Comparison of intraarterial pulsegraphy and standard thermodilution methods for determination of cardiac output (CO) in 14 patients with poor cardiac function following valve replacement operation was performed. The CO, cardiac index (CI) were moderate to high correlated between the two methods before and after valve replacement respectively. The study indicates that intraarterial pulsegraphy provides a continous method of determining CO in patients with poor cardiac function during operation.
对14例瓣膜置换术后心功能较差患者，进行了动脉内脉搏图法与标准热稀释法测定心输出量（CO）的比较。两种方法测定的CO和心脏指数（CI）在瓣膜置换术前、后均分别呈中度至高相关性。该研究表明，动脉内脉搏图法为术中测定心功能较差患者的CO提供了一种连续的方法。
