The blood-conserving technology of continuous intra-arterial blood gas monitoring has recently been introduced into the field of critical care. This type of monitoring is a real-time method for concomitantly assessing oxygenation, ventilation, and acid-base status in pediatric and adult populations through an indwelling (in vivo) sensor residing in a peripheral artery. This article examines the technology underpinning in vivo blood gas monitoring and reviews research documenting clinical performance, as well as benefits and clinical applications of three-analyte systems in critically ill patients. A majority of research has revealed clinically acceptable accuracy and reliability of in vivo blood gas sensors in critically ill adults subjected to a variety of adverse, but common, physiological conditions. Although most clinical research in critically ill adults has revealed good clinical performance of in vivo blood gas sensors, reports of aberrant blood gas values and sensor problems remain; no reports have been published to date evaluating continuous intra-arterial blood gas monitoring in children or infants. Many benefits of this technology have been postulated, and research examining its effect on patient and cost outcomes in critically ill populations is pending. Clinicians in critical care must keep abreast of this emerging technology, because it holds significant potential for improving the quality of care and outcomes of critically ill patients.
连续动脉血气监测的血液保护技术最近已被引入重症监护领域。这种监测是一种实时方法，可通过置于外周动脉的留置（体内）传感器同时评估儿科和成人患者的氧合、通气及酸碱状态。本文探讨了体内血气监测的基础技术，并回顾了记录临床性能以及三种分析物系统在重症患者中的益处和临床应用的研究。大多数研究表明，在患有各种不良但常见生理状况的重症成人患者中，体内血气传感器具有临床可接受的准确性和可靠性。尽管大多数针对重症成人患者的临床研究表明体内血气传感器具有良好的临床性能，但仍有异常血气值和传感器问题的报告；迄今为止，尚未发表评估儿童或婴儿连续动脉血气监测的报告。人们推测了这项技术的许多益处，目前正在进行研究以检验其对重症患者的患者结局和成本的影响。重症监护领域的临床医生必须跟上这项新兴技术的发展，因为它在改善重症患者的护理质量和结局方面具有巨大潜力。
