Resmed Autoset 10 and Sleepyhead
#1
Hi guys,

Brief history, first CPAP machine was a Resmed S8 from 2008. It served me well but it was time for an upgrade, so managed to get a Resmed Airsense 10 Autoset. Sleep doc said I had good results at 10 cmH2O from my sleep study, so he prescribed an APAP setting of 7-15 cmH2O.

Been really happy with the device so far, especially with the Airfit P10 nasal pillows. After 5 days of use, I gave SleepyHead a try and was pretty amazed by what data I could see. I noticed that while my median pressure was 10.84 cmH2O, my 95% pressure was 14.75 cmH2O. Does this mean I should be safe to increase the max range for APAP? If so, what setting would you recommend?

G'day wongnog, welcome to Apnea Board.

The 95 percentile figure means that your pressure was at or below that pressure for 95% of the time. Or in other words, it was above that pressure for 5% of the time. Without seeing your charts it's hard to be sure, but my guess is that you'll have a few flat spots in your pressure graph where the machine has reached the maximum of 15 and is trying to go above. There's no harm in setting a higher maximum - the machine will only go higher if it needs to to treat your apnea. However I suspect you won't notice much of a difference as the time at maximum is relatively small. Like everything else in this game, only adjust one parameter at a time, in small steps and wait a week or so between changes to see what the trend is (you can't just rely on a single night's figures).

yep. I would wait until you have about 2 weeks under the first settings. Then take the result and use that to change the range. Then -

If you have a median of 10.8 cm throughout that week, I would gradually change the min pressure to 10. If sleepyhead shows that you are up against the 15 (like 14.5 and above) a lot, then adjust the max up.

A good rule of thumb:
adjusting max - adjust by 2 cm at a time, no need to wait long for additional raise.
adjusting min - adjust no more than 1 cm at a time, and wait at least 4 days before next raise.

Since you probably will be at 10 min 17 max, you'll do therapy at current settings until March 9.
Mar 9 change from 7-15 to 8-17
Mar 13 change from 8-17 to 9-17
Mar 17 change from 9-17 to 10-17, or 10-19.
Wait a couple weeks after that, and check your progress.

Thanks for the tips guys! So far I'm loving the MyAir site as it gives me quick visibility of my CPAP compliance. I'm totally amazed with the SleepyHead software. It's quite advanced and free to boot! I'll keep my settings where they are for now as I'll be going away on vacation soon so won't have time to monitor my progress.
