主　　题：Oxygen reserve index(ORI) Oxygenation Pulse oximetry Monitoring Hyperoxia 

摘      要：The oxygen reserve index(ORI)is a new technology that provides real-time,non-invasive,and continuous monitoring of patients’oxygenation status.This review aimed to discuss its clinical utility,prospect and limitations.A systematic literature search of PubMed,MEDLINE,Google Scholar,and ScienceDirect was performed with the keywords of“oxygen reserve index,“ORI,“oxygenation,“pulse oximetry,“monitoring,and“hyperoxia.Original articles,reviews,case reports,and other relevant articles were reviewed.All articles on ORI were selected.ORI can provide an early warning before saturation begins to decrease and expands the ability to monitor the human body’s oxygenation status noninvasively and continuously with the combination of pulse oximetry so as to avoid unnecessary hyperoxia or unanticipated hypoxia.Although the technology is so new that it is rarely known and has not been applied to routine practices in hospitals,it shows good prospects for critical care,oxygen therapy,and intraoperative monitoring.
