New member here. I apologize if this question has been asked; I have searched here and elsewhere and can't find the answer.
I've been using CPAP for almost two mos. I was diagnosed by sleep study with mild OSA (AHI), oxygen desaturation (78%), and severe periodic limb movements. I got a ResMed S9 Elite with Swift Bella nasal pillows. My first week my AHIs were in the 2-4 range and I felt great. Since then, my AHIs have been increasing. They are usually between 5&10, but I've had some as high as 15-18. Saw the Pulmonary doc after six weeks and my average AHI was 6.3. He was not concerned, but decided to increase my pressure from 9 to 10 when I told me I didn't feel as good. No evidence of leak issues, but I tried a chin strap anyway for a while, and it made no difference.
I definitely feel better when my AHI is well under 5. Am I crazy? Doc says there's really no evidence that an AHI of 5 vs 2, for example, should affect how I feel.
My AHI continues to vary quite a bit, and is rarely under 5. Why is that? Why did I do so much better in the beginning and then get worse? BTW, the AHI has improved some since pressure was increased--I've had no numbers over 10.
Thanks in advance.
