Adjusting psi on a resmed S9 auto set

I got a Resmed S9 auto set a couple weeks ago(my old machine lasted 10 years & was starting to make noises) they set my pressures for me but I'd like to lower my min. psi. Can anyone help me with how to do this or do I have to take it back to my DME supplier?

- Press the setup button and the push dial simultaneously for 3 seconds. This will open the clinical menu.
- Go to "settings" and scroll to the pressure you want to adjust.
- Press the push dial, and the background colour will turn orange.
- Now rotate the push dial to select the pressure you want, press the push dial again to save it
- Scroll down to "home" and click on that.
- Done.

Can I ask why you want to adjust the minimum pressure? If you're having trouble falling asleep because the pressure is too high, you might be better using the ramp, or increasing the ramp time from its current setting.

Thanks. I want to change it because she set it at 7 & I think it's blowing a tad too much air at times in the middle of the night & giving me dry mouth. My mouth is taped so I know it's not mouth breathing & my old one was set at a min. Psi of 5.

This is the way that I have adjusted the pressures on my S9 Autoset for APAP mode:

If my prescribed therapeutic pressure on CPAP was 14.5 cm then I would start the APAP pressures on 14.5cm max and 11.0 cm min. Next, I would spend a night with this setting and get a pressure graph on ResScan (b/c I have a Resmed machine). The graph would show the pressure curve plus the two limit lines. Next, I would start adjusting the set-up on the APAP so that the pressure curve only "kisses" those limit lines. The reasons: I don’t want the machine to suddenly boost the pressure needlessly and give me emergent central apneas (Complex Sleep Apnea) and also cause more leaks b/c of the higher pressure. As to the low pressure limit I set it so to have the machine respond more quickly to events.

If you are feeling the pressure is higher later and not right away, that is not the minimum pressure, but what it is going up to as it responds to prevent apnea events.

If it is going too high, you may need to check your maximum setting. But first, it would be best to look at your graphs for the last few nights and see what it is doing. It may need to go that high, or you may need to make some changes in your sleep positions. Or your mask may be having some leak issues.

By lowering the minimum, it will take longer for the machine to get to the level it needs to prevent events. And it will still go up higher in the middle of the night.

Can you post some graphs of a typical night?

We mainly need to see pressure, events, and leak.

I don't have any way of viewing graphs.

If you have the S9 AutoSet you can use free and easy to use software to see the data that the machine gathers.
SleepyHead will work with the AutoSet. I have links in my signature to information on how to get, install and use the software.
How to post images of those reports discussed in this thread along with some examples.

Just looking at the S9 screens and creating a log should provide plenty of information. Same when using ResScan Stats reports. The more you post graphs the more the interpretations differences by laymen instead of your Doc.

Examples:

One night ResScan Stats:

On this night the Leak of 25 L/Min was excessive but the Events were shown OK. Otherwise they would show as Unknown and be colored yellow. See the events graph below for Dec. 14.



60 days ResScan Stats:




One year ResScan Stats (the values are sort of medians and averages for the single night values):




My Pressure and events graph (how cleaner it is compared to SH!)

Notice, these are the results of the procedure that I mentioned in my above post for setting the minimum and maximum Pressures on my APAP. I repeat it here:

The pressure curve still touches the lower limit near the middle of the sleep time. So I plan to lower the min pressure by about 0.5 cm.



Another Pressure graph from another date:



A graph of Leak like the following could lead to a lot of discussions. But if you look at the ResScan Stats reports for long periods you'll see that the S9 decided that
overall, the Leak at 95% percentile, is OK:

I can't get to the area to change my psi it won't let me help I can't breathe

I have a Resmed S9 autoset with a pressure set at 4 and only get partial relief of apnea symptoms. A sleep lab test was done in 2009. A very recent sleep lab test was done with titrated pressure increases during the night, and despite short total sleep time, I woke much clearer, and hopeful. A prescribed change in pressure awaits sleep lab test results in the doctor's hands. I'd like to adjust my Resmed S9 autoset myself while waiting for a prescribed change but the he steps outlined in a CPAP talk post, e.g., press both buttons for 3 secs., etc. did not work. I could not get to 'settings'. Any help would be appreciated.

welcome to the zoo! you might garner more attention to your post if you were to post it as a new topic. some of the seasoned veterans here will overlook a thread like this because the thread itself is too old.

now, having said THAT, someone will come in and start offering advice!


good luck!

That's because that's NOT what the instructions are.

Do what zonker said and start you own thread.

Then go to apneaboard, click the link at the top of the page, and request a copy of the clinical manual by email..
