BIPAP, BIPAP/ASB (Optional)
Biphasic Positive Airway Pressure
Assisted Spontaneous Breathing
Pressure-controlled ventilation combined with free
spontaneous breathing during the complete breathing cycle,
supported by adjustable additional pressure at CPAP level.
The mandatory proportion of the total minute volume MV is
set by means of the inspiration pressure Pinsp, PEEP and
frequency f.
Adaptable to a wide range of patients, from those unable to
breathe spontaneously at all to those breathing spontaneously
before extubation. Suitable for weaning patients from artificial
ventilation by progressively reducing the mandatory fraction of
the minute volume MV and by reducing the additional artificial
pressure support ∆ PASB above PEEP.
For details see "BIPAP" description, page 104.
Set BIPAP by means of the ventilation parameter keys:
— Inspiration time »Tinsp«,
— Frequency »f«,
—O2 concentration »O2«,
— Inspiration pressure »Pinsp«,
— Positive end-expiratory pressure »PEEP«.
The following can be set on the screen:
— Sensitivity »Trigger« (for synchronization with spontaneous
breathing)
To set the trigger, page 23
— FlowAcc
can be set on screen on screen page
»Settings 1/1«.
FlowAcc is effective both for BIPAP strokes and pressure
support »∆ PASB above PEEP«
— Additionally for BIPAP/ASB:
Pressure support »∆ PASB above PEEP«
BIPAP, BIPAP/ASB can be supplemented with apnoea
ventilation:
● To set apnoea ventilation, see page 28.
● To set alarm limits, see page 30.
