Resistance Exhaling In CPAP
#1
Ohmy 
I never noticed it before and I've been using it for about a month. The biggest difference is that I switch out the thin line for a climate line hose.

1) If I switch back it still feels the same.
2) changed pillows too and still the same.
3) Adjusted the EPR to 2 (can't really tell the difference between 1 2 or 3)

Any suggestions please?

If your pressure is really fixed at 4 as you indicate in your profile then you won't feel any difference with EPR because 4 is the lowest pressure the machine can go. EPR normally decreases the exhale pressure by 1, 2 or 3 cms. But if you're already running at the lowest pressure then EPR is irrelevant because the machine can't decrease the pressure any further.

Are you sure that your pressure is 4? That's an unusual prescription pressure. And most people feel like they can't breathe on 4, like there's not enough air and it's a suffocating feeling. Can you double check your pressure settings? To access the clinical menu where you'll find the settings:

OK. My guess would be that you notice the difficulty exhaling when your machine is running at the high end of that pressure range, but it would be helpful to get a closer look at what's going on. Are you up for getting SleepyHead software running and looking at the data on your SD card? The graphs showing pressure ups and downs can often help shed light on what's causing what.

Check to see if the exhaust holes in your mask are clear from any obstructions or blockage material that may have been in the new hose and got blown into the mask.

SleepyHead is free software you can use to monitor your CPAP treatment. Click on the SleepyHead link at the top of the forum page. For each night SleepyHead will generate a report which allows you to look at the pressure changes during the night and look for patterns or events that can help you fine-tune your therapy. In your case I'm curious to see how high your pressure actually goes, and for how long. More information on SleepyHead can be found here.

In addition to kaiasgram's suggestion it has been posted here many times and it has been my experience as well that tightening the pressure range will also help you. in order to properly do this you will need to review your data (using resscan and\or sleepyhead free software both available elsewhere in the forum) and see what pressure you are at 95% of the time. Once you do that you can post your graphs here and check with your doctor as well and you will find the best tightened range for optimal therapy and sleep comfort. Good luck with your therapy.

To clarify: The 95% pressure number means that for 95% of the time you were at or below a particular pressure. The or below part often gets overlooked or ignored. So for example if your 95% pressure number is 12.4, then your pressure was at or below 12.4 for 95% of the night -- it may have only been at 12.4 for a few minutes and well below that for the rest of the night. The 95% number may not always be the best reference point -- thus the value (and importance) of studying the graphs before adjusting pressure(s).
