AUtosense 11 problems

Post by bucko » Tue Jul 26, 2022 8:25 am

My numbers not so good and I would like some feedback please.
First graph is usage out of the box. DME pressure set 5-19. Next graph I changed pressure to 8-18 like I had with my dreamstation.
I find the Resmed air hose is quite stiff and aiding in my mask being pushed around causing large leaks. My AHI are looking good until the leaks happen and my pressure starts going up.
Last graph I wake up 3am with air pushing out all around my mask as pressure was at 16. I cycled off machine to get it to restart at 8 where it appears things went back to good (AHI numbers) and events went away. So in my opinion, my main issue is my mask leaks I think due to the stiff hose. You experts please correct me if Im wrong. I'm far from an expert with Oscar. Any suggestions?

I do think that the mask leaks most likely caused your sleep to be disturbed and the flagged events you see with the increased leaks and large leak flagging are from awake breathing false positive events. You most likely weren't sound asleep due to the leaks. So the increased AHI is from leaks disturbing sleep.
Watch the videos here to get an idea what I am talking about. While the videos are mainly talking about CAs/central apneas...it can happen with any apnea event category.

Ignore for now and put all the blame on leaks. When you fit your mask at the beginning of the night did you use the mask fit feature or just put it on and fit to the starting pressure of 8?
The fit or seal needed at 8 cm is not likely going to work well with a pressure in the teens.

This machine won't try to "fix" a leak with more pressure...it just doesn't work that way. Now what caused the machine to want to go to close to 18....I don't know...usually it is the flow limitations that is the culprit but while your FL graph is a bit active it doesn't appear to be all that horrible.
When you woke up with the pressure so high and leaks....were you on your back perhaps?

Which hose are you using with the new machine? The heated hose or the non heated hose? If non heated hose is it the slimline smaller diameter hose or the standard size hose?
Yes, ResMed hoses can be a bit stiff but usually with a bit of time they loosen up but there are ways to accelerate the process.

In the 2nd graph I purposely started slept on my stomach. I don't remember if I was on my back when I woke up.
I did do the mask fit on the machine and it reported the fit was good. I use the heated hose set on auto and the humidifier also at auto.
Tonight I am going to try the nasal pillow mask and chinstrap. I always have the problem of my mouth opening up when I am sleeping which is why I always used a FF mask.

I am going to set my EPR back on (1) and use the nasal pillow mask tonight and see if it makes a difference.

If you wake up in the middle of the night again with higher pressures...try to make a mental note if you were on your back or not.

2 things can cause OSA to worsen and higher pressure needs
1...supine sleeping
2...REM stage sleep ....and your little cluster of events and higher pressures could very well be REM related. I have REM worse OSA myself...about 14 AHI on diagnostic test in non REM sleep but in REM sleep I had a 53 AHI and I often need a lot more pressure in what is probably REM. Google "sleep stages" and look at the normal hypnograms and see when REM occurs.
Your cluster is smack dab in the middle of when we have the greatest amount of REM.

Last night I tried to sleep on my side and I used my Airfit P10 mask for the 1st time. It left me with a little sore nose and a dry mouth in the morning, but my chin strap did fall off a few times in the night.
I did set my EPR to 1 fulltime and set min at 9.
My AHI did fall but I can't say I felt a great deal better after waking up. Maybe through the day I will notice more about that.
Do you see anything ?

I see lots of leaks probably associated with mouth opening/breathing.
Enough that they probably also disturbed your sleep as well which that in itself is enough to make us feel like crap.

Your AHI is just about half and half obstructive and central.

I am wondering how much of your flagged events are real asleep events or were false positive flagging from arousals that you may or may not remember.

I suggest you take a crash course on evaluating the flow rate for spotting evidence of arousal/awakenings.

Now all that said....look at the pressure graph...again much higher in the later hours....sure makes me think of REM.
Not much we can do about REM...we need it.

You had a leaky night with a new mask last night. I would give the new mask more time and try to fix the chin strap so it does a better job or maybe even consider taping for one night.

I tried he large pillows on the P10 with chinstrap. I also dabbed a little vicks on my nose before using. In the morning my nose irritation was only slight which went away quickly and I only had dryness under my upper lip. Best feeling so far after sleep. Not perfect, but I felt as if I actually slept. No brain fog in the morning.
In my opinion it looks like I'm getting closer to good therapy now. I believe my mouth leaks seem to be the main issue with me. I have a very cheap chinstrap I use that I should upgrade, but I am encouraged it's going in the right direction now.
What do you think?

Moving in the right direction. You say you feel you slept better and feel a bit better and the numbers seem to reflect that as well. That's what we want to hear.

You already know you need to work on the mouth leaks a bit more but what you see from last night isn't horribly horrible.
25% of the time in large leak and part of it was barely over 24 L/min.
ResMed still gives you a Mr Smiley for leak management since you didn't hit 30% of the time.

Wow, I feel very good finally! I think with your help Pugsy, things are dialed in good now. I used EPR at 3 last night with the P10 and got this result. My problem is definitely mask leaking.
However I am going to replace my mask with an Airfit N20. the P10 is getting a lot better to use, but I don't like the feel of the pressure on my nostrils.

Thank you for all your help. :D

I just wanted to end this thread with good news. Last night my AHI is 0.75. It looks like I'm dialed in now finally and feeling 100% better.
