Main Flow
1.
Remove the test lung from the patient circuit Y-piece.
2.
Place the calibration analyzer at the inhalation outlet.
3.
Set the calibration analyzer to flow measurement.
4.
Press the button under the Tidal Volume window.
5.
Use the touch-turn-accept method to adjust setting to 2.00 L.
6.
To choose Flow , press the Select button at the top of the Flow/t Insp window.
7.
Press the Main Screen button on control panel.
8.
To display the numeric data, touch the Numeric button on the screen.

Note:
When the Insp Flow reading displayed on the Numeric screen is higher than expected flow, it could be
caused by the peak flow delivered in the very beginning of the inspiratory phase. In this case, select
Flow Wave on the Extended Functions screen, and then touch the Freeze button to read the actual flow
value. To adjust the scale of the waveform, touch the flow axis on the screen, turn the adjustment knob
to obtain a proper scale, and then touch the flow axis again to accept the change.
9.
Set Flow to 5 L/min.
10.
Verify that the value of Insp Flow displayed on the Numeric screen, the flow reading measured by the
calibration analyzer, and the flow setting are within ± 1L/min of each other. Document the results on the
record sheet.

Note:
The flow reading measured by the calibration analyzer mentioned in steps 10 through 16 is the actual
delivered measurement divided by 89%. This is because the ventilator automatically reduces the flow
delivery by 11% of the set flow to compensate for humidifier use (BTPS compensation).
11.
Set Flow to 10 L/min.
12.
Verify that the value of Insp Flow displayed on the Numeric screen, the flow reading measured by the
calibration analyzer, and the flow setting are within ±1 L/min of each other. Document the results on the
record sheet.
13.
Set Flow to 50 L/min.
14.
Verify that the value of Insp Flow displayed on the Numeric screen, the flow reading measured by the
calibration analyzer, and the flow setting are within ±4 L/min of each other. Document the results on the
record sheet.
15.
Set Flow to 80 L/min.
