BIPAP
Assist
Biphasic Positive Airway Pressure Assisted
Druckkontrollierte, assistierende Beatmung
The inspiratory strokes are the same as for BIPAP, but the
changeover from P
insp to PEEP is not synchronised with
expiration by the patient. The patient can breathe
spontaneously at PEEP level through the entire ventilation
process.
Every spontaneous breathing activity by the patient triggers a
synchronised inspiratory stroke.
A non-synchronised inspiratory stroke is started by the device
at the latest upon expiry of the time »f«.
For all patients, from those unable to breathe spontaneously to
those breathing spontaneously before being weaned off the
ventilator.
The set values for the relevant ventilation parameters are
displayed alongside the keys for the ventilation parameters.
Set the ventilation pattern for BIPAP
Assist via the keys for the
ventilation parameters:
Inspiratory pressure »P
insp«
Frequency »f«
Inspiration time »T
insp«
Sensitivity »Trigger«
O
2 concentration »O2«
Positive end-expiratory pressure »PEEP«
Pressure rise time »Ramp«
Absolute inspiratory pressure »P
insp«

To activate:
● Press menu button »other modes«.
When BIPAP
Assist has been selected in the menu with the
cursor:
● Hold the menu button »other modes« for approx.
3 seconds,
or:
