[CPAP] OSCAR Interpretation - UARS?

[Jay51]

Charts look ok IMO.  Tidal volume is up and that is great.  0.00 95th percentile flow limitations is excellent.  The machine raises pressure at times during your sleep, but your charts look pretty clean of events.  Hopefully this current machine you have will work out for you.  

Of the different modes you have trialed, which one caused you to feel the best in the morning?  Straight Cpap or using EPR?

I can't seem to find consistent relief despite a wide range of both cpap and apap.

I don't think the number of events are accurate as I see large portions of shoddy breaths (RERAs?) which I'd be happy to post
Zoomed in pictures about.

So far APAP 11-14 has produced 3 ok nights of sleep and CPAP 15 has produced one decent night. Each setting seems to stop working after a few days.

Apart from some apnea clustering on the 24th around 1.30 am, indicating some positional apnea, I can't see much else that is wrong. 

But there must be considerable arousals not shown that are contributing to poor sleep quality.

Otherwise I could not see anything obvious that is causing poor sleep quality. 

Perhaps it is time to look elsewhere for some undisclosed micro awakenings (arousals).

You mentioned headaches. That made me think of oxygen desaturation events, and the need for more data. 

Adding an OSCAR supported oxymeter would give 2 extra graphs, Sp02 and Pulse Rate, and could be compared to the flow rate, and respiration which may reveal some clues behind poor sleep quality. 

Importantly, we also obtain the ODI, (Oxygen Desaturation Index) , expressed in drops in oxygen levels 3-4% per hour or more. Evidence of headaches? 

Such data could give a doctor a line of further investigation perhaps outside sleep apnea. 

The above are just some ideas to work on....
