Positive Airway Pressure (PAP) machines are the most widely used and most effective treatment for obstructive sleep apnea (OSA), even for moderate and severe apnea. The machine connects to a mask, and air flows continuously to prevent the airway from collapsing. An Auto-CPAP automatically adjusts the air pressure when you experience an apnea.
PAP devices are covered by most medical insurance plans, and your physician can order from a DME or Durable Medical Equipment provider in your area. The will have therapists available to fit you with a mask and answer questions.
