EvitaXL

BIPAP, BIPAP/ASB
Biphasic 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 Pinsp above PEEP
and Frequency f.
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.
Set the pattern of ventilation for BIPAP
and BIPAP/ASB with the ventilation
parameters:
Inspiratory pressure »Pinsp«
Frequency »f«
Inspiration time »Tinsp«
O2 concentration »O2«
Positive end-expiratory pressure »PEEP«
Pressure support »PASB«
Pressure rise time »Ramp«
The inspiration pressure »Pinsp« can be
reduced to the PEEP level, in which
case the ventilation pattern corresponds
to CPAP or CPAP/ASB.
The inspiration pressure »Pinsp« is set as
an absolute value. Pressure support
»PASB« is set relative to the PEEP level.
* For a detailed description of BIPAP,
please refer to page 213.
