The precision and accuracy of an indirect oscillometric blood pressure measurement technique (Dinamap 8100) was assessed in 11 anesthetized Beagle dogs weighing 8 to 11.5 kg. Direct blood pressure measurements were made by catheterization of the lingual artery, and simultaneous indirect measurements were determined by placing a cuff over the median artery (midradial area). Blood pressure measurements at 2 different planes of anesthesia (light and deep) were recorded in triplicate. At a light plane of anesthesia, the Dinamap 8100 underestimated diastolic and mean arterial pressure, and at a deep anesthetic plane overestimated systolic pressure. The indirect technique had good repeatability of systolic pressures. Regression analysis for the 2 techniques showed excellent correlation (r = 0.93). The results indicate that the indirect oscillometric blood pressure measurement technique provides a good estimate of systolic, diastolic, and mean arterial pressure in dogs weighing 8-11.5 kg.
在11只体重8至11.5千克的麻醉比格犬中评估了一种间接示波血压测量技术（Dinamap 8100）的精密度和准确性。通过舌动脉插管进行直接血压测量，并通过在正中动脉（桡骨中部区域）放置袖带进行同步间接测量。在麻醉的2个不同平面（浅麻醉和深麻醉）下的血压测量记录3次。在浅麻醉平面下，Dinamap 8100低估了舒张压和平均动脉压，而在深麻醉平面下高估了收缩压。间接技术的收缩压具有良好的重复性。两种技术的回归分析显示出极好的相关性（r = 0.93）。结果表明，间接示波血压测量技术能很好地估计体重8 - 11.5千克犬的收缩压、舒张压和平均动脉压。
