6.
Check the Function Selector switch
(refer to figure 1)
i)
Connect a ratePAC (510-A1541) to the Test Lung.
ii)
Connect the oxygen probe of the ventilator directly to the oxygen supply.
iii)
Turn on the oxygen supply. There should be no alarms.
iv)
Select each function in turn and check the following:
a) 0 - No output from the ventilator nor the alarms.
b) CMV+PEEP or CMV+ACTIVE PEEP - Pulsed output, times controlled by TINS and
TEXP controls and pressures controlled by Inspiratory Pressure and PEEP/CPAP
controls. The ‘cycle’ LED should flash for 1/10 second each time the pressure rises
through 10 x100Pa (10 cmH2O). The ‘single gas operation’ LED should flash to indicate
single gas selection.
c) CPAP - Constant flow output from ventilator, not cycled. Pressure controlled by
PEEP/CPAP control. No electronic alarms function during CPAP.
d) IMV+CPAP - Pulsed output as CMV, but CPAP during a longer TEXP time. No
electronic alarms function during IMV + CPAP.
v)
Check for positive switching, i.e. that there are no indeterminate mid-positions where the
function is not clearly indicated by the marking on the panel label.
vi)
Turn to ‘0’. The ventilator should stop functioning and all alarms should cease.
vii) Turn off the oxygen supply.
7.
Check calibration of Inspiratory (T
INS
) and Expiratory (T
EXP
) Time controls
7a. On Oxygen Only
(refer to Figure 3)
i)
Set Oxygen Concentration control to 100% (maximum)
ii)
Set PEEP/CPAP pressure control to minimum.
iii) Set Inspiratory Pressure control to 30 x100Pa (30 cmH
2
O).
iv) Set Pressure Alarm to 80 x100Pa (80 cmH
2
O) maximum.
v)
Turn on oxygen supply.
vi) Select CMV + PEEP. The ‘single gas operation’ LED should flash every 30 seconds and the
‘cycle’ LED should flash for 1/10 second each time the pressure rises through 10 x100Pa (10
cmH
2
O).
vii) Confirm inspiratory pressure on the Patient Pressure Manometer.
viii) Select each of the settings specified on section 12a of the Service Record Sheet.
ix)
Record the actual time for each T
INS
and T
EXP
setting in the appropriate boxes.
x)
Select IMV + CPAP and record the T
EXP
time in the appropriate box. (The electronic alarm
system does not operate during the IMV mode.)
xi) Select
‘0’.
