Abstract:

Calorimetric estimates of cutaneous blood flows in the finger pads, calf and forearm were compared with simultaneous photometric recordings of the skin pulses by photoelectric plethysmographs in these same areas. The amplitude of the skin pulse, expressed as percent decrement in photoelectric current, was related linearly to the blood flow, during cutaneous vasodilatation elicited by body heating and by the local application of a vasodilator drug. Cutaneous blood flow in any skin region of the normal resting subject may be estimated from the relation, blood flow in cc. per sq. cm. per min0.2A, where A is the amplitude of the skin pulse expressed as percent decrement in photoelectric current.
