ation of the patient by a heart lung machine (HLM).
In HLM mode:

ently of the breathing phase.
–CO
2 apnea and pressure apnea alarms are in-
active.
–SpO
2 monitoring alarms are inactive.
–The MAC LOW? alarm is inactive.
– MV alarms and flow apnea monitoring can be
configured (see page 171).
The HLM mode can be used in all active ventilation
modes.

To activate/deactivate HLM mode in an active ven-
tilation mode:
1 Press the soft key config. (A) on the standard
or data screen. The submenu volumes/ alarms
is opened.

vated when pulse signals have been detected
again.

set is retained.
