5. Checking the supply pressure alarm
6. Checking the ventilation rate
Information: In combination with the testing bag, these settings
can cause the pAW /apnea alarm to be triggered. The alarm can be
ignored during this test step.
The number of mechanical breaths within one minute is between
23breaths per minute and 27breaths per minute.
Select the following settings:
Via the adjusting knob:
Vt = 65 ml |Freq. = 25 bpm
Via pMax button with control LEDs:
pMax = 45mbar
After the oxygen cylinder has been closed, the visual and audible
alarm for <2.7bar O2is triggered once the device supply pressure falls
below 2.7 bar O2.
The <2.7bar O2 alarm stops when there is sufcient supply pressure.

23-27bpm

7. Checking the tidal volume and pAW alarm
The LEDs on the ventilation pressure display light up to
40mbar–45mbar.
Select the following settings:
Via the adjusting knob:
Vt = 950 ml | Freq. = 10 bpm
Via pMax button with control LEDs:
pMax = 45 mbar
The device triggers the pAW alarm after the thirdmechanical breath
at 40mbar–50mbar without simulated expiration.
After the manually simulated expiration (depress the testing bag with
your hand at and then release again), the device rells the testing bag
completely.
Information: In combination with the testing bag, these settings can
cause the pAW alarm to be triggered. The alarm can be ignored
during this test step.

8. Checking the pAW /apnea alarm
The device triggers the pAW /apnea alarm after the second
mechanical breath.
9. Checking MEDUtrigger
Select the following settings:
Via the adjusting knob:
Vt = 950 ml | Freq. = 10 bpm
Via pMax button with control LEDs:
pMax = 45 mbar
The Manual button and the LEDs on MEDUtrigger light up.
