cpap not recording the right therapy hours.

[montyb006]

I just recently changed work shifts,working third shift ,so I sleep in the morning. I sleep over 4hrs and the cpap always reads under 1.0. My last reading was 0.7 for1-day. Mask is not leaking, and I have the correct air flow..

Exactly which brand and model machine are you using?
If ResMed...are you sleeping past Noon per the machine's clock? If so, a new sleep session is started at 12 Noon so hours of use will be split at Noon.

I am using Resmed and set the time of the machine 6 hours backward to avoid my sleep record split into two days.
