7.6 Check of alarm systems
Important note!
The stenosis and disconnec-
tion alarms are set off only
when the cause of the
alarm is repeated in two
successive inspiration
phases. This prevents trig-
gering of the alarm by a
very short-lived dysfunc-
tion.
Stenosis
1. Open the oxygen cylinder.
2. Remove the tube or the ventilation mask from
the patient valve.
3. Switch on MEDUMAT Standard
4. Set max. ventilation pressure regulator at
60 mbar.
Important note!
In this test the rise in pres-
sure is strong enough to
make the manometer nee-
dle overswing considera-
bly. There are technical
reasons for this and it does
not indicate any malfunc-
tion.
5. Keep the ventilation connector on the patient
valve closed with the flat of your hand during
two successive inspiration phases. The
Stenosis
alarm should be set off.
Interruption of breathing system
(Disconnection)
1. First proceed as for the Stenosis alarm.
2. Then remove your hand. The
Stenosis alarm
should cease (LED stops flashing, acoustic alarm
stops sounding).
After two successive inspiration phases the
Disconnection alarm should be set off.
Drop in O

pressure (< 2,7 bar O

)
1. Open the valve of the oxygen cylinder slowly.
2. Switch on MEDUMAT Standard.
3. Close the valve on the oxygen cylinder. When
the oxygen pressure in the system has sunk be-
low 2.7 bar, the
< 2,7 bar O

alarm should be set
off.
