I have sleep apnea, AFIB, history of blood clots and taking Xarelto. I use a BiPAP with full face mask. I'm currently scheduled to have septoplasty and turbinate reduction. My ENT said he was ok with me using my BiPAP. But he also said I will have some congestion for up to a week. I can't go one night without CPAP, due to my AFIB heart condition. I've had conflicting answers from other ENT's stating I would need to hold off the BiPAP for a few days.
