Newbie Question about mask alarms

My mom has been wearing a Bipap machine for about 8-9 nights. Quite similar to CPAP machines but contains an oxygen bleed line, as well. She is wearing it because of IPF; needs to be blowing off the CO2 that she builds up during the day.

Trouble is, she seems to knock the mask off while sleeping. Ergo, might be going a number of hours without the Bipap and without her oxygen line. I realize it takes time to adjust to wearing the mask. However, she is 81 and it's just not good for her to be without oxygen for too long.

My question: does any manufacturer of machine/mask (or even a reputable 3rd party) make an alarm that would alert her and/or others in the house that mask has been removed?

Current machine & mask specs in case this helps. bipap machine: manufacturer: ResMed model: AirCurve 10 VAuto Serial number: 23171006661

current mask: mask manufacturer: ResMed mask model: AirFit F20

Thanks very much, in advance, for any advice or suggestions.

I have not had my hands on that specific model yet, but I can tell you that, historically, ResMed do put alarms in their machines for exactly that situation. If your specific model doesn't have the capability I can assure you that some do. ResMed even has a range with extra alarms (the VPAP ST-A), but a mask fit alarm or high leak alarm is fairly standard. Ask someone (preferably an experienced technician) to look at your settings and see if there is some sort of leak alarm that can be turned on.

I use the Aircurve 10 and there are no alarms for leaks or otherwise and I have been through the backend settings somewhat. I will say that the machine has changed a tad over the years with minor differences so I can't speak to this for sure.
