Suggestions

Have been on bipap for 7 weeks now. Pressure has been changed 3 times. First time because I was unable to get a seal on my mask. I had to tighten it so much that it felt like someone was pushing there shoe in my face (20/16). Pressure was on lowered on 1/6/15 to 18/14. Then at my request, just to see how I would do, lowered on 1/21 to 16/12.
I have only had one 6 hour stretch of good sleep. At the present pressure my AHI has averaged 1.96 according to sleepyhead.
Sleephead shows my best RX to be 1216-1/5, AHI 0.41.
My questions are: My AHI's were better on a higher pressure but I am much more comfortable at 16/12. Since my AHI's are in the acceptable range is it okay if I stay there?
Earlier I was using the M Quartro Air FF Mask. On 1/21 I started to use a L. Wisp Nasal Mask. This worked okay in the beginning but now I am have to adjust it a lot during the night. Last night I tried to MQA with a padacheek liner. After two hours or so I had to remove it as I felt claustrophobic and used the L Wisp. Any ideas of what I can do about the masks or should I just stick with the nasal and deal with adjusting it. I sure would like to get more than 2 hours of sleep without waking.
Would it be worth posting my sleepyhead data to see if you can see something going on? If so which graphs should I pin for you to view?
Thank for any help you can give me.

Welcome to the forum.

This thread contains examples of the basic graphs that I like to see.

Yes, if a slightly lower pressure still gave me acceptable results and let me sleep better and more comfortably then I would probably use it. Also...a lot of time AHI has come central index in it and more pressure wouldn't fix those anyway.
Example....if your AHI was 1.80 for a night...still quite acceptable but the central index was 0.90...that would make it less than 1.0 for the obstructive stuff that pressure deals with and even more acceptable.

Central Index ?? Could you please explain that?

Clear Airway Index...means central index.
Central apnea events....no air flow but the airway is open...hold your breath for 10 to 15 seconds...no air flow but the airway is open..that's pretty much what a central/clear airway event is.

Respironics calls these open airway cessation of breathing...clear airway events.
ResMed would call these same open airway cessation of breathing....central events.
For practical purposes they are one in the same when talking about these software reports.

We don't treat central apneas with more pressure with the machine you are using. In fact central apneas are sort of ignored when the are in small numbers and if your AHI is less than 2.0...I already know that even if your entire AHI was made up of centrals..you aren't having them in large enough numbers to worry about.
Should people see a large number of centrals then we discuss their options but there is no need to do anything about them when they aren't present in large numbers (like over 5 per hour, for every hour, all night long and every night).

Centrals are common..most people will have a few here and there...not a big deal in that case.

It sounds like the lower pressures are doing a decent job for you...makes me wonder why the original RX was so high unless maybe sleep position was a factor and you don't sleep in that position all that much now. Like if maybe it was related to supine sleeping where it isn't unusual to need more pressure and you don't sleep on your back all that much at home.

I am all for using lower pressures if it gets the job done and a person can sleep better.
AHI of less than 2.0....very much within acceptable limits and sleeping better is preferable to an AHI of less than 1.0 and not sleeping well. Sometimes we make compromises and in your situation...a no brainer compromise. Now if the AHI was over 5.0 all the time and mainly obstructive in nature (OAs and hyponeas) then not a good compromise to make.

My events usually show UA's and Hypopnea.
When I went in for the sleep study I did not lay in my normal sleeping position, on my stomach, because of all the wires. They woke me up at 11:30 and told me I was going on a bipap because I was having over 100 apneas per hour. I did not sleep well the rest of the night. I went in two weeks later for a second study, didn't get set up until 10PM and again was restless but did have some sleep. Woke up at 4AM and was unable to getback to sleep. They also said my O2 levels got as low as 77, therefore I am on 2L with my Bipap. Another oximetry will be done this week without the O2 to see how I am now doing.
Sleepyhead is showing UA's and Hypopneas only. My average AHI is 1.96 but I did have two nights when it was just under 5. Those were very restless sleeps.
