Abstract:
1. A method of compensating for temperature error in a pneumatic pumping system of a peritoneal dialysis system, the peritoneal dialysis system including a pumping mechanism with a disposable cassette and at least one disposable chamber, wherein fluid communication is established between the peritoneal dialysis system and a peritoneal cavity of a patient, the method comprising: (i) calculating a corrected volume of air in a disposable chamber, wherein V (ii) multiplying the result of (i) by a ratio of a temperature in the disposable chamber to a temperature in the reference chamber T (iii) multiplying the result of (ii) by a ratio of Tr (iv) calculating a corrected volume of air delivered by the disposable chamber of the system by applying the correction factor; and (v) correcting a volume of dialysate pumped by the dialysis system using the corrected volume of air.
