Leak Compensation
Use the Leak Compensation option to enable or disable tracking of the baseline flow
49
to improve
triggering when a circuit leak is present.
When Leak Compensation is on, the system is gradually adjusted to maintain set sensitivity if the leak
is stable and there is no autocycling.
• If a leak is unstable during exhalation, it will not be detected and will not be compensated for.
• Leak Compensation can compensate for a maximum patient circuit leak of 6 Lpm.
If autocycling is occurring, it can be manually eliminated as follows:
1) Set sensitivity to OFF (see Chapter 6 - Sensitivity), or higher than the leak amount (see Chapter
10 - Real Time Transducers, LEAK xx.xx Lpm).
2) Set Leak Compensation to LEAK COMP ON (see instructions below).
3) Wait for a period of 10-15 breaths.
4) Reset sensitivity to desired level (see Chapter 6 - Sensitivity).
To modify the Leak Compensation setting:
1) Push the Select button while LEAK COMP is displayed.
2) LEAK COMP ON or LEAK COMP OFF is displayed.
3) Turn the Set Value knob until the desired state is displayed.
4) Push the Select button.
Options: ON or OFF

Baseline flow is used for flow triggering detection and Vte calculation/accumulation.
