Operation
Setting Ventilation Modes
BIPAP, BIPAP/ASB
Biphasic Intermittent Positive Airway Pressure
Assisted Spontaneous Breathing
Pressure-controlled ventilation combined with free
spontaneous breathing during the complete breathing
cycle, and adjustable pressure support at CPAP level.
The mandatory proportion of the total minute volume MV
is set with inspiratory pressure P
Frequency f.
For a range of patients, from those unable to breathe
spontaneously to those breathing spontaneously before
extubation. Patients are weaned off the ventilator by
progressive reduction of the mandatory proportion of the
overall minute volume MV and reduction of the pressure
support P
.
ASB
The frequency can be reduced to 0 during the weaning
process. The device automatically changes to the
ventilation mode CPAP or CPAP/ASB. This ventilation
mode is also indicated on the screen.
The screen key »BIPAP« and the screen knobs for setting
the BIPAP parameters remain on display.
