RESUMEN

Biological age has been proved to be better than chronological age to measure the real difference of aging among individuals, but no consensus has been reached in the quantification of biological age in the field of aging research. In this paper, we summarize some commonly used quantification methods of biological age and discuss the its future development.

RESUMEN

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.
