The value for the ventilation parameter T
automatically turns yellow and is adjusted at the

remains constant.
Changes in PEEP
Depending on the configuration, the pressure limit
value P
can also be changed automatically

The value for the ventilation parameter P
automatically turns yellow and is adjusted at the
