Simplex mask not giving good AHI numbers

[blogel]

Hello, I am new to forum but use CPAP for 3 yrs. Like my new Simplex mask but normal AHI is <2 and with Simplex it is >5 typically. My pressure is 11. Do I need to change some settings such as pressure on my Respironics? Mask fit is comfortable with not major leaks. New tubing also. Any suggestions please? Thanks and I appreciate your time.

blogel,
Welcom to the forum!
What were you using before the Simplus?
Some report that they need a little higher pressure with a full face mask.

Your profile doesn't say what System One you are using. Is is a Cpap or APAP?

I also notice that your list ResScan as the software you are using. ResScan is only for ResMed cpap's.

You should be using either Encore Basic or Sleepyhead software.

You can access sleepyhead software download by clicking Sleepyhead at top of this page.

Encore software:

Thanks OpalRose. I have gone up to 14 cm of pressure at the advice of my respiratory therapist but only once, and had no improvement. Maybe I will try this approach again and be more patient. As to software, I use what the machine came with and I just took a guess. I really don't want to fool with the software. My best device is the large nasal cushion but sometimes I get a little claustrophobic with it. It gets my AHI steady from 0 to 2 however. The nasal pillows don't work as well but are very comfortable most of the time.

biogel,
I understand if you don't want to mess with software, but it's pretty hard to advise without seeing some data.

An AHI under 5 is considered treated, but the big question is: How do you feel?

You are getting an AHI over 5 using the simplex, and that could be due to mask leaks or mouth breathing. Have you tried mask liners? A chin strap may also help.

Hi blogel and welcome.

I recently went from a Resmed Quattro Air to the Simplus and it is a big improvement regarding leaks and comfort. However, my AHI went up from consistently below 1 to consistently over 2. No idea why, but it does seem that different masks can give different results. I bumped up my epap a couple of points and that seems to have stabilised things.

On Resmed machines (and I assume it's the same on Respironics) you need to change the mask type if you change between pillows or nasal mask and full face. Also on Respironics machines there's a setting for the intentional leak rate of different masks. It may be you need to make these adjustments. I'm not sure of the details but perhaps somebody with a Respionics can chip in.
