The present study compared 2 indirect methods, Doppler sphygmomanometry and oscillometry, for measurement of the systemic blood pressure level in 100 conscious, client-owned dogs in a clinical setting on 2 separate occasions. The mean systemic blood pressure values, measured by Doppler sphygmomanometry on 2 separate occasions, were 156 +/- 38.2 mmHg and 150 +/- 34.1 mmHg, respectively. Using oscillometry, the mean systolic blood pressure values were 138 +/- 36.9 mm Hg and 133 +/- 33.5 mm Hg on 2 separate occasions. There were significant differences between the systemic blood pressure readings for both methods on the same occasion (P<0.001). The coefficients of variance from 5 consecutive measurements in the same dog obtained by Doppler sphygmomanometry on the 2 separate occasions were 4.1 +/- 3.2% and 3.1 +/- 1.7%; that of the oscillometric method on the 2 separate occasions were 18.7 +/- 11.3% and 17.2 +/- 12.5%. The coefficients of variance of these 2 methods were statistically different on each occasion (P<0.001). Five consecutive systemic blood pressure readings were obtained for each dog within 6 min on both occasions using Doppler sphygmomanometry. More than 15 min was required to complete 5 consecutive systemic blood pressure readings by oscillometric sphygmomanometry for all dogs on each occasion. The results of this study indicate that Doppler sphygmomanometry provides more efficient and precise measurements of the systemic blood pressure level than oscillometric testing in conscious dogs in a clinical setting.
本研究在临床环境中，于两个不同时间点，对100只意识清醒、客户拥有的犬只，比较了两种间接测量方法，即多普勒血压计法和示波法，以测量其全身血压水平。通过多普勒血压计法在两个不同时间点测得的平均全身血压值分别为156±38.2 mmHg和150±34.1 mmHg。使用示波法时，在两个不同时间点测得的平均收缩压值分别为138±36.9 mmHg和133±33.5 mmHg。在同一时间点，两种方法测得的全身血压读数存在显著差异（P<0.001）。通过多普勒血压计法在两个不同时间点对同一只犬连续进行5次测量所得的变异系数分别为4.1±3.2%和3.1±1.7%；示波法在两个不同时间点的变异系数分别为18.7±11.3%和17.2±12.5%。这两种方法在每次测量时的变异系数在统计学上均有差异（P<0.001）。使用多普勒血压计法，在两个时间点均于6分钟内为每只犬连续获取5次全身血压读数。每次使用示波血压计法为所有犬连续获取5次全身血压读数均需要超过15分钟。本研究结果表明，在临床环境中，对于意识清醒的犬只，多普勒血压计法比示波法能更高效、精确地测量全身血压水平。
