Abstract
Techniques for monitoring intraperitoneal volume (IPV) during a dwell period of a peritoneal dialysis patient include monitoring intraperitoneal pressure (IPP) during the dwell period using a pressure sensor, monitoring the density of the dialysate during the dwell period, and determining a change in IPV based at least on a change in IPP and a change in the density of the dialysate during the dwell period.
