Has 'mild sleep apnoea' been redefined numerically?
#11
You could set the minimum up 1/2 a point. Not anymore than that. See what happens. You might need to raise the max a little too, but not now. One thing at a time.

Hypopnoeas refer to a narrowing of the air passage, and the machine figures that out through various methods, depending on the manufacturer. While it means that less air is flowing efficiently into your lungs, you are still getting air and unless your sO2sats are dropping precipitously with hypopnoea events I would not sweat that figure so much. If you have a recording pulse-ox, then take a night's readings, hook it into the data for that night and see if you have any major desats during your hypopnoeas. My guess is that you will still be relatively high, over 90% and so there is not much risk of cardiac stress at those levels.

I thought 'mild' OSA was an AHI of 5-15?

Has anyone heard that is has been redefined, or was I told nonsense?

However, the diagnosis is based on your sleep study number(s), not what you are getting with therapy.

Sorry but I don't understand the reasoning - could you explain it further please?

If, for example, I had a another sleep study now but secretly! did it while using my CPAP - on my current treatment results I would have a test result AHI of 5-10, which would then be <diagnosed> as mild sleep apnoea.

I am of course very pleased that my AHI with CPAP is greatly reduced compared to my (real) diagnostic test, but I just think it would be a good idea to try and improve things even further and I do not understand why two different sleep doctors are not at all concerned. If I have to go to bed each night with a pump, hose and mask... I would much prefer that this treatment resulted in <no sleep apnoea> rather than <mild sleep apnoea>.

So surely that suggests that my current CPAP regime is sub-optimal?

Or have I misunderstood missed your point?

There is no reason to think that an AHI of 5 means your CPAP therapy is effective, other than the fact that that's the threshold used to diagnose untreated patients.

Dear Sleepster,

OK, I take your point but, when taken together with my symptoms -
quote <Still tired and not very good sleep quality and increase in insomnia. Oxymetry results are acceptable>
which I mentioned in a previous post in this thread, why therefore are my AHIs on CPAP of 5-10 not relevant?

Please could you explain why a first step to try and improve my continuing symptoms on CPAP treatment would not therefore be to start with trying to find a pressure setting that achieved an AHI of less than 5?

Thanks

I agree that tweaking your pressure to try and get a lower AHI is the thing to do. That's what your doctor is doing. What I and others are saying is don't freak out because your AHI is a bit above 5.

Dear Sleepster,

You have clearly never met me. It would be accurate to say I have never <freaked out> about anything in my life...

It can be rather discouraging to ask something on this forum as a <newbie>.

I think I may not bother again.

Dear Storywizard,

I think the breath should rather be taken by someone before he or she writes misleading words!!

Might make for a more pleasant world...
