Hi dh37,
When you say you don't trust the diagnosis do you mean you don't think you have OSA? Are you not interested in being treated?
Simply that I don't trust doctors. All I have is the word of a non-technical office person that the MD said I have severe OSA. It's certainly possible. I'm missing a lot of risk factors (no BP problems, not at all overweight, very few headaches), but I do snore really loudly (at least on my back), and I've "simulated" what my airway does by relaxing as if I were sleeping. (While that doesn't lead to obstruction, I can feel my airway narrow, and I while I look somewhat athletic/muscular, my muscle tone in general is pretty poor, so I wouldn't be surprised if my airway were relatively "floppy".) And I never feel like sleep is fully restorative, and it's getting worse with age (I'm early 50s). (Not to mention occasionally I have bad night sweats, though that might be due to taking an SSRI.)
In Alberta Canada(where I live) it is very common to be diagnosed with a home sleep test. There are studies that compare the HST to an in lab study. The HST is quite accurate.
While I'd rather have an in-lab full polysomnography study, I'd definitely trust a home HST. (At least, I believe/agree that the false positive rate is probably pretty small, and mine was positive.) I don't trust the doctor, not without me asking "what did you see in the data?" Of course, it's harder to believe the result isn't valid if it's "severe," since there's less room for monkeying around than for mild/moderate.
I have used the Resmed Apnealink Air on 3 separate occasions. The last 2 times I got it for the weekend so I could 'suck' the data from it. The application that can read the data is available online. The problem is that is if you use the data it is removed from the tester. There is no data for the doctor to analyze. If you get it for a couple of nights you can take one nights data and leave the second night to be analyzed.
I feel the Apnealink Air gave a pretty accurate evaluation of my OSA, even though I did not think I had OSA when I took the first test about 16 months ago.
OK, thanks for the info.
