Pressure(s) suggestions please..
#11
Thanks Mongo... and I do remember that old expression... lol.

I'm going to see how it goes tonight and go from there. I know myself and one or two nights is all it's going to take to know if what I changed will work for me. Chin strap - I'm going to try to avoid that. I tried and couldn't deal with it.

Keeping a log is a great idea. Thanks very much for coming to my rescue!

Hi PositiveMe123,

Near the top right of Apnea Board webpages is a "My Profile" link which makes it easy for us to edit our profile.

I suggest you edit your Profile under CPAP Pressure to say something along the lines of 6/11 PS=3. This would be enough info for others to understand your EPAPmin is 6, IPAPmax is 11, and IPAP is always 3 higher than EPAP, and that your machine is in VAuto therapy mode.

Whenever your machine raises EPAP this means the machine is seeing signs of obstruction or partial obstruction in your breathing: things like Flow Limitation, or snoring, or hypopnea, or obstructive apnea. When these signs of obstruction occur your "Auto" machine will raise the pressure; your machine may raise EPAP and IPAP together, but not higher than EPAP of 8 and IPAP of 11.

Flow Limitation means that during inhalation your airway is narrowing and is restricting your ability to inhale freely, which increases the amount of effort needed to breathe in and may lead to Respiratory Effort Related Arousal (RERA).

An apnea is scored by the machine when the amount of airflow into and out of our lungs reduces by 90% or more, for at least 10 seconds. If the reduction is between 90% and 50% for at least 10 seconds, the machine scores an hypopnea.

If the reduction is less than 50% but there are signs of increased Flow Limitation for at least 10 seconds, followed by tell-tale signs of an arousal (sudden large "recovery" breaths) this event was probably a RERA. The machine will not count this as an hypopnea (because reduction in airflow was too small), so the machine will not include this event when calculating the AHI.

Most Philips Respironics System One or newer models report RERA events.

Most ResMed models do not report RERA events, but APAP and other Auto models (like yours) do respond to signs of obstruction like Flow Limitation by raising the pressure, to open up the airway more.

Take care,
--- Vaughn

Hi vsheline... Thanks very much for your suggestion that I edit my profile. Since I just changed the pressure(s) today, I'll wait a few more days before I edit so that I know for sure the pressures are working for me.

Your info cleared up many things. I have a good sleep doctor but I'm getting very tired of seeing her. She always looked at the data on my SD card, said it was very good and sent me on my way. Now, after five years, I've decided to learn all about my machine so that I can handle this myself. Up until now it was just easier to hear my AHI was under 2, and not enough leaks to be concerned about. It's a bit of a learning curve for me. Oh-jeez Thanks again!

I know what you mean. I'm a senior citizen; and I just bought my first smartphone. It will take me a while to semi-master it.

Hi PositiveMe123,
I know there is a learning curve, but it sounds like you are doing fine and you'll get there.
It's great to hear that you are taking your sleep apnea into your hands.
Good luck to you with this, and keep up the good work.

Well, all you really have to do is find a grandchild; any grandchild will do. They will spend 3 minutes showing you how to use it and then think you mastered it! I didn't want to break my grandson's heart so I just said thank you dear, and now I can do everything you do. Too-funny

After fiddling with a few different pressures yesterday, it seemed more comfortable to stay at min 6 and max 10, changing the ps from 2 to 3.

I remember that I woke up once to change positions and fell right back to sleep. This morning when I looked at the display on the machine, there was a big green smiley face and my AHI was 2.1. It seems that just changing the ps from 2 to 3 made such a nice difference; I didn't feel as though I needed more air and my mouth went from extremely dry to slightly dry. I slept 8.2 hours and feel better today than I have in ages!

Thanks to everyone who made suggestions and for your encouragement. Yes, I will edit my profile. Smile Smile Smile

Hi PositiveMe,
You really need to get SleepyHead software going so you can better monitor your situation better.
It's easier than learning to use a smartphone!

What SleepyHead will do is tell you "The Rest of the Story" (like Paul Harvey)

You doctor cannot oversee your therapy as well as YOU can.

Hi Shatzi... I'll think about your signature when I'm attempting to get Sleepyhead. Especially because I am so NOT tech savvy! Bigwink Smile
