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
2
.
•
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

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.
