Is my cpap causing me to have central sleep apnea? i was diagnosed with osa but i slow down breathing on my cpap, its scary!

Maybe: If your breathing is just slowing, that is not necessarily a bad thing. Central apneas are when you don't breath and you don't try to breath. Did you have a CPAP titration trial in the a sleep center, or a home sleep test? Either way there would have been a recording of your sleep with your cpap.

Not likely: When you have osa your heart rate and rate of breathing can increase. When using your cpap, you are getting a better blood level of oxygen which means your breathing can slow down. With central sleep apnea, you would stop breathing just as with osa. There are usually other health problems occurring when you have central sleep apnea. Don't worry about central sleep apnea if you don't stop breathing.
