Patent ID: 8444593

Claim:
A peritoneal function testing method using a Three-Pore Theory model, the method being executed by a peritoneal dialysis planning apparatus that includes an input unit, a computing unit, an output unit, and a storage unit, the method comprising: an obtaining step of obtaining data from a dialysis patient using the input unit; a storing step of storing the data obtained from the dialysis patient in the storage unit; a first calculating step, in which the computing unit calculates, based on data that is obtained from a dialysis patient and stored in the storage unit, a permeability coefficient for cell pores (L P S C ) and an overall permeability coefficient (L P S); a second calculating step, in which the computing unit calculates a ratio L P S C /L P S using the L P S C and the L P S; a generating step, in which the computing unit generates a graph presenting a correlation between the L P S C /L P S ratio and a volume of water removal; and a outputting step in which the output unit outputs, to a display, the graph presenting the correlation between the L P S C /L P S ratio and the volume of water removal as an index for a peritoneal function test, wherein the index for the peritoneal function test is used for determining if adjustments in a peritoneal dialysis treatment of the dialysis patient are needed.
