Extremely high CA readings on the ResMed Airsense 11

[Soleil211]

Hello all!

So I’ve been using the ResMed Airsense 11 for a couple of months. My doctor has recognized the need for an ASV when I had a follow up appointment with her a couple of weeks ago. I have yet to receive the machine because the provider that my medical provider is contracted with is disorganized and falls apart over providing anything other than a basic c-pap/a-pap. I’m still attempting to use the c-pap I have in the meantime because I feel like I do feel a bit better, even though I can’t wear it that long because the machine will at some point start furiously blowing air because it doesn’t know what to do with all these CA events.

But my main concern is the amount of CA I’m registering. Last night I was able to use the c-pap for about three hours. My total AHI was 98.9, with OA being 0.7 and CA 97.1. Is this possible??? I would think that I’d have to be having a major health event to register this many CA events. It’s very disconcerting. Just fyi, I have no problem actually using the c-pap, no anxiety or frustration. I have no known health related issues or medications that would clearly cause this. I haven’t checked my data on Oscar yet, but I’m going to be doing that today. Thank you in advance for any helpful feedback.

We have many members here using ASV. If you need ASV, the CPAP is not an alternative and your AHI could be that high. I encourage you to download OSCAR which will let you attach screenshots of your therapy on the forum. We can absolutely coach you that most individuals with CSA that tolerate CPAP need to us a fixed low pressure setting of 6 or 7 cm and turn off EPR or use a low EPR setting of 1. If your DME is having problems delivering an Aircirve 10/11 ASV you should research what providers are in-network for your insurance, and call around on ASV delivery times. Even if the supplier is out of the area, you can get good service and we will help you to get situated. The ASV is nearly completely automatic, and will probably start with default settings of EPAP min 4.0, EPAP max 15.0, PS min 3.0, PS max 15.0, however we will help you to optimize that for your actual needs and comfort.

CA is often idiopathic, which means without known cause, so it does not require comorbid health conditions like congestive heart failure or neurological conditions. It is often the result of a delayed response in the sensors that drive respiration, resulting in a feedback loop of alternating hyperventilation and hypoventilation with central apnea. Please do post a chart of your current therapy, and we'll try to get you as comfortable as possible.
