Measurement of Mean Arteria Pressure in Rats by a Tail-cuff Method with Sensitive Photoelectric Sensors

Evaluation of a New Tail-cuff Method for Blood Pressure Measurement in Rats with Special Reference to the Effects of Ambient Temperature

“…To measure arterial blood pressure in rats, many laboratories have used indirect [ 1,2,9,10,12] and direct methods [4,11] . The indirect method uses a tail-cuff to measure only systolic blood pressure and usually this method requires external heating to obtain a large pulse volume [11. Because rats use their tails to regulate body temperature, their tail vessels dilate at high ambient temperatures.…”
