Abstract:

A capsular method for recording evaporation from a small skin area 5, 10, or more sq cm, continuously, quantitatively and with a very fast response time as brief as 0.15 sec is presented. Water of diffusion at rates of 0.005 mgmsq cmmin. or high sweating rates were measured with equal ease. The method is combined with photo electric recording of the skin pulses to provide precise temporal relations of cutaneous vascular events and of sweating in the same segment of skin. less of sweating in forearm skin occurred synchronously with digital vasocon strictions but were not accompanied by changes in the rate of blood flow in forearm skin al though venoconstriction in the forearm often took place with an increase in sweating. The observation contradicted the concept of brady kinin as an important vasodilator in accounting for cutaneous vasodilatation during heat stress.
