Arterial blood pressure values in anesthetized horses were determined by one direct and two indirect methods and compared to control values obtained simultaneously by direct measurement with a strain gauge. Results of all three techniques differed significantly from control arterial pressure; the values obtained using an aneroid manometer and electronic sphygmomanometer were slightly less than control pressure, and values obtained by auscultation were greater than control. The direct method with the aneroid manometer was most acceptable because of its accuracy, ease of operation, adaptability, and cost. The electronic sphygmomanometer was also acceptable because of its accuracy and ease of operation. The auscultation technique was not as accurate as the other methods but can be used clinically if its limitations are considered.
