The process of pulmonary artery pressure monitoring in 50 consecutive patients in the surgical intensive care unit was analyzed to determine the number and types of problems that occurred in relation to the benefit obtained. Twenty-six percent of the patients had a change in their cardiorespiratory therapy and their conditions were improved after the pressure data were obtained. Many technical and interpretative problems that tended to decrease the desirability of using pulmonary artery pressure monitoring were identified. Most problems could be avoided by carefully calibrating the monitor system, clearing the catheter system of air bubbles and blood clots, learning to property interpret pulmonary artery pressure tracings despite large respiratory variations, and obtaining a hard-copy printout of the pressure tracing with the simultaneous ECG signal. A protocol for avoiding many difficulties was developed.
分析了外科重症监护病房连续50例患者的肺动脉压监测过程，以确定与所获益处相关的问题数量和类型。26%的患者在获得压力数据后心肺治疗方案发生了改变，病情得到改善。发现了许多往往会降低使用肺动脉压监测可取性的技术和解释性问题。通过仔细校准监测系统、清除导管系统中的气泡和血凝块、学会在呼吸变化较大的情况下正确解读肺动脉压描记图以及获取带有同步心电图信号的压力描记图硬拷贝打印件，大多数问题是可以避免的。制定了一个避免许多困难的方案。
