Now I have between 0 and 2 apnea events per night, but my hypopneas have gone up to as many as 30 per night. My AHI has gone up from as low as 1.1 up to as much as 6.4, with the new average of 3.0. I understand that this is not a "bad" average number, but I do not feel well again. I have frequent headaches, my energy is low and I am sleepy again in the daytime.
There have been no changes in pressure or humidity in several months.
Why would the number of hypopneas suddenly go up? Is this significant, or should I just worry if the apnea numbers go up?
I looked up the definition and see that hypopnea means slow or shallow breathing, I just don't understand how this fits with the whole obstructive sleep apnea diagnosis at this point when there are almost no flow limitations or apneas showing up on my charts?
Does anyone have any ideas?
