I am 44 and was diagnosed with OSA 1.5 yrs back . My first sleep study revealed my AHI was 40. I was tested with CPAP on and the AHI came down to 2.9 . Since on CPAP then, My AHI is pretty much below 2 . From last 2 weeks , I see my AHI is between 3 to 5.5 . Wondering what caused all of a sudden. for last 2 weeks , I am waking up with a feeling that the pressure is high and feeling of suffocation. When i check in the morning , the Max pressure is between 13 to 14 range.
I use Resmed s9 autoset and the machine is set to auto
I did an echo yesterday and the PAP was 45mmHg. I have been doing PAP for last 4 yrs . 4 yrs back was 35, then 30 , then 35 and this time 45 . Last yr PFT showed my
lung capacity as 72%. 4 yrs back it was 62%. I quit smoking and that improved my Lung capacity . Also PFT revealed mild restriction and did a CT of lungs 4 yrs back and everything came out normal . Restriction is there every time I do PFT .
Family history, My Mom had ILD and passed away and My Dad has COPD and he is so far doing ok .
I will be meeting my Pulmo soon, But want to hear if anyone in the same boat or any expert comments as I am little concerned .
Thanks in advance
