Abstract:
The temperatures of the tip of the middle fingers Ts of nine comfortably warm subjects have been recorded during immersion of all the fingers of one hand in a 27 liter bath containing slowly stirred water at temperatures ranging from 4.6 to 40C Tw. Blood flow F mlsq cmmin was estimated from the average Ts for the last 15 minutes of a 20-minute period, Tw and body temperature Tb by using the equation F 1087 x KTs - TwTb - Ts. K 0.0134 kcalsq. cmminC. The increase in F per C reduction in Tw below 10C was 0.16 0.077 P.05. This value gives a measure of the vasodilatation occasioned by immersion in water below 10C. The sample regression equation of F on Tw was F 4.1 -.16 Tw 0.17 n 27 range of Tw 4.6 to 10C. This method of estimating blood flow at several levels of Tw describes more fully the peripheral circulatory response to cold than methods in which only one level of Tw is used. Author
