 Obstructive sleep apnea, OSA, is a common condition with serious health consequences. It can lead to poor quality of life, reduced productivity, increased risk of accidents, and even death. Research has identified several different types of OSA, each with their own unique characteristics. Treatment options include positive airway pressure, PAP, as well as various non-PAP treatments such as surgery, oral appliances, and medication. While PAP remains the gold standard for treating OSA, non-PAP treatments have been shown to be effective in some cases. More research is needed to determine which treatments are best suited for which patients. This article was authored by Winfried Randerath, Jan Dalanga, Jan Hetner, and others.
