Acoustic Analyses of the Digital Doppler Allen Test.

ABSTRACT:

Background

In this study, we aimed to perform noninvasive acoustic quantification of digital arterial Doppler sounds and to determine the possibility of evaluating digital arterial circulation using the results of acoustic assessment.

Methods

In this prospective study, we recorded the Doppler sounds of the radial and ulnar digital arteries of all digits of 25 volunteers (male, n = 10; female, n = 15) included in the study, converted these recordings into digital files, and analyzed them using a fast Fourier transform analyzer. We recorded the Doppler sound of each digital artery by means of (1) contralateral digital artery compression, (2) ipsilateral digital artery compression, and (3) no compression as a control. The analyzed parameters comprised the equivalent sound level
