Abstract
Peritoneal dialysis systems apply fluid pressure to move liquid. The systems can emulate either a fixed head height condition or different head height conditions, independent of the actual head height differential between the patient's peritoneal cavity and the external liquid source or destination. The systems can also switch between low-relative pressure flow mode when considerations of patient comfort and safety predominate and a high-relative pressure flow mode when considerations of processing speed predominate.
