Cyanide

Wow, running sats that low are not good for you, especially over the long haul. You are kind of leading a path towards stiffening the blood vessels in your lungs (pulmonary hypertension). That isn't all that bad in and of itself (at least to the extent it occurs in OSA) but it does lead to an increased risk of right heart failure. The OSA is probably also dramatically increasing your average blood pressure.

If you can't tolerate the BiPAP or CPAP machines, maybe there are surgical options available (such as cutting out the uvula and part of the soft palate of the posterior mouth cavity)?

I personally alleviated my OSA issue by dropping 30 lbs, but that was my solution...and may not be a part of your issue or solution.

Cheers
