Systemic Vascular Resistance in Intradialytic Hypotension Determined by Means of Impedance Cardiography

Abstract

Intradialytic hypotension seems the consequence of an inadequate compensatory response to ultrafiltration-induced blood volume reduction, resulting in a fall in systemic vascular resistance. The degree of hypovolemia itself appears to be less important in the origin of acute, intradialytic hypotensive episodes. Noninvasive monitoring during hemodialysis provides an opportunity to gain more insight into the pathophysiology of intradialytic hypotension and offers the possibility for controlled intervention and possible prevention of this complication.
