Patent ID: 8180574

Claim:
A system for performing a simplified peritoneal equilibration test, the system comprising: a computer; and a non-transitory computer-readable medium accessible to the computer and containing a software program therein, wherein the software program is programmed to cause a computer processor to accept inputs concerning at least two concentrations of a substance in samples of a dialysis fluid from at least two separate times after a start of a dialysis therapy of a patient, wherein the software program includes a formula ( CD t −CD eq )=( CD 0 −CD eq ) e −(t/τ) , where CD t is a concentration of the substance in the dialysis fluid at time t, CD eq is an equilibrium concentration of the substance, CD 0 is an initial concentration of the substance in the dialysis fluid, t is the time and τ is an equilibration time constant of a transport property of a peritoneum of the patient for the substance, wherein the software program is programmed to cause the computer processor to use the formula to calculate the CD eq of the substance wherein the CD eq is approximately equal to an equilibrium concentration of the substance in the blood of the patient, and wherein the software program is further programmed to cause the computer processor to suggest at least one transport property of the peritoneum of the patient.
