Claim:
1. A method of returning blood in a patient tubing set of a dialysis delivery system to a patient after a dialysis treatment, comprising: creating a pathway between a saline source and the patient tubing set at a patient arterial access site; activating a blood pump in a forward direction, the blood pump being coupled to the patient tubing set, to draw saline from the saline source into the patient tubing set at the patient arterial access site and push blood back into the patient; tracking a number of revolutions of the blood pump to determine a volume of saline drawn into the patient tubing set; and de-activating the blood pump when a predetermined volume of saline is drawn into the patient tubing set, wherein the predetermined volume of saline is integrated into a fluid removal target for ultrafiltration during the dialysis treatment so a target weight of the patient is attained after returning the blood in the tubing set to the patient.
