Just the other night, however, I became semi-awake having the feeling that I had something attached to my face that was blowing air at me. For some reason, I thought that the blower was integrally attached to my face. For some reason, it seemed important to me to get the blower turned off. I searched all over my mask and could not find any switch with which to turn it off. I did find a "thick cable" attached to the mask and started following it back to where it was plugged in to the wall. (You can probably see where this is going.) I was having to go too far along the "cable" and finally decided to just jerk it out of the wall socket using the "cable".
I finally became more awake and realized that I had pulled the whole machine off and onto the floor. I got the machine turned off and removed my mask and picked up my poor machine. Luckily my PAP sits on a surface that is only 4 inches above a carpeted floor. Also as luck would have it, this happened after 4 or 5 hours of sleep so the humidifier was nowhere close to being full and the machine just tipped. It did not even roll to vertical. I put everything back in it's proper place and masked up and turned it on. Everything has been working fine ever since.
I guess I do some weird things when I am half asleep but I never expected anything this weird. Thank goodness I did not fry my VPAP.
Please do not try this at home. It requires a certified "Lucky Idiot" to do this without severely damaging your CPAP.
