Changing the system from measuring blood gases through invasive measures to using noninvasive pulse oximetry is a challenge in the Critical Care Unit where invasive techniques are taken for granted. The authors report a project that was successful in increasing the use of noninvasive monitoring techniques by critical care nurses in a Surgical Intensive Care Unit. This clinical project became an important aspect of incorporating the staff in a change to more extensive use of pulse oximetry. This study defines the change in nursing practice with the use of pulse oximetry. The authors discuss three areas: (1) demonstration of the correlation between O2Sat as measured by the pulse oximeter and arterial blood gas saturations; (2) introduction of the pulse oximeter as a reliable alternative to ABGs when monitoring oxygenation; and (3) the establishment of guidelines for using pulse oximetry within the clinical setting.
在重症监护病房，将测量血气的系统从侵入性方法转变为使用无创脉搏血氧饱和度仪是一项挑战，因为在那里侵入性技术被视为理所当然。作者报告了一个项目，该项目成功地增加了外科重症监护病房重症护理护士对无创监测技术的使用。这个临床项目成为让工作人员参与到更广泛使用脉搏血氧饱和度仪变革中的一个重要方面。本研究定义了使用脉搏血氧饱和度仪后护理实践的变化。作者讨论了三个方面：（1）证明脉搏血氧仪测量的氧饱和度（O2Sat）与动脉血气饱和度之间的相关性；（2）在监测氧合时，将脉搏血氧饱和度仪作为动脉血气分析（ABGs）的可靠替代方法引入；（3）制定在临床环境中使用脉搏血氧饱和度仪的指南。
