I was recently (2 months ago) diagnosed with severe sleep apnea with an AHI of 102 during my sleep study. The doctor mentioned that it seemed to mostly consist of Central SA with some instances of obstructive SA. I purchased an Airsense 11 APAP and they set it to a range of 5-20, according to my GP who ordered the sleep study.
I noticed my AHI went down to 5-10 but I couldn't sleep with the full face mask. I bought the nasal mask and it fit well but I still had some difficulty falling and staying asleep. I finally went with the nasal pillows however I noticed my AHI reached 20-30. I went back to the nasal mask and it still keeps climbing. Last night it was at 52.67.
I notice when I start to nod off, I just stop breathing and honestly, I'm feeling pretty terrified. I just had a procedure done on my heart to correct an AFib and I get arrhythmias and tachycardia when my AHI is this high.
Can anyone shed any light on the situation? I'm going to schedule an appointment with a doctor / sleep specialist but it's Sunday today.
