Very interesting. I'm definitely going research more on this. Bi-pap seems vastly superior.
Thank you for your thorough reply.
It depends on how much pressure is needed to keep your air passages open when you inhale.

20. I need 13. When the pressure necessary gets very high, your lungs have trouble exhaling. So a BiPAP becomes what you need. It lowers the pressure so your lungs can exhale more completely, and then raises it for the inhalation.
I have not much trouble with a straight simple CPAP personally. My trouble was my original doctor insisted on me using the mask, which made me feel my breath on the tip of my nose. I could not make him understand that that bothered me so very much.
I put the thing in the closet for two years until I couldn’t stand it anymore. I went to a different doctor and he immediately wrote me a prescription for a nose pillow headpiece and chin strap. It took me just two days to get accustomed to that.
It was wonderful that first night. When you have apnea, many guys thrash their legs when they sleep and their bed linen is all disheveled when they wake up. When your CPAP first works you know it has worked because your sheets and blankets are just as you left them when you went to sleep. And you are left with a wonderful feeling that I can’t possibly describe.
