"CPAP" stands for continuous positive air pressure. This machine provides a "steady" flow of air in order to keep breathing passages open. Depending on the air pressure necessary in an individual case, some people have difficulty exhaling against that level of air pressure. "Bi-PAP" stands for bilevel positive air pressure. These machines set one pressure for inhalation (IP) and another lower pressure for exhalation. "Automatic" or "Variable" pressure machines are supposed to elevate air pressure only when needed to keep an air passage open and stay at a relatively low air pressure unless triggered to elevate by the machine's sensing devices.

yes you need it after surgery. Please tell your doctors you have sleep apnea. I was told that it makes a difference on how they treat you during surgery. I used mine with no problem after my surgery.
