ASV and hypopneas

RE: ASV and hypopneas
In your case hypopnea should be addressed by a breath by breath pressure support. It would help to see the mask pressure chart under the flow chart to see the machine's real-time response. I'd like to see that before making a recommendation, but I think you might decrease PSmin to 2.0 and increase PSmax to 11.0. This might reduce the events you are experiencing and give a more pronounced support when those shallow inspirations occur.

RE: ASV and hypopneas
The chart shows the machine is delivering the maximum available PS during shallow hypopnea breaths. I think the suggestion to use a lower minimum PS and higher maximum PS may help. Give it a try and let's see if things smooth out a bit. The idea being that you get more contrast in PS assisted breaths vs natural spontaneous breaths.

RE: ASV and hypopneas
Hi Sleep Rider,
The changes you suggested worked. I increased the maximum PS by a couple of inches and dropped the lower PS a bit. I had one night of an AHI of 0.8. Thanks so much! My AHI is running mostly about 2.0. My doctor is only concerned about hypopneas that decrease my O2 levels. I used the O2 attachment for 4 nights and found the hypopneas did not drop the O2, but periods of high leak rates do. It also seems I get hypopneas when I have a period of excessive leaks so I'm working on that now. I will go back to a full face mask possibly to see how that does, but a full face mask can leak around the edges too. The leak alarm did not help. It seems like someone would create an aftermarket leak alarm that would be adjustable and audible. I would appreciate any ideas you may have. Thanks much!

RE: ASV and hypopneas
I'm really glad to hear the minor changes worked for you. So often, it's nothing radical, but working towards a comfortable and logical solution.
Same thing with leaks...resistance is futile...Resmed Airfit P10.

RE: ASV and hypopneas
Very interesting. I just saw a YouTube video of the ResMed Airfit 10. I thought I might see if my supplier would let me try on of those. Now I definitely will! Thanks!

RE: ASV and hypopneas
Airfit P10 is my recommendation also. Out of all the masks I tried it was definitely the best for me. In all respects.

RE: ASV and hypopneas
Thanks for your feedback Marillion,
Well, I was going to try the F10 or F20, since the one time I tried a nasal pillow, admittedly a long time ago, I could not tolerate the pressure on my nose. Is the P10 similar to other pillows? I think I tried a ResMed nasal pillow about 10 years ago. |
