Measuring Condition and Indirect Blood Pressure in Non-sedated Dogs by Oscillometric Method

Abstract

The purpose of this study was establishment of conditions to measure blood pressure by a oscillometric method in dogs. For this study, 27 dogs and noninvasive blood pressure taking instrument for animal (BP100D) were used. This study got the following results. There were not significant differences between each blood pressure value measured in a foreleg, a hind leg and a tail. However, as for the time before measured value of blood pressure fell, and being stable, the measurement with a tail was shortest in about 5 minutes. The hair of measurement region did not influence a value of blood pressure. The value of blood pressure in the same animal was not influenced in circadian rhythm by heart rate and rhythm. As for the value of blood pressure in the same animal, it was not influenced by environment of the measurement. However, as for the time before measured value of blood pressure fell, the measurement in an accustomed kennel was shortest in about 5 minutes. These results suggest that the oscillometric method is suitable for measurement of blood pressure in dogs using a tail in the environment where dogs can be relaxed, and we can use values of blood pressure after five minutes from start of the measurement.
