Minimum settings on Resmed S9
#1
Hello - I have used an S8 for six years, and recently purchased an S9 auto. I have never had a sleep consultant, but after my sleep study the clinician there told me I probably needed a setting of 13. I varied between 12 and 14, and recently was at 14. I am absolutely on my own.

The S9 has so far exceeded my expectations, and my question is about minimum pressure settings. I used the machine the first night with the minimum at 4. I thought the way it worked was that the machine supplied pressure as needed, but mid night I found I was gasping for air. Then I adjusted the minimum to my old pressure (14) and it was way too much. So I upped the minimum to 5 and awoke myself snoring, which I thought the machine wouldn't let happen.

So the final min adjustment right now is 8, and seems to be working, but I am asking if I have to set that or the machine will judge what I need? Bit convoluted, I'm afraid, but I hope you get the point.

Thanks
Franko

An APAP can adjust the pressure according to your needs, but it adjusts the pressure in response to events. In other words, you want the minimum starting pressure to be somewhere close to the needed pressure. Otherwise too many events will have to happen before the machine raises the pressure up enough for the pressure level to be effective.

In addition, once you are used to breathing with a fair amount of pressure, really minimal pressures (like 4 or 5 cm) may feel like there's not enough air coming in through the mask.

The interesting question is why does the S9's 14cm seem "way too much" when the S8's 14cm was not causing you too many problems. One question that immediately comes to mind: Did you have EPR turn on on the S8? (If so, what was it set at?) Did you forget to turn on EPR on the S9? A second question that comes to mind: Are you using the same humidity settings? A third question: Is it possible that the smaller hose on the S9 is just making the same amount of air feel more forceful?

Finally you ask:

The answer is A bit of both. As you've found out the hard way, it can be uncomfortable to sleep with the machine set wide open or with a very low minimum pressure setting. Manually bumping up the min pressure (as you have done) can make things a lot more comfortable and make the PAP therapy more effective. But at the same time, the data the machine gathers each night can also be examined and analyzed---even by you---and that data can let you see what the machine is doing in terms of adjusting the pressure every night. The trends in how it adjusts the pressure can be quite useful in figuring out what a good minimum pressure setting is for maximizing the effectiveness of your therapy.

just to make sure I understand some of what you are saying, what is your pressure range settings on your new S9 auto?

Well, when I got my S8, I was a walking Zombie - I would sleep 12 hours and wake up exhausted. I was incapable of making decisions and finally my daughter made the appointment, and I just showed up. All that to say, I didn't even know the S8 had EPR - that certainly would have helpedSmile

So I am only into my first few nights, and I love this machine, and because I have been reading all this wonderful information, I feel like I have a much better handle on the equipment. When I got the S8 all I wanted to do was sleep.

I will use the software and the data to fine tune things, but I am once again sleeping the night through, and everything else is just going to help.

Cheers, and thank you so much.
