Espite oxygen being one of the most frequently administered substances in the hospital environment, there is little empirical data regarding its use. Review of the literature regarding the clinical assessment of hypoxia and hypoxaemia reveals inconsistency in the definition of terms and raises questions as to the reliability of the clinical indicators currently used to assess the need for supplemental oxygen. Assessment of the need for supplemental oxygen and continued re-evaluation of the patient's oxygen requirements is a nursing responsibility. Physical assessment, in combination with pulse oximetry, is the most common method used by nurses to assess oxygenation status. This paper critically appraises the literature to examine the reliability of clinical indicators of oxygenation used by nurses in acute care settings.
尽管氧气是医院环境中最常使用的物质之一，但关于其使用的实证数据却很少。对有关缺氧和低氧血症临床评估的文献回顾显示，术语定义存在不一致之处，并引发了对当前用于评估补充氧气需求的临床指标可靠性的质疑。评估补充氧气的需求并持续重新评估患者的氧气需求是护士的职责。体格检查结合脉搏血氧饱和度测定是护士评估氧合状态最常用的方法。本文批判性地评估了相关文献，以检验急性护理环境中护士使用的氧合临床指标的可靠性。
