Pulse oximetry represents a major advance in noninvasive oxygenation monitoring in critically ill adults. Its technology has given practitioners a safe, accurate, and continuous method for assessing arterial oxygen saturation. A comprehensive understanding of the variables of oxygen transport and hypoxemia is essential to ensure correct data interpretation. The accuracy and clinical limitations of pulse oximeters and sensors are presented in this article. The clinical utility of pulse oximetry monitoring in critically ill adults is discussed, with consideration given to patient selection and specific procedures that incur hypoxemic risk. Issues of quality assurance and risk management that surround the use of pulse oximetry are addressed.
脉搏血氧饱和度测定法是危重症成年患者无创氧合监测方面的一项重大进展。其技术为从业者提供了一种安全、准确且连续的评估动脉血氧饱和度的方法。全面了解氧输送和低氧血症的变量对于确保正确解读数据至关重要。本文介绍了脉搏血氧仪及传感器的准确性和临床局限性。讨论了脉搏血氧饱和度测定法监测在危重症成年患者中的临床应用，并考虑了患者选择及存在低氧血症风险的特定操作。还探讨了围绕脉搏血氧饱和度测定法使用的质量保证和风险管理问题。
