Aquapheresis is a procedure to remove excess salt and water from patients with fluid overload or congestive heart failure.

During aquapheresis, patients are hooked to a machine, which is similar to an IV pump. The machine acts as a filtration system, drawing out the patient's blood, separating it from the excess salt and water, and then returning the "clean" blood back to the patient's body. The excess fluid is collected in a bag for disposal. Depending on your condition, you might start to feel better right away or it may take some time.

Studies show that patients treated with aquapheresis over standard IV medicines see a 38 percent weight loss, a 50 percent reduction in re-hospitalization, a 63 percent reduction in total re-hospitalization days and a 52 percent reduction in emergency department or clinic visits.
