I use F&P masks with my ResMed machine. If I have the "pillows" setting on the machine will automatically shut off when I remove the mask. It doesn't matter if I am using a pillow mask or a nasal mask the machine will shut off as it should. If the setting is nasal, the machine doesn't shut off. This wasn't always the case.

My smart start/stop has started working again. I switched mask types, from a nostril mask to a nasal pillow and changed the setting on the machine. It still wasn't shutting off until I switched masks while the machine was on. Normally I take the mask off my face. In the middle of the night I removed the mask from the tube while the machine was running, and before I could attach the other mask the machine turned off on its own. The next morning I removed my mask as usual and after a few seconds smart start turned the machine off. For some reason, now it is working as it should.

I don't understand what changed has taken place that the machine understands I am no longer wearing the mask and shuts itself off.

It is working as it should.

Okay, thank you. If I take a nap during the day I usually don't put water in the tank.

I get 0 often enough, and readings under 1.0 most of the time. The machine is in CPAP mode.

If I don't use the CPAP I will snore, and wake up with headaches. If I do use it, I have low readings.

It might be time to get a new machine.

If you are good with repairing electronics, and can find the part number for the defective part you can search for that. If you can't fix it yourself I don't know.
Some people won't fix medical equipment, but your laws may vary.

Ask your doctor to look at the data on the machine. You might not have a high enough pressure.

What brand of machine do you use?

What CPAP did you say you use? How do you turn the humidifier off?
With my old F&P, the airplane mode turned off the humidifier, with the AirSense 10 the water basin still gets warm, and the heat indicator lights on the display in Airplane mode.

Any of the searching I have done on this shows that it has been a long-standing problem. The sensor probably wears out.

I am wondering if it is because of a software update.

I use Fisher & Paykel masks, they come with a cloth or cotton defuser. I disliked the Resmed masks because of the open vents,
