Dräger Evita 4 - Page 61

BIPAP and BIPAP/ASB can be expanded with the
following ventilation parameters:
Flowtrigger – for synchronisation with attempted
spontaneous breathing by the patient.
By setting on the flow trigger level, the mandatory strokes
are synchronised with the patient's spontaneous
breathing attempts.
Spontaneous breathing activity by the patient is indicated
by the brief display of a lung symbol instead of the usual
symbol for the patient mode.
Apnoea Ventilation – for automatic switch-over to
volume-controlled mandatory ventilation if the patient
stops breathing.
If breathing stops, Evita 4 emits an alarm after the set
alarm time (TApnoea > ) and starts volume-controlled
ventilation with the set ventilation parameters:
Frequency »fApnoea«
Tidal volume »VTApnoea«
