The oscillometer is an instrument which measures in arbitrary units the amount of pulsation transmitted to a pneumatic cuff applied to a segment of an extremity. An excellent discussion of the history of oscillometry and of the nature and use of the available instruments, with bibliography, has been given by Samuels.1
Oscillometry has been advocated as a simple means of detecting decreases in arterial pulsation in peripheral arteriosclerotic disease. However, practical application of the science for this purpose by my associates and me proved disappointing, because the results obtained were often confusing. There is normally considerable variation in oscillometric readings recorded at the same level of an extremity in different persons. Thus at the supramalleolar level (the region just proximal to the ankle joint, corresponding approximately to the distal fourth of the leg), readings between 1 and 10 comprise the "normal" range. We, as will be shown, have recorded
