The relation between finger blood flow level and the periodicity in slower finger volume fluctuations was studied in humans by using mercury plethysmography. The periodicity was analysed by means of autocorrelographic and harmonic analysis. Slower periodic waves, not originating in the heart beat or the respiratory cycle, were found throughout the range of finger blood flow above 10 ml/min 100 ml tissue, but not below this blood flow level. The period of the shortest volume wave, except the pulse and respiratory waves, prolonged with increased finger blood flow.
