Tail-cuff blood pressure measurement without external preheating in awake rats.
A new photoelectric sensor capable of detecting tail pulses even in unheated rats was tested for accuracy in indirect measurements of blood pressure. This sensor proved more sensitive than a Doppler ultrasonic flowmeter because it allowed detection not only of tail pulsations without preheating but also of peak oscillations usable for estimating mean arterial pressure. After blood pressures in ...
متن کاملAn impedance method for blood pressure measurement in awake rats without preheating.
The tail-cuff methods for measuring systolic blood pressure in the rat usually require preheating of the animal to obtain recordable pulse signals. To find a more sensitive method, we applied the principle of differentiated impedance (dZ/dt) to the tail-cuff measurement of systolic blood pressure. We obtained clear pulse signals from the tail in awake rats without preheating the animals, and th...
متن کاملValidation in awake rats of a tail-cuff method for measuring systolic pressure.
Bu~~AG, RUBEN D. Validation in awake rats of a tail-cuf method for measuring systolic pressure. J. Appl. Physiol. 34(2) : 279-282. 1973. -To determine why results of recent studies on applicability of the tail-cuff method to awake rats have been conflicting, arterial pressures were measured under various conditions. A Doppler ultrasonic flowmeter was used to detect blood flow changes occurring ...
متن کاملValidation of volume-pressure recording tail-cuff blood pressure measurements.
BACKGROUND The American Heart Association has recommended tail-cuff blood pressure measurement for high-throughput experimental designs, including mutagenesis screens and genetic crosses. However, some tail-cuff methods show good agreement with radiotelemetry and others do not, indicating that each tail-cuff method requires independent validation. METHODS We validated the volume-pressure reco...
متن کاملA simple versatile method for measuring tail cuff systolic blood pressure in conscious rats.
1. The non-invasive measurement of tail cuff systolic blood pressure in conscious rats is routinely used in long-term cardiovascular studies. There are a number of commercially available tail cuff systems, however, these apparatus are generally expensive and are dedicated for single-task operations. In the present study, a simple method for measuring systolic blood pressure, which requires only...
