Operation
PC-BIPAP, PC-BIPAP/PS
Pressure Controlled - Biphasic Positive Airway
Pressure
Pressure-controlled ventilation combined with sponta-
neous breathing throughout the breathing cycle and va-
riable pressure support at CPAP level.
For patients without spontaneous breathing, to sponta-
neously breathing patients shortly before extubation.
The patient is weaned by gradually reducing the manda-
tory portion of the total minute volume MV and by redu-
cing the pressure support ΔPsupp.
The mandatory portion of the total minute volume MV is
set via the inspiratory pressure Pinsp, PEEP and venti-
lation respiratory rate RR.
Set the ventilation pattern with the controls below the
display:
– Respiratory rate RR.
– Maximum airway pressure Pmax.
–O
2 concentration FiO2.
The following can be set on the display:
– Positive end expiratory pressure PEEP.
– Inspiratory pressure Pinsp.
– Pressure support
Δ
Psupp above PEEP.
– Sensitivity Trigger.
Successful patient triggering is indicated by an aste-
risk (*) on the left side of the curves window.
– Ventilation time ratio I:E or inspiration time Ti.
– Pressure rise time Slope (effective for the
PC-BIPAP stroke and pressure support ΔPsupp).
– NIV - Non-invasive ventilation.
– Insp.term.%PIF
Inspiration termination criterion of pressure suppor-
ted strokes, as percentage of the peak inspiratory
flow (PIF).
– Hose type
The selected hose type must match the hose type in
use. Otherwise a correct volume measurement can-
not be guaranteed.
– Cuvette type (optional)
