First Night with SH Data Please Help.

I have been jumping the gun a bit. I will give 8cm a try starting Sunday night. I need a weekend break from pap too much stress and I get slightly better sleep with nothing. Does the Resmed S9 VPAP Adapt have an autoasv?  What do you guys think of drugs like acetazolamide to treat CSA?

And I have nasal valve surgery this Thursday. Maybe magically this will heal everything lol

The Resmed S9 Vpap Adapt is an ASV Machine it comes in two variants one model number 36007 which is the oldest model that has a fixed epap called ASV mode and the newer model 36037 which in addition to the ASV mode has an auto ASV mode with variable Epap based on snores and flow limitations. The later model algorithm is identical to the newer Resmed aircurve 10 ASV

Hi, I have taken your advice and tried cpap 8cm straight pressure. Here are the results.. Do you think 7cm may lower the CA's even more?

[Sleeprider]

You can ratchet the pressure down a bit slower than that by trying 7.4 or 7.6. I think you're definitely in the ball-park here getting that CA under control. Was this more restful?

Yes, I just wish I slept longer.

If your clock is accurate on your graphs, then longer sleep times might mean seeing what you can do to transition to an earlier bed time.  Had you started at 22:00 or 23:00 this could have been 8 to 9 hours.

I have an s9 vpap adapt 36007 coming in this week in case I am unable to get my AH under 1.5. I got a very good deal on it. But tonight I try 7.4cm

The S9 Adapt is a whole different approach. You seem to tolerate fairly low pressure, which will work in your favor using ASV. It would actually be a good idea to identify where your OA threshold is, and use that as the minimum EPAP pressure. The pressure support will then be used to stabilize the breathing rate and resolve CA. In your last graph, there is some periodic looking breathing at 06:20 to 06:40 and that is something the ASV deals with. It will be an interesting trial, but it also takes some time to get used to the pressure support intervention on ASV.

Sounds Like a good approach.  This maybe a dumb question but what would periodic breathing be under?..  I still do not know much about reading data.

Periodic breathing is just a repeated or "periodic" increase and decrease in the respiratory flow rate and volume. In an acute case, it may have an apnea at the minimum. There are a lot of graph examples of it if you want I can post some. Yours is relatively mild and not even flagged. With ASV, the machine will apply more pressure support when your respiration volume drops, and less when it is normal in an effort to keep every breath about the same size. The Resmed ASVs including the Adapt actually measure your baseline respiration rate and volume and maintain that.
