Operation
BIPAP-SIMV
Combination of timecycled,
pressure controlled
ventilation with spontaneous breathing.'
The patient can breathe spontaneously and receives
intermittent, pressure controlled ventilation strokes at a
frequency which corresponds to the WV-frequency
set.
In contrast to SIMV the ventilation strokes are not volu-
me-constant, and spontaneous breathing is possible at
the upper pressure level.
The duration of the pressure controlled ventilation strokes
is determined by the parameters of the basic settings:
frequency f
ratio TI:TE
The inspiratory pressure is determined by the parameter
p&P.
An automatically-adjusted
trigger window always allows
the pressure controlled strokes to be synchronised
without increasing IMV-frequency.
