反映体内供氧/缺氧相关指标的意义与临床应用

Significance and clinical application of metabolism-related indexes indicating oxygen supply/hypoxia

氧是维持生命活动所必需的重要物质,临床上很多疾病都会引起氧供需失衡,导致组织脏器受损。临床医生如何应用反映供氧、缺氧的相关指标,早期判断机体有无缺氧及其程度,对于指导治疗、改善预后至关重要。该文就反映供氧和肺氧合功能,以及组织氧代谢的相关指标进行了介绍。

Oxygen is an important substance necessary to sustain life activities.Many diseases would cause imbalance in oxygen supply and demand,thereby leading to tissue and organ damage.It is very important for clinicians to use those indexs reflecting oxygen supply/hypoxia to judge whether the body has hypoxia and its degree in the early stage of illness,which will be beneficial to directing treatment and improving outcome.This paper introduces the indicators related to oxygen supply,lung oxygenation function and tissue oxygen metabolism.
