Think I finally have things figured out
#1
Diagnosed with severe sleep apnea in April 2015 and placed immediately on Bi-pap. I struggled with things initially and for the first 38 days with my pressure set at EPAP 5 and IPAP 9 my AHI for those 38 days was 19.9. My doctor put me on auto pressure and my AHI dropped to 11.82 over the next 16 days. Since then I have been back and forth between a set pressure and auto pressure with not much relief. I did have a stretch where my AHI dipped below 5, but only for a short while and then it spiked again at 12.5. I really didn't think I would get down and stay below 5 (which is considered treated) and I would be dealing with it forever.

I finally decided to change my pressure back to a set EPAP 4 and IPAP 7 and reduced my AHI to 6.6. I still wasn't there though and I was having a large amount of mask leaks despite tightening the mask to the point where it was putting a lot of pressure and pain on my face at night. So I decided to lower the pressure to as low as it would go. I put my EPAP and 3 and IPAP at 6, loosened my mask and hoped for the best. My first night my AHI was 7.1, but the next night it was 2.9 and the next night it was 1.5 and the next it was 3.0. In the last 31 days I have had only one night (June 1st) where my AHI was above 5 and I have had 7 nights below 2. Overall for the last 31 days my AHI is 2.7. Not only that, but the amount of mask leaks I have had has been almost non existent (0.74% of time above Leak Rate threshold) and most of that has been when I've gotten up in the middle of the night to use the restroom.

I think I finally have it figured out and have been sleeping so much better and even longer than in the past. I still get tired during the day though and find myself dozing off in my recliner, but I truly do feel better when I wake up in the morning.

Hi wxmcpo!

Welcome

Most masks use a silicone seal that works in conjunction with air pressure to complete the seal. Over tightening defeats the design and is very uncomfortable, You might try slightly pulling the mask away from your face immediately after turning the CPAP on. This will allow the air to expand the seal and might allow you to wear it a little more loose. Since there are some many face structures, you might try other masks models. Each one will fit a little differently.

Good luck.

Master Chief: I just don't see 6/3 being an adequate pressure for sleep apnea.
Something is just not right.

Hello, wxmcpo. It is certainly unusual for someone to get good AHI results with such low pressures. I see in your profile that you use SleepyHead. I'd be interested to see your events, pressure, flow rate, & leaks graphs for any nights if you'd care to post them.

About what you said about seeing machine leaks when you get up to go to the bathroom - do you turn off your machine before you take the mask off? If you turn it off first, I think that will help you avoid any leaks being recorded.

Best regards.

You know I thought the same thing. I was surprised that it appeared to actually be working. Here is a screenshot of the most recent night I had the machine set on VAuto.

Below are a couple of shots from the current setting.

Below are shots from last night and the previous night. Not sure why it shows breaks in the AHI graph, but it seems to appear like that quite often. No, I do not turn off the machine when I go to the restroom. You can actually see that in last night's graph at about 3:25 AM.

Would love to hear from either of you your thoughts and impressions after reviewing the screenshots. Thanks

I also created an album and put 4 additional screenshots in showing small time periods where I had event flags throughout different portions of the night. Thought maybe that would help with potentially seeing something I am not seeing or not aware of that I should be. Thanks

Can anyone take a look and let me know if you think things are working or if I'm missing something? Thanks in advance

I've been using CPAP for about 5 months and have not managed to learn much about clear airway/central apneas so far, since I mostly have the obstructive type.

That's definitely odd about your AHI having breaks in the graph. If purging data in SleepyHead and rebuilding doesn't fix it, I don't know what the problem is.

Not much help from here. Oh-jeez

Thanks for looking. The clear air/central apneas are the same thing, just different name. Basically it's when your brain shuts off and doesn't tell your body to breath. From my understanding though they can show up in Sleepyhead from normal things like rolling over or the in between period between awake and sleep.

My main thing is I have lowered my pressure pretty low (3-6) and have been getting low AHI numbers so just wondering if I my graphs show that the lower pressure is helping or if I am just not seeing something in the graphs.

You might start a new thread with a title that mentions CA events and post graphs there. Then people who know more about that type of events would know to look at it.
