Obstructive Sleep Apnea (OSA) is the most prevalent sleep disordered breathing disorder.Â{u9D20} has become apparent that in more than half the patients with OSA, the frequency and duration of apneas are influenced by body position.Â{u052F} treat patients with Position Dependent OSA (POSA), positional therapy can be considered for preventing patients from sleeping in the worst sleeping position.Â{u2963}ently, treatment of POSA has advanced dramaticallyÂ{u7A74}h the introduction of a new generation of positional therapy. Positional Therapy in Obstructive Sleep ApneaÂ{u0CA5}sents improved OSA diagnostic methods and the tools needed to implement positional therapy in clinical practice.Â{u2814}This includes patient work-up, positional therapy with or without other treatments, consequences of guidelines, and future developments. Â{u3B29}inicians, students and researchers will find this comprehensive guide to be an invaluable resource for evaluating and treating sleep breathing disorders.
