WARNING
Risk of patient injury
If the ventilator and the fresh-gas delivery fail,
the anesthesia machine switches to the venti-
lation mode Monitoring and discontinues the
fresh-gas flow automatically.
An O
2 flow must be delivered to the patient
and the patient must be ventilated manually.
Check the vaporizer setting, open the Safety
O
2 control, set a sufficient flow, set the APL
valve to an adequate pressure limiting value,
and ventilate the patient manually.
WARNING
Risk of patient injury
If pressure and volume monitoring fails, the
patient cannot be adequately monitored.
Ensure adequate substitute monitoring!
