In the critically ill elderly patient, multiple organ system involvement is common. The presence of acute--or acute on chronic--cardiac, pulmonary, and renal disease in the same patient makes clinical evaluation for heart failure or volume depletion notoriously difficult. When the clinician is faced with a bewildering array of hemodynamic possibilities in a critically ill patient, the Swan-Ganz catheter may allow a baseline definition of the patient's volume status and cardiac output, on which further therapy and prognosis can be based.
在危重症老年患者中，多器官系统受累很常见。同一患者同时存在急性或慢性基础上的急性心脏、肺部和肾脏疾病，使得对心力衰竭或容量耗竭进行临床评估极为困难。当临床医生面对危重症患者一系列令人困惑的血流动力学可能性时， Swan-Ganz导管可用于明确患者的容量状态和心输出量基线，在此基础上可制定进一步的治疗方案并判断预后。
