You get my vote for a best answer, but there is way for me to indicate it.
Thanks so much for the information. It is really appreciated.
Hello and hope you are doing well.
Understand your predicament. But it is difficult to predict, as in addition to OSA, other risk factors like hypertension and diabetes need to be considered. According to studies done on OSA patients, this is an estimated incidence rate of 4.4 strokes per 1,000 person years. Besides stroke, low oxygen saturations for prolonged periods can damage vital organs. So, please try to get alternate masks to continue with your CPAP. You can even talk to your doctor for supplemental oxygen therapy to correct the low saturations.
Hope this helped and do keep us posted.
