Why change from cpap to bipap

I was changed from cpap to bipap. Why would some need to change?

I suspect that since there might be more than one reason and only one specific to your medical needs, chatting with the doctor who changed the prescription might reveal the answer most accurately.

Thanks, after reading several post. I now have a better understanding. Jim B

The advantage of BiPAP/BiLevel is a lower exhalation pressure and for people with COPD or similar this makes therapy much more comfortable. I use a BiLevel machine for my therapy even though I don't have any respiratory issues. What it does for me is make xPAP therapy a better experience. Yes, I happily worked with APAP but BiLevel feels better and it has also lowered my AHI numbers.

I am being put on one because I am maxing out the apap that I was loaned from the clinic. They wanted to get me something with extra pressure in case I need it down the road.

CPAP and BiPAP are different devices for treating different problems. A BiPAP is not just a more comfortable or higher pressure form of CPAP, although they are sometimes used in this way. If your doctor wants to swap you from one to the other, make sure that they explain to you, in as much detail as you need, why they are doing so. It is their job to educate you about your medical situation and why they wish you to use particular treatments. Make them earn their money.
