alarm setting for 10 seconds in active therapy.
What to do
•
Confirm proper connection of the oxygen source.
• When using low-flow oxygen, check for unnecessary leaks. Increase flow rate if possible.
• When using high pressure oxygen, check for excessive leaks.
• If the alarm persists, calibrate the oxygen sensor. See “chapter 7, Device Options.”

Algorithm
summary
Because the inlet filter is blocked, the pressure generated by the ventilator is less than 75% of the
estimated outlet pressure based on the nominal performance characteristics of the device.
