The gold standard in canine blood pressure (BP) measurement is the invasive method; however, non-invasive blood pressure measurement techniques (NIBP) are more commonly used. The lack of small, lightweight, cheap, fast and portable NIBP still remains a point to improve in the emergency setting.
A human wrist blood pressure (WBP) device was evaluated in comparison with the veterinary high-definition oscillometry (HDO) in conscious normotensive dogs. Systolic and diastolic BPs were evaluated in two groups of dogs. The bias, the limits of agreement and correlation between variables were calculated. Twenty-five and 36 dogs were, respectively, included in Study No. 1 (dogs weighting ≥10 kg) and 2 (dogs weighting ≥20 kg). In both studies, correlation between the two devices was moderate. A better agreement was displayed for diastolic pressure and poor precision for both systolic and diastolic pressures measurements (as determined by wide limits of agreement). The WBP method underestimated both the systolic and diastolic BP with respect to the HDO method. The inclusion of bigger dogs (Study No. 2) with limb circumference more like to human limb dimension did not improve the agreement between considered methods.
The human WBP monitor considered is not suitable to replace the commonly used veterinary HDO for in-clinic BP monitoring in normotensive conscious dogs.
犬血压（BP）测量的金标准是有创方法；然而，无创血压测量技术（NIBP）更为常用。在紧急情况下，缺乏小型、轻便、廉价、快速且便携的 NIBP 仍然是需要改进的一点。
在清醒的正常血压犬中，评估了一种人类腕部血压（WBP）设备与兽医高清振荡法（HDO）的比较。在两组犬中评估了收缩压和舒张压。计算了偏倚、一致性界限和变量之间的相关性。第 1 项研究（体重≥10kg 的犬）和第 2 项研究（体重≥20kg 的犬）分别纳入了 25 只和 36 只犬。在这两项研究中，两种设备之间的相关性为中度。舒张压的一致性较好，而收缩压和舒张压的测量精度较差（表现为较宽的一致性界限）。WBP 方法相对于 HDO 方法低估了收缩压和舒张压。纳入肢围更接近人类肢体尺寸的较大型犬（研究 2）并没有改善所考虑方法之间的一致性。
所考虑的人类 WBP 监测器不适合替代常用的兽医 HDO，用于正常血压、清醒犬的临床 BP 监测。
