NOTE: The gas source(s) must be capable of maintaining a pressure of at least 305 kPa (
≈
3 bar)
whilst delivering a flow of 20 L/min.
3.
If connected to a cylinder regulator(s) turn on cylinder valve(s) slowly .
4.
Check that the visual alarm(s) for supply gas failure have changed from red to white
(oxygen) or black and white (air).
5.
Switch the function selection switch to ‘CMV+PEEP’ or ‘CMV+ACTIVE PEEP’. The
ventilator should commence cycling and all the alarm lights flash in turn. A single burst of
the high priority audible alarm is given at the same time. The orange silenced indicator
should flash for 60 seconds. Check that flow is coming from the patient connection port by
feeling the flow when placed close to the back of the hand or to the face.
6.
Occlude the proximal connection port of the patient circuit and check that the manometer
gives a reading of between 15 and 25 x100Pa (15 and 25 cmH
2
O) during each inspiratory
phase. The audible alarm should not sound.
7.
Leaving the high pressure alarm setting at 30 x100Pa (30 cmH
2
O) set the inspiratory
pressure to 40 x100Pa (40 cmH
2
O). When the proximal connection port of the patient
circuit is now occluded the pneumatic audible alarm should also sound, accompanied by the
high inflation pressure visual alarm. The manometer should read between 25 and 35 x100Pa
(25 and 35 cmH
2
O). After occlusion for one second, once the silencing period has elapsed,
the high priority electronic audible alarm will also sound. Check that the unit cycles
regularly about every 3 seconds.
NOTE: After the 60 second initial silenced period the electronic audible alarm will operate if an
alarm condition persists. This sound can be silenced for 60 seconds by a single depression
of the silencing button. If the alarm condition continues beyond this silencing period, a
second depression of the button will be interpreted as an acknowledgment by the operator
that the condition is continuous and so the audible alarm for that function is muted.
8.
Allow the ventilator to cycle with no obstruction at the output port and check that the low
inflation pressure (disconnect) alarm operates after 8 seconds.
9.
Set the T
I
and T
E
and knobs to the extremes of their range. By listening to the gas flow,
check that the ventilator is responding to the controls and that no irregularities of
performance can be discerned.
10.
If an oxygen analyser is available the oxygen concentration can be checked at typical
settings by connecting the sensor into a tube connected to the patient port at one end and
flowing to atmosphere at the other.
11.
To check the CPAP function, select CPAP on the function selector switch. Turn the CPAP
control clockwise to the first click of the tactile warning range and then occlude the
proximal connection port. The pressure manometer should indicate between 6 and 14
x100Pa (6 and 14 cmH
2
O).
12. To check the IMV function, select IMV+CPAP on the function selector switch and set the
expiratory time to 1.0 second. The expiratory time should be measured as approximately 10
seconds.
