That's interesting.
I've found over the last three months that the time in Apnea is a far better indicator of tiredness the following day than just the AHI number itself.
I've had nights at 5 AHI, but felt fine, and I've had nights at 2AHI where I felt exhausted. Looking at the event list it seems to correlate more to the duration of the events and not the amount.
The night before last my CAI was 5, but I felt totally exhausted.
When I looked the CA event list (see below) there were 45 events in total, but many of them were longer than 30s as you can see below.

Is there anyway to get OSCAR to multiply the AHI by the 'total event duration/sleep time' to give a 'time in Apnea' figure? I'd love to test the theory.

Doesn't your Oscar show the Total time in apnea?

It does as a total, but not a per hour value like AHI is. It's not too hard to do that manually, but it would be nice to have there in OSCAR.

The per hour AHI chart is the absolutely most useless chart in the whole thing.

Exactly, which is why I think a total time in apnea per hour, inclusive of flow limit and RERA, would be a far better indicator of treatment efficacy.
All of these are measure able within OSCAR and the calculation is simple. Anyway, just a thought.

I’m glad just to have found such a knowledgeable community that are willing to help.
My doctor just said that I have OSA, and need to try CPAP. He handed me a Dreamstation set for 4-20 with AFlex1 for a month with no support or follow up, and then told me I had to buy one.

So you're thinking a graph that increases with any sort of breathing problem, averaged over some number of minutes, to show where there's more issues, then compare that to the pressures, giving an idea what you might need to do with pressure.

That'd work easier on Resmed compared to Philips, since Resmed provides more detailed snoring and flow limitation data, Resmed says "this is happening and it's that bad" whereas Philips just says "something happened".

I was actually thinking that OSCAR could do the analysis based on the flow rate waveform, giving a standardised assessment rather than relying on the manufacturer's event interpretation.

Practically same result last night.
Some more CAs associated with awakenings.

I'm in Adelaide and thank god last night we got heavy rain and cold weather (for Australia at least). Bit of a noisy night, but we're bloody delighted with the rains. It's been tough lately, and I'll take extra CAs over bushfires any day!

Oscar reports the data. it doesn't analyze or interpret or generate data.

Hence why I said that it "could" do the analysis too. If it did then it would remove a lot of brand based subjectivity from the game.
I realise that the developers are working for free so it's obviously not a simple matter.

There was a definite decision *not* to do analysis of the data, we don't want to be seen as "playing doctor".

Mark did that crap in one version of SH and freaked out a lot of people with his alarmist "warnings" on the opening page. It caused problems on all the forums that promoted SH use.
