Why standard home test said AHI 8 (twice) but WatchPAT said AHI 46

I'm slipping. Now I'm curious about the ST reasoning myself.

You have which lung condition other than Apnea? My apology, but I missed something important.

Not enough coffee

True.

I did just see earlier on, shortness of breath. Have they begun to diagnose it even start the process? Shortness of breath indicates something other than Apnea.

You might want to read this, which discusses tests for people who experience shortness of breath and fatigue:

Also, you might try to push for an in-lab sleep test, which will be able to do a better job of identifying your events and your sleep stages. (A polysomnography study is what you want.)

Like others, I doubt whether sleep apnea would account for daytime shortness of breath.

Have you these tests: thyroid, testosterone (if you are a man), iron panel, vitamin D, B vitamins, autoimmune disease (especially in the connective-tissue-disease family), Lyme disease. Have you discussed chronic fatigue syndrome with your doctors?

Thank you all for your helpful input. Also I realise this thread includes multiple Daves which made my brain crashed multiple times (just kidding)

Yesterday I got a blood pressure measurement done at a pharmacy - last one I had was so many years ago and it was normal. Turns out I have stage 2 HBP (high blood pressure): 155/102. I immediately ordered a blood pressure monitor on Amazon which I got today - same result (roughly).

So constant fatigue grew from 2016 to 2020, then from 2021-22 frequent SOB (shortness of breath) set in. I suppose developing OSA + HBP explains the SOB. HBP is a typical byproduct of long term untreated OSA.

What's ironic is that (presumably) OSA induced HBP and to fix HBP I need to fix OSA - except I can't, because my main HBP symptom is a face-centered headache/tension that makes wearing a CPAP mask intolerable. I could wear a Bleep Eclipse but it's impossible to get one in the UK.

Constant fatigue since years ago + HBP + WatchPAT AHI 46 result = high probability of OSA isn't it?

Anyway since I can't currently start CPAP therapy I'll acquire an oximeter to see what's going on at night. Thank you guys.

(@PeaceLoveAndPizza: I bought the ST machine secondhand - it wasn't assigned to me by a doctor. I'm in the UK, where you have time to die 5 times before your first appointment with a specialist)

Sorry I had missed your comment. Thank you for the link to the article! I see my neutropsychiatrist tomorrow (the guy who requested the WatchPAT test) and I'll see if he can refer me to a in-lab sleep test and a cardio­pulmonary exercise testing.

(I had countless blood tests so they definitely check for vitamins, iron and thyroid, not sure about testosterone or Lyme disease so I'll check that as well, thank you)
