System Final Test (Continued)
Step 5 Verify the compensated total flow values are within specification.
Step 6 Set the flow restrictor for 10, 60, and 120 LPM (± 1 LPM) and repeat steps 3-5.
Step 7 While at 120 LPM, verify the pressure is 20 cm H
G. Dynamic Pressure Regulation
Step 1 Turn the unit Off.
Step 2 Disconnect the flow restrictor from the flow meter.
NOTE: The test lung should not be connected at this time.
Step 3 Connect a whisper swivel to the patient tubing at the output of the flow meter and plug
the end. Turn the unit On. Wait for the Test Exhalation Port Screen to appear.
Step 4 Press Test Exh Port then Start Test. Follow the on screen instructions as appropriate until
"TEST COMPLETE" is displayed.
NOTE: Do not block the slots on the Whisper Swivel while the Exhalation Port Test is in
progress.
Step 5 Press MONITORING to exit then press PARAMETERS.
Step 6 Ensure that the unit is still in CPAP mode, set at 20 cm H
Step 7 Remove the plug and connect the test lung. (Compliance set to 0.05, Parabolic Resistor
RP 20). See Figure 8-7 for setup instructions.
Step 8 Press MONITORING and verify that the unit is in "Waveform" display.
Step 9 Manually operate the test lung to create a uniform waveform on the Vision flow display
with peaks approaching 100 L/Min and a rate of approximately 30 BPM (one every two
seconds). While doing this, observe the manometer reading.
Step 10 Verify the manometer reading to be within ± 2 cm H
