Obesity Hypoventilation Syndrome

Obesity Hypoventilation Syndrome: Physiologic Principles and Clinical Practice summarizes the current state of knowledge regarding the epidemiology, physiology and treatment of obesity hypoventilation syndrome (OHS). Currently, the identification and management of OHS is suboptimal, especially in the acute setting, hence the misdiagnosis or mislabeling of the problem has a significant impact on patient outcomes. This volume brings together all aspects of assessment and management into a main resource for understanding the complex physiological and clinical consequences of this condition.

• Provides one page chapter summaries that cover epidemiology, physiology and treatment options
• Presents an easy to use reference on obesity hypoventilation syndrome, including symptoms
• Contains chapters with detailed discussions of topics, including color images, graphs and tables that summarize current research
