A pulse contour method for cardiac output determination was evaluated in sixteen cardiac surgery patients. Stroke volume was derived from the aortic pressure waveform by means of a formula developed by Wesseling and was calculated with an in-built computer (Philips cardiac output module). The method was used for continuous postoperative monitoring and was compared with thermodilution cardiac output determinations. The overall comparison of data (71 simultaneous measurements) yielded a correlation coefficient of 0.78 (regression y = 0.81 x + 1.07 liter) (p less than 0.001). Advantages and disadvantages of the pulse contour method are discussed.
对16名心脏手术患者评估了一种用于测定心输出量的脉搏轮廓法。通过韦塞尔林提出的公式从主动脉压力波形中得出每搏输出量，并使用内置计算机（飞利浦心输出量模块）进行计算。该方法用于术后连续监测，并与热稀释法测定的心输出量进行比较。对数据的总体比较（71次同步测量）得出相关系数为0.78（回归方程y = 0.81x + 1.07升）（p<0.001）。讨论了脉搏轮廓法的优缺点。
