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.
Claims20
A method for monitoring intraperitoneal volume (IPV) of a fluid during a dwell period of a peritoneal dialysis treatment, the method comprising:
- monitoring intraperitoneal pressure (IPP) of the fluid during the dwell period using a pressure sensor;
- measuring a volume and a weight of at least one sample of the fluid during the dwell period;
- determining a density of the fluid during the dwell period based on the volume and the weight of the at least one sample;
- and
- determining IPV based at least on a change in IPP and a change in the density during the dwell period.
One or more non-transitory computer-readable media storing instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:
- determining an intraperitoneal pressure (IPP) of a fluid during the dwell period using a pressure sensor;
- determining a change in the intraperitoneal volume (IPV) based at least on a change in the IPP of the fluid during the dwell period;
- determining a density of the fluid during the dwell period based on a volume and a weight of at least one sample of the fluid;
- and
- determining an IPV of the fluid based at least on a change in the IPP and a change in the density during the dwell period.
