Zee, and Frances F. Chung; on behalf of the ATS Assembly on Sleep and Respiratory Neurobiology THIS OFFICIAL WORKSHOP REPORT OF THE AMERICAN THORACIC SOCIETY WAS APPROVED OCTOBER 2017. This official American Thoracic Society Workshop Report was endorsed by the Canadian Sleep Society November 2017 and by the Canadian Thoracic Society December 2017. Abstract OHS in the perioperative setting to achieve these objectives. Patients who are at greatest risk of respiratory or cardiac complications related The purpose of this workshop was to identify knowledge gaps in the to OSA and OHS are not well defined, and the effectiveness of perioperative management of obstructive sleep apnea (OSA) and monitoring and other interventions remains to be determined. obesity hypoventilation syndrome (OHS). A single-day meeting was Centers involved in sleep research need to develop collaborative held at the American Thoracic Society Conference in May, 2016, with networks to allow multicenter studies to address the knowledge gaps representation from many specialties, including anesthesiology, identified below. perioperative medicine, sleep, and respiratory medicine. Further research is urgently needed as we look to improve health outcomes for Keywords: obstructive sleep apnea; perioperative care; obesity these patients and reduce health care costs.
