I have snored loudly for as long as I can remember. I've had complaints from people not even in the same room and some evil glances from fellow travelers on the rare occasions I've fallen asleep on a plane. After a bad nights sleep I can feel my soft palate is loose when I swallow - I guess due to the snoring. The snoring, coupled with my stopping breathing during the night, plus feeling increasingly tired at work, eventually prompted me to go to the doctor.
I was given an overnight home test with a basic meter that gave an indication of 18 events per hour. A nose exam revealed a restriction that they now want to examine under general anaesthetic. I then had a home PSG done. This showed:
AHI 32.8>Central Apnoea 42(4.7)>Obstructive Apnoea 0>Central Hypopnoea 129>OH 1>Undefined H 121> Total Apnoea 42(4.7)> Total Hypopnoea 251(28.1)> Min O2 87%> O2<90% 00:05:06> Mean O2 95%> Heart Arrhythmia 39(4.7)> Snore 1213(135.7)> Sleep Efficiency 89.4%
This came as a bit of a shock as I was told all previous indications had pointed to OSA being the cause of my sleeping worries. I was given an ResMed 10 Autoset, initially to be used in auto but changed to fixed pressure by the person who delivered it and set it up. I have only used it one night so far but found that it has dropped the AHI to 0.3> Total AI 0.1> CA 0 >Leak 11Lpm. This is just with the initial setting of 6.6cm fixed pressure and no adjustments made! Can it really have made so much difference so quickly? I didn't feel like I slept well (woke up a couple of times, only slept for 6 hours) but that is probably me adjusting to sleeping like Darth Vader. From what I've read on internet (a doctor's favourite phrase) it seems like a CPAP can only have no or negative effects on CSA, contrary to what the sleep specialist has told me.
Anyway that is all my info. As I have only had it one night I will let it build up a bit more data before I use the analysis software (my care provider wanted to charge me around $80 for it....).
This board has already been invaluable as I travel around a lot with work and have to visit doctors of varying levels of interest in various countries. Often the language barrier makes things more difficult too. It's good to have an online resource for all this new information. I have found the somewhat blase and contradicting information I've been given by my care provider to be a bit worrying.
Thanks to you all for all the info I've already got from this site.
