PC-BIPAP, PC-BIPAP/PS
PC-BIPAP
Pressure Controlled – Biphasic Positive Airway
Pressure
Pressure-controlled ventilation combined with
spontaneous breathing throughout the respiratory
cycle and variable Pressure Support at CPAP level.
For patients without spontaneous breathing and
spontaneously breathing patients until 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 ΔPsupp.
The mandatory portion of the total minute volume
MV is set via the inspiratory pressure Pinsp, the
positive end-expiratory pressure PEEP and the
respiratory rate RR.
Refer to the description on page 157 for details.
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
– Trigger sensitivity
Successful triggering by the patient is indicated
by an asterisk (*) on the left side of the curve
window.
– Ventilation time ratio I:E or inspiratory time Ti
– Pressure rise time Slope (effective for the
PC-BIPAP breath and the pressure support
Δ
Psupp)
– NIV – non-invasive ventilation
See "Non-invasive ventilation (NIV)" on
page 75.
