From: corntoasty1 on 4 Jun 2008 13:50 I have an appointment with my DME next week to discuss this problem, but in the meantime I'm hoping some of you will provide some input. I've been concerned about the high AHI numbers I'm getting...they range from Day: 22 all the way to 43, weekly and monthly means reflect the same high numbers. So this afternoon I connected the machine as I do every night and just stayed awake for 25 minutes breathing normally. When I started the Daily data was 0, after 25 minutes it showed a AHI of 36.2. Does anyone have any idea what's going on here? I've had this machine for 5 weeks and I'm assuming it was new when I got it and in good working order.

The test while you are awake won't really show anything useful because it doesn't represent breathing pattern whle you sleep.

If my nose gets blocked, I'll sometimes fall asleep breathing in through my nose and machine, whilst breathing out through my mouth. Once thr ub eventually clears the nose, then I auto return to breathing out throught my nose. I hot the Resmed machine gives losts of red spokes during the nose in-mouth out period.

Something's wrong if it's showing an AHI of 36 when the guy is awake, though. My guess, as your's Andy, was mask leaks. Failing that, and assuming the OP was sitting/lying down *very quietly* when he made the test, I can think of two other explanations. First, the OP fell asleep but didn't notice. Second, the machine is faulty. If, on the other hand, the OP did the test whilst he did the ironing, washed up the dishes, or read the newspaper that could lead to lots of changes in breathing that the machine might mis-recognise as hypopneas. I'm going to try the experiment and report back. Maybe others could too?

But why should it make a difference if you are a mouth breather? |
