Question: Using a CPAP cause sleep apnea if you may no longer need to use one?When I was first diagnosed with sleep apnea in the summer of 2005 I eighed 280lbs and smoked 1 1/2 packs of cigarretts a day. I had 117 episodes per hour. I was given a CPAP machine set at a pressure level of 10. Since then I have quit somking, over a year know, and now weigh 225lbs on my way to 200lbs. I am still using the CPAP though set at the same pressure. The problem is I am starting to feel tired again during the day. Not to the level it was before I started therapy, but I can feel a difference. I made an appointment with my doctor but the earliest she can see me is July. I was wondering if anyone knew if I am actually causing sleep apnea or something similar by using the machine?
Answer: In general, no if your CPAP machine is too high it will not cause you to have obstructive apneas. It could be causing you to have more arousals. And this is differently the reason that you feel more tired than normal. I don't understand why your doctor can not get you in to see her until July, I would call and request to talk with her. B/c it seems that you would need to have a CPAP Retitration to firgure the amount of cm you need. Congratulations on quiting smoking.
