6. Read off the pressure displayed by the mea-
surement device and enter it on the protocol in
the “Measuring result” column.
7. Read off the actual pressure displayed by the
therapy device and enter it on the protocol in
the “Mask” column.
8. Change the setting from EPAP 5 hPA to EPAP
20 hPA.
9. Read off the pressure displayed by the mea-
surement device and enter it on the protocol in

Requirement:
the values must be within the toleranc-
es quoted in the protocol.
Note

4.9 Test flow measurement
1. Connect the device output of the therapy de-
vice to the flow measurement device using the
short hose.
2. Turn on the device.
3. Prepare the VENTI motion for testing by making
the following settings in the "Physician" menu:
– T mode
– frequency f = 6/min
– Ti:T = 50 %
4. Set the two pressures so that the device dis-
plays 50 and 100 l/min in the flow window.
For example:
IPAP=10 hPa and EPAP=5 hPa
Call up the flow window by pressing the rotary
knob in the "Physician" menu during operation
and selecting “Flow curve” in the
Display
menu.
Correct the entry for pressures if necessary.
5. Enter the values displayed by the flow mea-
surement device in the protocol.
Requirement:
the values must be within the
tolerances quoted in the protocol.
6. Turn off the device.
Note
If the values are outside the tolerances, re-
place the control board (see "7.8 Replace
control board/display" on page 39).
