Leak Test
A leak test is available for times when you want to perform only a leak test and not complete an entire circuit calibration.
Prerequisites:
• Ensure the prescription is for an active circuit:
- Active Flow
- Active PAP
- Dual Limb
• Remove the patient interface from the circuit.
• Block the end of the circuit where the patient interface would be.
• If the circuit includes a heated humidifier, ensure the humidifier chamber is filled.
• Ensure the external active exhalation valve is properly assembled and connected.
To perform a leak test:
1. In the menu bar, tap the Options icon.
In the Options window, tap Calibration and Setup.
2. In the Calibration & Setup window, tap Leak Test.
3. Review the prerequisites and then tap Start.
4. The system performs the test. The results appear in the test progress pane. If the test:
• Fails: Review the failure reasons. If you want to try again, tap Retest; otherwise, tap the cancel button at the
top of the window.
•
Passes: tap OK.

Sensor Calibration
Prerequisites:
• Ensure the patient circuit is connected.
• Remove the patient interface from the circuit.
• Remove any passive exhalation device.
• Connect high-pressure O

.
• Ensure that low-flow O
2
is not connected.
To calibrate the O
2
sensor:
1. In the menu bar, tap the Options icon.
2. In the Options window, tap Calibration and Setup.
3. In the Calibration & Setup window, tap O

Sensor Calibration.
4. Review the prerequisites and then tap Start.
5. The system performs the Circuit Flush test. The results appear in the progress pane. If the test:
• Fails: Review the failure reasons. If you want to try again, tap Retest; otherwise, tap Quit.
•
Passes: go to the next step.
6. Block the end of the circuit and then tap Continue.
7. The system performs the 21% Calibration test. The results appear in the progress pane. If the test:
• Fails: Review the failure reasons. If you want to try again, tap Retest; otherwise, tap Quit.
• Passes: go to the next step.
8. If you are using an oxygen-blending module, confirm that high-pressure O
2
is connected and the circuit outlet is blocked
and then tap Continue. Otherwise, the test is complete.
