THE MEASUREMENT OF SWAMP BUFFALO (BUBALUS BUBALIS) ARTERIAL BLOOD PRESSURE BY THE STEVEN HALES METHOD

Abstract

Two yearling swamp buffalo (Bubalus bubalis) calves, one male and one female, were used for
measuring their carotid blood pressure by the classic Stephen Hales method. The animals were premedicated with xylazine hydrochloride followed by intravenous guaifenesin-thiopental. The systolic blood pressure in the male calf was 145.7 mmHg, while the Statham transducer showed 150 mmHg. The pressure in the female calf was 136.2 mmHg and 140 mmHg by the Stephen Hales and electronic methods, respectively.
