Method of increasing flow rates in pneumatic based apd systems without risk of pushing air into the patient

Abstract

An example automated peritoneal dialysis (“APD”) system may include a disposable cassette in fluid communication with a patient line for delivering a dialysis fluid to and from a patient and a cycler comprising at least one pneumatic dialysis fluid pump configured to interact with the disposable cassette to pump the dialysis fluid to and from the patient. The system may further include a sensor located along the patient line configured to output one or more readings indicative of air bubbles in the patient line and a control unit programmed to operate the at least one pneumatic dialysis fluid pump to deliver the dialysis fluid to the patient at a flow rate between 350 ml/min to 450 ml/min. The control unit may be further configured to receive the one or more readings from the sensor and determine an amount of air in the patient line.
