Instructions for Use Oxylog 3000 SW 1.n
Using BIPAP
®
As with SIMV, the time pattern is set using the basic
setting parameters of frequency Freq. and
inspiration time Tinsp. The lower pressure level is
set with the PEEP parameter, while the upper level
is set with Pinsp.
When switching over from IPPV to BIPAP
®
mode,
note that the inspiration time Tinsp is set, instead of
the ventilation time ratio I:E.
When switching over from SIMV to BIPAP
®
mode –
while retaining the time pattern – only the Pinsp
setting needs to be changed.
The steepness of the increase from the lower
pressure level to the upper pressure level is
controlled by the Ramp setting.
During the lower pressure level phase,
spontaneous breathing can be assisted by ASB.
The steepness of the pressure increase to ASB
pressure ΔPASB above PEEP is also controlled by
the Ramp setting.
The transition from controlled ventilation via the
weaning phase to fully spontaneous breathing is
achieved by a gradual reduction of inspiratory
pressure Pinsp and/or frequency Freq.
