The first breath of a start sequence is a
volume-controlled test breath with Pause time
set to 10%. The measured pause pressure of
this breath is then used as the pressure level
for the following breath. The pressure is
automatically regulated to deliver the pre-set
volume, but limited to 5 cmH
2
O below the set
upper pressure limit (A).
If the measured tidal volume deviates from the
preset tidal volume, the system automatically
changes the pressure level between
consecutive breaths (in steps of maximum 3
cmH
2
O) until the the preset tidal volume is
delivered.
The maximum available pressure level is 5 cm
H
2
O below the preset upper pressure limit. If
the pressure reaches this limit, the system will
deliver as much volume as possible with this
pressure. This will also trigger the alarm
'Regulation pressure limited'.
