Sudden dramatic increase in AHI. ASV

Post by icipher » Tue Jul 05, 2016 6:25 am

Hello,

I've been on ASV for almost 3 years. I am 32 with no known health issues. I was diagnosed with primarily central, but some obstructive apnea as well. No cause or explanation could be found for the central.

My AHI averages between 1 and 2. It is quite rare for me to see anything past 2.

Last night, I went to bed at my normal time. No alcohol or any medication. I woke up feeling like garbage, to see that my AHI was 5! I have not once seen an AHI of 5 since I've been on therapy.

I took a look at my results and I just see a TON of hypopneas.

Couple questions....

1. Does this merit me going to see my sleep doc whom I haven't seen in over a year?
2. Is it likely that these hypopneas are central or obstructive in nature?
3. Can any other conclusions be drawn from looking at my data?

Since I was never given a cause for my CSA, these increases scare me that it might get worse.

One night of any results - unless you really feel like death itself - is not a reason to panic. Anything could have happened overnight that you didn't wake up to be conscious of - even outside noise, back sleeping, inadvertent bed pillow slippage, a partner's too-close proximity, who knows, and I'd give it at least another 1-2 nights before doing anything about it. Coulda been something you ate and silent GERD popped in.

I agree with Julie...You never want to over react to a one night bump in AHI. Let it go and see what happens over the next few nights.

I appreciate the recommendation not to over-worry.

Normally when my AHI randomly spikes from a normal 1 to say, a 3, I don't worry. The concern here was that I've never seen a 5, or really anything over a 4, in the 3 years i've been on ASV. You'd think that positional changes or GERD would have caused these types of fluctuations before.
