Two digital oscillometric human blood pressure measuring devices were modified and evaluated as blood pressure monitors in 12 healthy anesthetized dogs. Direct arterial pressures were measured via cannulation of the dorsal pedal artery and were correlated with indirect measurements through an inflatable cuff placed over the dorsal pedal artery below the hock joint of the contralateral limb. Direct and indirect measurements were compared for systolic, diastolic, and calculated mean arterial pressures. Blood pressure ranges between 215/145 mm of Hg and 65/30 mm of Hg were obtained, using combinations of halothane, phenylephrine, calcium, and IV administered fluids. Machine A was found to be insufficient for clinical application, on the basis of correlation coefficients between direct and indirect pressures of 0.78, 0.65, and 0.74 for systolic, diastolic, and mean arterial pressures, respectively. Higher correlation coefficients between direct and indirect pressures (0.77, 0.87, and 0.87, respectively) were obtained with machine B. The results of the study reported here suggest machine B may be an effective blood pressure monitoring device in anesthetized dogs.
对两台数字示波法人体血压测量设备进行了改装，并在12只健康的麻醉犬身上作为血压监测仪进行了评估。通过背侧足背动脉插管测量直接动脉压，并通过放置在对侧肢体跗关节下方背侧足背动脉上的可充气袖带进行间接测量，将两者进行相关性分析。比较了直接测量和间接测量的收缩压、舒张压以及计算得出的平均动脉压。使用氟烷、去氧肾上腺素、钙和静脉输注液体的组合，获得了215/145毫米汞柱至65/30毫米汞柱的血压范围。基于收缩压、舒张压和平均动脉压的直接和间接压力之间的相关系数分别为0.78、0.65和0.74，发现机器A不足以用于临床应用。机器B的直接和间接压力之间具有更高的相关系数（分别为0.77、0.87和0.87）。此处报告的研究结果表明，机器B可能是麻醉犬有效的血压监测设备。
