Continuous Positive Airway Pressure, also known as CPAP is a method of taking positive pressure and applying it inside the throat in order to keep it from collapsing while you are sleeping. The mask is worn over the nose and hooked up to a CPAP pump. The pump then applies pressure to keep your throat from collapsing. The BiPAP machine allows the air that is delivered through the mask to be set at one pressure for inhaling and another for exhaling. This makes BiPAP much easier for users to adapt to. These dual settings also allow people who use the device to get more air in and out of the lungs.

AutoPAP - An automatic continuous positive airway pressure (CPAP) machine, also known as an APAP or AutoPAP machine, is a device used to treat sleep apnea. The Auto CPAP machine is designed to provide air pressure at a customized, regularly adjusted level, while the traditional CPAP machine provides air pressure at a constant level. An auto CPAP machine, like any CPAP machine, must be prescribed by one's doctor. Home sleep testing is roughly one-fourth the cost of laboratory testing. The use of an auto-titrating CPAP machine can eliminate the need for a lab sleep study.
