A study of weight-loss control during hemodialysis by employing regression estimates

Abstract

It has been difficult to obtain an effective means of manual control of ultrafiltration, even though there are many patients in whom rate of weight loss for a given transmembrane pressure gradient (TMPG) is difficult to predict. The present study was undertaken to obtain an optimal TMPG by using mathematical methods.
The results indicated that (TMPG X duration of dialysis) correlated well with the weight loss observed during dialysis. The weight loss estimated by applying the regression line consistently agreed with that actually observed in the patients.
