RT Journal Article SR Electronic T1 The Obesity Hypoventilation Syndrome JF Respiratory Care FD American Association for Respiratory Care SP 1723 OP 1730 VO 53 IS 12 A1 Mark Anthony Powers YR 2008 UL http://rc.rcjournal.com/content/53/12/1723.abstract AB We only need to look around us to see that we are in an epidemic of obesity and obesity-related medical problems. The obesity hypoventilation syndrome is a disorder in which an obese person with normal lungs chronically hypoventilates. Obesity impairs ventilatory mechanics, increases the work of breathing and carbon dioxide production, results in respiratory muscle dysfunction, and reduces ventilatory response to hypercapnia. Sleep-disordered breathing is present in most patients with the obesity hypoventilation syndrome. When noninvasive ventilation can be successfully introduced, hypoventilation can usually be corrected. Weight loss is the desirable long-term treatment for the obesity hypoventilation syndrome. This paper concisely overviews the physiologic factors that lead to the obesity hypoventilation syndrome and discusses therapies for it.
