6.3.6 MAIN PCA OXYGEN VERIFICATION (OPI UNITS ONLY)
This procedure verifies that the Main PCA is operating properly.
1. Plug the unit into a power outlet.
2. Turn the device on, set the flow to 5.0 LPM, and let it run for 10 minutes.
3. If either the yellow or red LED illuminates after 10 minutes, perform the oxygen output test with a
calibrated oxygen analyzer. If the red LED illuminates, the audible alarm should also sound at the
same time.
The oxygen analyzer used in the following steps must be calibrated to meet the
manufacturer's specifications.
If the device is alarming and the oxygen concentration is measured at 82% or higher, check the device for leaks.
If no leaks are found then replace the Main PCA.
