You are/were smoker?: Sleep apnea can cause drop in oxygern during the night, but should be relatively normal during day (because you are breathing normally during day). Are you or were you a smoker? Copd/chronic obstructive pulmonary disease can be cause of low o2 saturation. So, i would check with doc to find out why. A cpap/bipap is recommended for sleep apnea. I am glad your heart checked out ok. Good luck.

Sleep apnea: Sleep apnea is defined as stopping breathing for at least 10 seconds and having blood oxygen levels drop below 90%. If you know you have sleep apnea, why haven't you been advised about either CPAP or custom dental device to open the airways to allow proper oxygenation? Please discuss this with your md asap!. You are at risk for heart attack, stroke, high blood pressure, diabetes and more.

Sleep specialist: Most people who have sleep apnea don't know they have it because it only occurs during sleep. During the day your SatO2 is normal. Only a sleep study in a sleep laboratory or a home can show definitively that sleep apnea is present or not. See a sleep specialist for consultation.
