Alarm mode for the heart-lung machine HLM
HLM alarm mode can be used independently of the
active ventilation mode for patient monitoring when using
the heart-lung machine.
In HLM alarm mode,
– all apnoea alarms are deactivated.
– the gas concentrations are measured continuously
regardless of the respiratory phase.
– the SpO2 alarms are deactivated.
They are reactivated automatically when pulsations
are detected by the apparatus again after switching
off the HLM alarm mode.

● Turn the rotary knob to select the column »alarms«
and press to confirm.
● Turn the rotary knob to select the line »HLM on« and
press to confirm.
● Display (example):
The lung is kept open with constant airway pressure.
HLM alarm mode can be switched off at any time:
● Press the softkey »HLM off«.
In standby mode, the HLM alarm mode is automatically
deactivated.
