Tu1257 The Ramsay Sedation Scale Score Is a Poor Predictor of Abnormal Ventilation During Endoscopy Using Moderate Sedation

Abstract

Abnormal ventilation during endoscopic sedation can be identified by the occurrence of hypoxemia detected during pulse oximetry, but only if the patient is not on supplemental oxygen. Patients at moderate sedation levels are presumed to have intact ventilation and airway protection reflexes. Clinical assessment scales, such as the Ramsay Sedation Scale (RSS) are often used during endoscopy to monitor whether a patient is at moderate or deep levels of sedation. It is unclear how such scales perform in predicting the occurrence of abnormal ventilation during endoscopy.
