1. A method to test the integrity of a membrane of a dialyzer in a hemodialysis system with each therapy, the method comprising:
pumping a liquid from a dialysate path through the dialyzer into a blood path;
stopping the pumping of the liquid into the blood path;
pumping air into the blood path;
displacing the liquid in the blood path through the membrane of the dialyzer with the air;
monitoring a flow of the air in the blood path; and
detecting a ruptured membrane of the dialyzer when the flow of the air does not stop once the liquid in a blood path side of the dialyzer has been displaced by the air.
