How to work out the correct pressure required ?
Hello,
I am trying to find out what pressure will suit best to an individual. He was using an Devilbiss Intellipap machine and had set the minimum pressure to 5 (who knows why). Average AHI was around 8 ish (given the machine gives a code which needs to be looked up on Intellipaps website). So, we set his pressure to a min of 7 and the AHI has been averaging around 5.5 with a much better quality of sleep over the past few weeks. This weekend I lent my machine to him and with a min pressure of 7 we got an AHI of 4.29 - assuming I was on the right track - the next night we bumped it up to 8. The AHI dropped to 4.02. But other events popped up. I have attached both night's charts. I'd be grateful if you could please give your opinion on what would be the right way to self titrate and find out what works ? Sadly, I can only lend my machine over the weekend so we have only two days a week to give it a go.

As long as the pressure is not bothering the person, I would suggest raising the pressure to 9. The AHI is dominated by hypopneas, indicating that the pressure is too low.

Your second link didn't work out so good, but you're a member and could just embed the image. The first one is below, and if second one resembles this, the events are still all hypopnea with a couple OA and some snores. Typical for Dreamstation, this is obstructive. Either keep increasing pressure, or get a Resmed Airsense 10 Autoset (See Amazon at $440). The Philips is pretty reluctant to increase pressure but the Resmed gets it before the apnea happen. I would take this to 9.0-13 and see i it get a bit better.

You can find information about how to set a machine here:
http://www.apneaboard.com/adjust-cpap-pr...tup-manual
That is also where you can get the clinician manual for his machine since you will need to know how to get into that menu to change the pressure.
And here is advice on how to change the pressure your/his self:

Mostly you will need patience and, if the machine is data capable, you will need SleepyHead.

A comment. We will be able to dial your friend in on Your machine. You are using EPR of 2 on your machine. Though EPR is considered a comfort setting it does have an impact on therapy. You NEED to make sure the the DV machine is set up in a similar manner EZ Flex of 2? not sure of the DV term.
The best results will be obtained by looking at the Intelepap charts.
