Otherwise known as constant positive airway pressure, CPAP therapy is the gold standard choice in the treatment of obstructive sleep apnea with significantly higher success rates than corrective surgery or dental appliances in moderate to severe cases. A pressure is applied gently to the airway to relieve flaccid anatomical muscle tone during sleep through an externally affixed mask. The patient’s perception is that like a fan, that translates into an airway splint or pressure to keep the airway open during sleep. Through repetitive use and as their pre-treatment symptoms subside, improved breathing is achieved.
