title: Investigation of the venous hemodynamics of the lower limb by venous pressure models.
abstract: The conversion of the measured ambulatory venous pressure (AVP) to a value resulting from a resting venous pressure of 100 mmHg is significant for a standardized evaluation of the venous dynamics in different patients. By applying the formulas derived from the measured ambulatory and resting venous pressures, the venous insufficiency and the functional reserves can be calculated in percent. By combining the refilling time (RT) with the venous pressure index (VPI), the venous pressure hemodynamic index (VPHI) results, which is a very sensitive parameter also for minimal changes in the venous hemodynamic. Thus, the venous dynamics can be compared before and after a treatment in the same or in different persons.
