Analysis of Vacuous Pulse and Replete Pulse by Using a Clip-type Pulsimeter Equipped with a Hall Sensor

A logistic regression equation for the vacuous pulse and the replete pulse was determined based on data obtained by using a clip-type pulsimeter equipped with a Hall device that sensed the change in the magnetic field due to the minute movement of a radial artery. To evaluate the efficacy of the two different pulses from the deficiency and the excess syndrome groups, we performed a clinical trial, and we used a statistical regression anaylsis to process the clinical data from the 180 subjects who were enrolled in this study. The ratio of the systolic peak’s amplitude to its time in the pulse’s waveform was found to be a major efficacy parameter for differentiating between the vacuous pulse and the replete pulse by using an empirical equation that was deduced from the data by using a statistical logistic regression method. This logistic regression equation can be applied to develop a novel algorithm for pulse measurements based on Oriental medical diagnoses.
