On Auto-regulation Factor (ARF) of Circulation System and Dialysis-induced Hypotension

Abstract

An auto-regulation factor (ARF) of the circulation system is proposed for predicting the cardiac shock during the hemodialysis. ARF summarises the controllability of maintaining the cardiac output and mean arterial pressure. ARF reflects the increment of HR and TPR against the decrement of blood volume and cardiac output. ARF can be counted only from the systolic and diastolic pressure and HR. ARF changes more widely from the early stage of dialysis than mean arteril pressure itself.
We could find the possibility of using the ARF as the index for predicting the occurance of the dialysis-induced bypotention.
