초록
Obstructive sleep apnea (OSA) is serious, potentially life-threatening and very common. Untreated OSA can be associated with cognitive impairment, hypertension, heart disease, stroke, increased motor vehicle accidents, and diminished quality of life. Currently positive airway pressure (PAP) is a preferred treatment for OSA. PAP maintains airway patency by creating a pneumatic splint, and then dramatically reduces or eliminates sleep-related respiratory impairments and normalizes sleep architecture. There are three different types of PAP such as continuous PAP, autotitrating PAP, and bilevel PAP. This article will review CPAP treatment of OSA, including mechanism, indication, efficacy, compliance and optimal pressure titration. And alternative therapies such as autotitrating PAP and bilevel PAP will be considered.
