AHI

Post by ymood » Sun Jul 08, 2012 8:46 am

Dear all,
My AHI 31 for sleep study with large amount of central apnea. I am new to APAP machines. For the last few days with the APAP my AHI is about 11. The APAP pressure is set to Min=4 and Max=20. what pressure to adjust the machiine so that I get better therapy and lower My AHI.

The first thing to do is to keep an eye on your Leak rate. Until your mask and mouth leaks are under control you really can't trust your AHI data too much.

Once your Leak rate is under control for a full week you can set your pressure at 1-2 cms under the 95%-90% pressure reported by your APAP and 2-3 cms above your reported 95%-90% pressures for a week.

As long as your Leaks are under control you can adjust your pressure again based on the new reported 95%-90% pressure.

If/when you elect to increase the minimum pressure may I suggest that you go up slowly and watch your reports.
If your 90% pressure is 10 cm...and you jump from 4 cm minimum to 8 or 9...you may find that increase a bit disturbing to your sleep quality. Going up in small stages is an easier adjustment and you might get lucky and find you do well with less than you originally thought.

There is no way we can offer any ideas without seeing the software reports.

Also...check out this link to thread for an example of the report that we like to see. Daily detailed report...the other graphs that are offered don't help much...need to see the individual daily detailed...not necessarily all of them but just a couple that shows your typical night.
