8. Check calibration of PEEP & CPAP Pressure control
(refer to Figure 4)
i) Connect a calibrated 0-100 x100Pa (0-100 cmH
2
O) pressure gauge (e.g. 500-82802/2) to the
Test Lung.
ii) Set T
INS
and T
EXP
at 0.5 secs
iii) Set Pressure Alarm at 80 x100Pa (80 cmH
2
O).
iv) Set Inspiratory Pressure at 70 x100Pa (70 cmH
2
O).
v) 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).
vi) Check & record minimum, detent & maximum PEEP on both the calibrated gauge and the
Patient Pressure Manometer. When the PEEP level is greater than 10 x100kPa (10 cmH
2
O)
for longer than 8 seconds, the ‘cycle’ LED will not indicate but after 8 seconds the Constant
Positive Inflation Pressure alarm should activate (see Figure 2). The ‘high inflation pressure’
LED should flash 2 times per second and a high priority audible alarm should sound,
consisting of two bursts of five pulses at a rate of 6 times per minute.
vii) Depress the ‘silence’ button and the electronic audible alarm should silence for 60 seconds.
After this 60-second period has elapsed, depress the button again and the audible alarm should
now remain muted. The ‘single gas operation’ LED will continue to indicate.
viii) Select CMV+ACTIVE PEEP.
ix) Check & record minimum, detent & maximum ACTIVE PEEP on both calibrated gauge and
Patient Pressure Manometer.
x) Select CPAP. During CPAP no alarm should operate.
xi) Check & record minimum, detent and maximum CPAP on both the calibrated gauge and the
Patient Pressure Manometer.
xii) The difference between the calibrated gauge and the Patient Pressure Manometer should be no
more than 2 x100Pa (2 cmH
2
O).
xiii) Select ‘0’.
9. Check calibration of Inspiratory Pressure control
(refer to Figure 4)
i) Select CMV+ PEEP. The ‘single gas operation’ LED should flash and the ‘cycle’ LED should
flash each cycle.
ii) Set T
INS
at 2.0 seconds.
iii) Set Pressure Alarm at 80 x100Pa (80 cmH
2
O).
iv) Set PEEP/CPAP control to minimum.
v)
Set the Inspiratory Pressure successively to minimum, 20 x100Pa (20 cmH
2
O), detent and
maximum inspiratory pressures and record the readings on both the calibrated gauge and the
Patient Pressure Manometer at each setting.
vi) Select ‘0’.
vii) Reconnect the air supply to the ventilator.
viii) Turn on the air supply.
ix) Select CMV + PEEP. The ‘cycle’ LED should flash.
x) Repeat v) above.
