7.4 Alarm checking procedure

Before using the ventilator, check that all critical alarms are properly adjusted according to the
ventilation parameters.

particularly prior to connection to a patient and before continuous ventilation.

Testing the mains power and external DC power alarms

Connect a patient circuit (single or double limb) fitted with a MAQUET test lung to the ventilator
and perform the manual test. Go to the clinical screens (by pressing the padlock) and set up ACV
mode, non-invasive, adult ventilation.
Turn off any alarms which may be triggered (by pressing the Alarm Silence button twice).
Perform the following test for each power supply type (mains, external DC and external battery):
