Analysis of Oscar waveforms

My first session looks good - to me.
Looks like the clock is off, I'll look into that.

Did you sleep well? Hypopnea and Unclassified events have you nearly at 5 AHI. This session was at 4.46. You're almost where you're not treated.

I don't remember, why'd they put you on "old square waves" ST? As is, again, it's barely treating you.

If you feel good for it then OK, but if there's symptoms and events it's missing, then there's work to do.

I remember the sleep study said I get central apneas, which the doctor explained were special cases with an unknown cause. I thought the ST was for that. I don't know what the script to DME was. I see a new pulmonologist in July, I'll bring up switching to a different machine. I was thinking an AHI of 5 was near perfect.

No actually the ASV treats Central Apnea. And the ResMed AirCurve 10 ASV is king. The ResMed ST does have a backup rate similar to ASV, but ASV in ASV Auto mode will have EPAP, PS, and IPAP all range within your set parameters to tackle all that's thrown at it.

As I recall, the ST was one old school method to combat CA. The ASV is many times better.

PS do you have your diagnosic and titration results, the detailed reports? If you do, post redacted version as attachments. If you don't, HIPAA law permits you to request and receive these.

OK, I will ask for an ASV and my study results. I remember the Doctor said he pushed the insurance people to get me a bipap device, so maybe an ASV was disallowed by the insurance.
Thanks for the info.

ASV is a BPAP but it also has a backup rate and the algorithm to attack CA. Other machines may work somewhat on Centrals, but the ASV truly is tops.

I found a local ASV model on Craigslist.
First session.

[SarcasticDave94]

OK yeah we can't top the zero AHI. Did it feel comfortable?

[paxnow]

I don't want to jinx it, but yeah very good, very deep sleep. The Auto-EPAP (8.76) was much lower than my titration of 16cm. Very nice! And the Auto-IPAP (max 19.22) matches my prescription of 20cm, and I did not need such a high pressure all night. 

A very well designed device.
Thanks for the advice.

If you want a bit of added comfort, it looks like your Max PS could be dialed back a bit if you want. You likely won't need Max PS of 20. On the other hand, if you're comfortable and keep getting zeros you could let it ride until/unless a comfort issue crops up.
