CPAP, or Continuous Positive Airway Pressure, delivers pressurized ambient air (regular room air) through a delivery system (tubing and mask), thus eliminating apnea events during sleep. CPAP is the most effective treatment for sleep apnea and can potentially improve the patient’s sleep overnight; dramatically improving the quality of life for individuals afflicted with obstructive sleep apnea
CPAP is the most common PAP device. If you had a sleep study and a titration in a sleep center, this probably the type of PAP machine you will be recommended. Many sleep specialists agree that the fixed pressure is best for treating obstructive sleep apnea and it’s the most affordable device.
BiPAP, or Bi-Level Positive Airway Pressure, is another form of sleep therapy, which delivers alternating levels of a higher inspiratory pressure (IPAP) to keep the airway open as a patient breathes in, and a lower expiratory pressure (EPAP) allowing the patient to exhale easily. Thus, a BiPAP is much easier for users with neuromuscular disease to adapt to. The dual settings allow patients to get more air in and out of the lungs without the natural muscular effort needed to do so.
