/ASB (PCV+/PS)
Biphasic Positive Airway Pressure
Assisted Spontaneous Breathing
Pressure-controlled ventilation combined with
spontaneous breathing throughout the breathing
cycle and variable pressure support at CPAP level.
For patients without spontaneous breathing, to
spontaneously breathing patients shortly before
extubation. The patient is weaned by gradually
reducing the mandatory portion of the total minute
volume MV and by reducing the pressure support
Δ
ASB.
The mandatory portion of the total minute volume
MV is set via the inspiratory pressure Pinsp, PEEP
and ventilation frequency Freq.
Refer to the description on page 129 for details.
Set the ventilation pattern with the controls below
the display:
– Frequency Freq.
– Maximum airway pressure Pmax.
–O
2 concentration O2.
The following are set on the display:
– Inspiration time Tinsp.
– Inspiratory pressure Pinsp
– Positive end expiratory pressure PEEP.
– Sensitivity Trigger.
Successful patient triggering is indicated by an
asterisk (*) in the center of the status and alarm
message window.
– Pressure rise time Ramp (effective for the
BIPAP

stroke and pressure support
Δ
ASB).
