The reproducibility of indirect measurements of arterial pressure in dogs was assessed using the Dinamap 1846 SX oscillometric monitor and tail cuffs. Measurements on different days correlated excellently in 20 working dogs, with indistinguishable group means for systolic, diastolic and mean arterial pressure, whereas heart rates differed, though not significantly. The similarity of the means did not simply result from 'cancelling out' of individual variations; the rank correlation was also highly significant (P < 0.01 diastolic, P < 0.002 systolic). Remeasurement in the veterinary clinic, rather than 'neutral territory' showed significant increases in pressure but not heart rate. Anticipation of work raised systolic pressure whereas heart rate and diastolic pressure were unchanged. Exposure of a dog to a known stressor for that individual (sound) raised systolic and diastolic pressure as well as heart rate; diastolic pressure was the fastest to recover, heart rate the slowest. The data are compared with other observations on non-invasive blood pressure measurement in both dogs and humans.
使用Dinamap 1846 SX示波监测仪和尾套评估犬动脉压间接测量的可重复性。在20只实验犬中，不同日期的测量结果相关性极佳，收缩压、舒张压和平均动脉压的组均值无显著差异，而心率虽有差异但不显著。均值的相似性并非简单地由个体差异“抵消”所致；等级相关性也非常显著（舒张压P < 0.01，收缩压P < 0.002）。在兽医诊所而非“中性区域”重新测量显示压力显著升高，但心率未变。预期工作会使收缩压升高，而心率和舒张压不变。让犬暴露于该个体已知的应激源（声音）会使收缩压、舒张压和心率升高；舒张压恢复最快，心率恢复最慢。将这些数据与关于犬和人类无创血压测量的其他观察结果进行了比较。
