I was diagnosed with sleep apnea in November. Started on a cpap in December and once I started wearing it I was able to do more. However, in the last month breathing became harder..seemed I was always out of breath. Have been to a cardiologist, asthma doctor, allergy doctor, pulmonary doctor. I took a chemical breathing test that indicated I do not have asthma although I was treated aggressively for asthma before the cpap. I slept with a gadget on my finger that said I was below 89% oxygen intake 36% if the night. Now I am told by the pulmonary doctor that I am going to have oxygen added to my cpap. I am a bit overweight but not obese. Every one tells me different things. Going to an ENT tomorrow. Not sure what direction to go next. Any suggestions?
