1 in 10 of you were misdiagnosed in your sleep study

It is well known that sleep recorded in the
laboratory is confounded by the “first night effect”
which is characterized by lower sleep efficiency, increased
wakefulness, reduction in rapid eye movement
sleep (REM), and longer latencies to sleep. Evidence
suggests this phenomenon is not seen in the home.

Glad I was one of the 9!

My first two Sleep Lab tests that were done in Ohio pointed to Sleep Apnea but the doctor wanted and did treat me for Narcolepsy.

My intended read my chart and all the findings and he asked why I wasn't on a CPAP machine.

My new doctor read this same report and he shook his head. This is when my sleep study was done and they discovered that I really had sleep apnea. So now I am on the S7 Lightweight.

My intended said that my former doctors were all screwed up.

My sleep doc said not to pay too much attention to the "sleep architecture" data in my sleep study ( how much spent time in various stages, sleep latentcy, etc) because a night of sleeping in a lab is not your "normal" night's sleep. Still, he thought the OSA-related data was still meaningful enough to make a diagnosis.

I found it reassuring that he took the weirdness of sleeping in a lab into account when intepreting results.

I suspect that mine was not quite accurate because I didn't sleep long enough. My oxygen saturation never went below 85%, but I know that I usually only start dreaming later in the night. I've read that apneas are more common at this time. I know that if I wake up after having dreamed for a while I'm groggier than if I wake up earlier. My guess is that my oxygen saturation tends to get much lower later in the night and the test didn't pick this up.
