of ventilation, apnea alarm and backup
ventilation are not available. It is also very
important to set lower and upper alarm limit
for expired Minute Volume.
Every Bi-Vent cycle is regarded as
autonomous and therefore most of the
measured values are updated every Bi-Vent
cycle, i.e. minute volumes, respiratory rate,
mean pressure and end expiratory pressure.
In accordance to this, associated alarms are
also handled for every Bi-Vent cycle.
At extreme settings the update of measured
values and alarms will show a mandatory
frequency dependence even in the face of
preserved spontaneous breathing.
As a result of switching between two different
pressure levels, the tidal volumes may vary
significantly between different breaths. This
may also be the case for etCO
2
concentration.
It is not recommended to use Auto scale in
Bi-Vent mode, when the patient is breathing
spontaneously on both levels.
