new machine, worse results ??? - Jst617 - 07-18-2022
I started on a cpap machine in late March, an Ibreeze, and had immediate success. My AHI was almost never above 1.0 and I felt great, no more daytime naps, and able to stay up late. After two months, my mahcine provider closed their local office, and the office in Erie PA said I had to get a new machine, they didnt support the Ibreeze. I got a resmed airsense 11, and now I am lucky if my if my AHI gets below 3, its normally 4-5. I feel like I did before I started, not rested, back to napping in daytime, etc. They have checked the pressure, and adjusted settings, but nothing seems to work, On the Ibreeze, I could see and adjust settings, but the resmed only allows me to adjust ramp and humidity. The therapist first adjusted EPR, then turned it off completely, with no change in results. Anyone else experience this? Any thing I could check? I hate typing this at 10:00 am, and feeeling like I need a nap already....

Hi Jst617! -
Four things before going any further,
- If you don't have one, get an SD card. If it is used, format it to a FAT32 before use.
- Download OSCAR for your type of computer's OS. Here is the link: https://www.sleepfiles.com/OSCAR/
- Request a Clinician's Manual for the AS11. This will tell you how to enter the AS11's configuration menu. Here is the link that will tell you how to request one: Clinician Setup Manuals (Scroll down to Section 3 for the request instructions.)
- Read the links in my signature to help in understanding OSCAR and how to post images here.

is your machine auto cpap or just a cpap with single pressure?
if your machine is a single preassure machine then thats must be your problem as ibreeze is an auto cpap it increases preassure automatically when it detects apnea events while single preassure cpap dose not increase pressure when it detect apnea events

thanks for the tip...seems my new machine is Autosense, but set for fixed cpap mode. If my prescribed pressure is 8, what would be good settings to start with for the min/max on autosense?
RE: new machine, worse results ??? - Psychotech - 07-18-2022
Min-6-8, max-12-16, epr-1-2, keep on playing with setting according to your comfort between the given parameters
RE: new machine, worse results ??? - Jst617 - 07-18-2022
EPR levels ?
is that a level, or a pressure, so 1, 2, 3 is low , med, high, or 1, 2, 3 psi ?

Here is the link to our Wiki about EPR: http://www.apneaboard.com/wiki/index.php/Expiratory_Pressure_Relief_(EPR). The pressure of a CPAP for most users is displayed in centimeters displacement of H2O. We usually write it as just 10 cm or 10 cmH2O. The EPR value reduces your exhale pressure by its displayed value in cmH2O. However, the lowest pressure your CPAP can deliver is 4 cm. So no matter what your EPR setting is, the pressure drop will not go below 4 cm.

The AirSense 11 line has 3 different models:
- AutoSet (auto adjustable)
- CPAP (fixed pressure)
- Elite (fixed pressure)
It should say something like "AirSense 11 AutoSet". It would help to know exactly which machine you have.
Once you have confirmed the model you can update your profile. Click on UserCP at the top of the page to edit your profile.

OSCAR will tell you which model you have, as well as the mode you are using...

UPDATE, after two nights of adjusting settings, I think maybe I got it, first night was 6-12 for the pressure, EPR 1, a little better, but still not so good, AHI events 6.5.....last night was 8-14, EPR 1, AHI 2.0, feeling great so far, no need for the morning nap, I'll try those settings again tonight, hopefully same results tomorrow.
