Abstract:
1. A method of modeling a patient's peritoneal dialysis drain phase comprising: determining a constant flowrate for the patient residing in a particular patient position; modeling a first segment of a drain phase curve as having the constant flowrate; modeling a second segment of a drain phase curve as having a decaying exponential flowrate; incorporating a switching component into the first and second segments so that (i) at a first time the first segment is active while the second segment is inactive and (ii) at a second time the first segment is inactive while the second segment is active; and programming a computer to use the modeled first and second drain phase segments for at least one of: (i) determining a drain time for an automated peritoneal dialysis (“APD”) machine, (ii) determining a dwell time for the APD machine, (iii) determining a drain time for a continuous ambulatory peritoneal dialysis therapy, (iv) setting a low flowrate alarm in the APD machine, (v) setting a minimum drain volume percentage in the APD machine, (vi) determining a dwell time for use in kinetically modeling a patient, and (vii) preventing overfilling of the patient.
