What Are BiPAP & CPAP?
BiPAP stands for Bilevel Positive Airway Pressure, and CPAP stands for Continuous Positive Airway Pressure. Both are masks used for the treatment of sleep apnea, an obstructive condition that causes an individual to stop breathing while sleeping. Sleep apnea affects millions of people, and often results in inadequate oxygenation that leads to headaches and interrupted sleep patterns. People diagnosed with sleep apnea often require sleep apnea masks in order to maintain adequate oxygenation. Masks create a continual flow of oxygenated air hooked to a hose via a machine that provides the brain and body tissues with vital oxygen.

BiPAP
-
A BiPAP machine provides two flows of constant air pressure, one used for inhalation and another for exhalation. The airflow for exhalation is created using a lower pressure than the one for inhalation. The BiPAP machine is preferred by many doctors and patients over the CPAP machine, as it allows for easier exhalation. People diagnosed with chronic obstructive pulmonary disease or neuromuscular disease processes also prefer the BiPAP, as it creates an easier, smoother breathing process.
CPAP
-
The CPAP machine is a single-airflow machine that offers a constant flow of oxygen. The air gently forced through the machine enters a patient's nose and mouth (through a mask), which prevents the throat from relaxing to the state where breathing may stop.
BiPAP and CPAP Masks
-
BiPAP and CPAP masks are designed to fit over the nose and mouth. The CPAP mask generally fits over the nose, while the BiPAP mask fits over the nose and mouth. Both are are held in place through headgear straps. CPAP masks are made of silicon that seals over the nose, while many BiPAP models are created with gel-filled masks and seals that provide additional comfort.
Use
-
Both the CPAP and the BiPAP sleep apnea masks may be used for individuals diagnosed with mild to moderate sleep apnea. Most often the CPAP mask is used with those suffering from upper respiratory issues, while the BiPAP is used by people with moderate to severe obstructive problems.
Design
-
Both the CPAP and BiPAP sleep apnea masks are electric machines with built-in compressors. A long, lightweight hose connects from the compressor to the nasal or mouth mask. The treating doctor will determine the air pressure to be set for either, and different features may be offered depending on need.
