Cardiac output, stroke volume, and measurement of other hemodynamic parameters can be useful in the management of critical patients. Given the broad size disparity of veterinary patients, the raw values can vary widely. Their indexed values, however, allow for quick assessment of hemodynamic status and a more standardized target setting by the veterinary care team. Monitors such as lithium dilution cardiac output (LiDCO) and pulse contour cardiac output (PICCO) can display and record the data using indexed values as long as the correct body surface area (BSA) is used. In people, the BSA is calculated using the DuBois formula by entering the patient's weight and height; however, it does not apply to animals because the equivalent relationship is not represented by this formula. Given that the hemodynamic monitors are manufactured for use in human patients, the calculations need to the adapted for veterinary use. As such, the Dubois formula has been rearranged to calculate an assumed height to be entered in the monitor software along with the patient's weight. Once the information is entered, a correct BSA will be calculated by the monitor, and indexed data will be readily available for analysis.

使用LiDCO和PICCO监视器计算狗和猫的体表面积。

心输出量，每搏量和其他血液动力学参数的测量对危重患者的治疗可能有用。鉴于兽医患者的体型差异很大，原始值可能相差很大。但是，它们的索引值可让兽医护理团队快速评估血液动力学状态并设定更标准化的目标。只要使用正确的身体表面积（BSA），锂稀释心输出量（LiDCO）和脉搏轮廓心输出量（PICCO）等监视器就可以使用索引值显示和记录数据。在人中，BSA是使用DuBois公式通过输入患者的体重和身高来计算的；但是，它不适用于动物，因为该公式未表示等效关系。鉴于血流动力学监测器是为人类患者使用而制造的，因此需要将计算结果调整为适合兽医使用。因此，已经重新布置了Dubois公式，以计算假定的身高以及患者的体重，并将其输入到监护仪软件中。输入信息后，监控器将计算出正确的BSA，索引数据将随时可供分析。
