OsciPulse D-dimer Pilot Trial

This is a single site, randomized open label two arm study. The patient population will be randomly divided into two arms, with one receiving the OsciPulse System and the other receiving standard intermittent compression therapy. Both arms will have the therapy applied within 24 hours of admission and continue during their hospital stay until day 7 or discharge, whichever is shorter, unless clinically required to be removed. Daily d-dimer levels will be assessed until day 7 or discharge. If required beyond day 7, standard compression therapy will be provided. An interim analysis will be performed after 20 subjects are enrolled to evaluate the speed of enrollment and data variability and quality. If indicated, enrollment will be increased up to 40.
