Perform The Pre-Use Test; Actions At Pre-Use Test Failure - Breas VIVO 65 User Manual

Inspection before Use
Always make the following checks before using the Vivo 65:
1. Connect a patient circuit to the Vivo 65.
2. Connect the Vivo 65 to the AC power (Mains) supply.
3. Turn on the Vivo 65 main power using the Standby button on the side panel.
4. Ensure that the treatment settings and alarm settings are adjusted as prescribed, and that
the correct patient circuit type is selected.
5. Perform a pre-use test by following the instructions on the display.
Note: Pre-use test cannot be performed in MPV breath mode. Skip this step if MPV
breath mode is used.
6. Press the Start/Stop button on the front panel until the progress bar is filled.
7. Check that a short double sound signal is heard. If there is no signal, do not use the
Vivo 65 and contact your service provider.
8. Disconnect the power cord for more than 5 seconds. Check that the device switches to
the internal battery (or click-on battery if connected) and that an information message is
shown on the screen together with an audible warning. If this is not the case, contact
your service provider.
9. Reconnect the power cord. Check that the device switches to the AC power (Mains) sup-
ply and that an information message is shown on the screen together with an audible
warning.
10. Connect the patient and adjust and fit the mask if one is used.

Perform the Pre-Use Test

The pre-use test is used for detecting the type and characteristics of the patient circuit that is
connected to the Vivo 65. The resistance and compliance of the patient circuit are measured
and calculated. This will be used to compensate for pressure and compliance deviations dur-
ing treatment.
The patient shall not be connected during the pre-use test.
CAUTION!
Always perform a new pre-use test if the patient circuit configuration or insert has been
changed.
NOTE
If the pre-use test has not been performed, the Vivo 65 will operate with default patient
circuit compensation.
Pre-use test cannot be performed in MPV breath mode.
