Three cases studies are presented to demonstrate clinical application of mixed venous oxygen saturation (SvO2) monitoring in critical care nursing practice. Examples of critically ill patients are used to demonstrate how SvO2 monitoring can be used in clinical practice to reflect an imbalance between oxygen delivery and oxygen utilization. In the first case, the patient had a problem with oxygen delivery. Continuous SvO2 data aided nurses in guiding, adjusting, and assessing therapy. The second case demonstrates how SvO2 monitoring can provide an early sign of a life-threatening complication. The final case is one in which the patient had a problem with oxygen utilization. In all the cases, continuous SvO2 data provided important information about the balance between oxygen delivery and oxygen utilization.
本文呈现了三个案例研究,以展示混合静脉血氧饱和度(SvO2)监测在重症护理实践中的临床应用。通过重症患者的实例,展示了SvO2监测如何在临床实践中用于反映氧输送与氧利用之间的失衡。在第一个案例中,患者存在氧输送问题。连续的SvO2数据帮助护士指导、调整和评估治疗。第二个案例展示了SvO2监测如何能提供危及生命并发症的早期迹象。最后一个案例中,患者存在氧利用问题。在所有案例中,连续的SvO2数据提供了有关氧输送与氧利用平衡的重要信息。
