CPAP therapy otherwise known as constant positive airway pressure is the gold standard choice in the treatment of obstructive sleep apnea boasting a significantly higher success rate 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 similar to 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. Most patients become accustomed to use and gradually become unaware or unbothered by the therapy.
