Verify that:
The visual and audible Apnoea alarm
is triggered after 20 seconds.
Step 7 Pull the test lung to mimic a breath, then acknowledge and reset the alarm.
Verify that:
a manual breath is delivered when the manual breath button is
pressed.
Step 8 Set the High alarm Threshold to 35mbar.
Step 9 Gently constrict the proximal airway tube so as to increase the pressure. Allow
the pressure to increase but do not allow it to exceed the High alarm threshold.
(This can be achieved by releasing the constriction of the proximal airway tube by
a small amount.)
Do not reset any Apnoea alarms that may be generated.
Verify that:
after 10 seconds the continuing
positive pressure alarm is triggered
and that the fresh gas supply is cut off.
When the gas supply is cut off release
the constriction from the proximal
airway tube.
After 6 seconds the fresh gas supply should be re-instated.
Step 10 Press the reset button in the alarm panel to clear all alarm notifications.
