Question for oxygen users

I require oxygen when I use my cpap. Because that concentrator
makes a lot of noise I have it in another room. I hate to say it but
sometimes I may lay down for a short nap with my cpap and fail
to turn the oxygen on. Anyone come up with a solution to this. Oh
I found a remote power on switch but if I use it I have to leave the
switch on the O2 concentrator always on and when I switch it off
by remote the unit will think there was a power failure and beep .
I don't think of an easy fix for this but thought I might ask.

Do the same process every time you lie down and after several times you will not forget. Don't skip the process. Don't make exceptions even for a short nap.
