8.7 Checking the alarm systems
Important
In the case of the stenosis
alarm and the disconnec-
tion alarm, the alarm signal
(or message) is only set off
when the cause of the
alarm is repeated in two
successive inspiration
phases. This prevents the
alarm being triggered by a
very short-lived dysfunc-
tion.
Important
In this test the rise in pres-
sure is so strong that the
pressure gauge needle may
overswing into the red
zone. There are technical
reasons for this, and it does
not indicate any malfunc-
tion.

6. The MEDUMAT Easy switches the flow on and
then immediately off again. This test can be re-
peated several times.
7. Switch off MEDUMAT Easy again.
Stenosis
1. Open the oxygen cylinder.
2. Remove the tube or the ventilation mask from
the patient valve.
3. Switch on MEDUMAT Easy.
4. Switch the mask/tube switch to
5. Keep the ventilation connector on the patient
valve closed with the flat of your hand during
two successive inspiration phases. The
alarm should be set off.
If audio response is enabled, the ventilator an-
nounces "Check airways and minute volume"
(from serial number 8000 and following repair/
servicing/ firmware update: "Check airways and
settings").
Disconnection (interruption of breath-
ing system)
1. First proceed as for the
