“…This finding conflicts with the present observations and may be explained by the difficulty encountered by Wishart in determining the systolic pressure in the digits when the peripheral vessels were constricted, or by the fact that Wishart was measuring pressure in vessels distal to the arterioles. Oppenheimer & Prinzmetal [1937] using Gaertner's method found that in normal people digital pressures averaged 29 mm. lower than arm pressures.…”

“…When a subject was warm and the digital vessels dilated, brief reflex digital vasoconstrictions were induced by the application of ice or pin-pricks to an indifferent area, the solving of a mental problem or the taking of a deep breath. It had previously been shown that these stimuli were effective and that the vasoconstriction was the result of impulses in the sympathetic nerves [Sturup, Bolton, Williams & Carmichael, 1935].…”

METHODS The blood pressure has been determined by several methods. Intermittent measurements of arterial pressure were taken in the upper arm and occasionally in the forearm by the ordinary auscultatory method, using a mercury manometer. Intermittent measurements of systolic arterial pressure in the fingers were made by Gaertner's method. This consists of slowly lowering the pressure in a cuff placed around a digit previously rendered bloodless by an elastic band. The pressure in the cuff when the first flush of the returning blood is seen is reckoned as the systolic pressure at the site of the cuff. In several experiments more exact intermittent measurements of systolic arterial pressure were obtained and recorded by a plethysmographic method as follows: A plethysmograph was fitted to a digit and a blood-pressure cuff applied above at the point where it was desired to estimate systolic pressure. Air at greater than systolic pressure was suddenly introduced from a pressure tank into the cuff, occluding the circulation and stopping all pulsations below it. The pressure in mm. Hg within the cuff and the digital volumetric changes were continuously recorded on moving bromide paper by means of an optical system. Pressure was allowed to
