7.2 Flow Valve Leak Alarm

The eAdvantage® system includes a fl ow valve leak detection feature that
functions when the unit is supplied with gas.
While the device is ON, it continually monitors the outputs from both fl ow
sensors. This monitoring occurs during the standby mode or for 10 seconds
following the last patient-demanded breath.
If either of the fl ow sensors detects any unexpected fl ow (suggestive of a leak),
the device will promptly display leak alarms on the screen, alerting the user to
the issue.
Note: It's important to note that the leak detection feature will be inactive when
both input gases are turned OFF (0 PSI). This means the detection feature only
operates when there is gas pressure present in the system.
