Plasmapheresis is a medical procedure that involves separating blood plasma from blood cells. During the process, a patient's blood is drawn out and passed through a special machine called a separator. This machine spins the blood at high speeds, separating it into plasma and blood cells. The plasma, which contains various components like antibodies, proteins, and waste products, is then either discarded, treated, or replaced with a substitute. The remaining blood cells are returned to the patient, often mixed with the substitute plasma.

This procedure is used to treat a range of medical conditions, particularly those involving the immune system. It is employed when the plasma contains harmful substances that are contributing to a disease. For example, plasmapheresis can be used in autoimmune disorders where the body's immune system mistakenly attacks its own tissues. By removing the problematic plasma, the severity of the disease can be reduced. It is also utilized in cases of certain poisonings or to remove excess cholesterol from the blood.

The procedure itself is generally safe, but like any medical intervention, it carries potential risks and side effects. These can include temporary drops in blood pressure, bruising at the needle insertion site, or reactions to the anticoagulant used to prevent blood clotting. The decision to undergo plasmapheresis is made by a medical professional based on the patient's specific condition and medical history. The frequency and duration of the treatment are tailored to individual needs.
