A process of removing chemical substances and water from the blood by passing it through an artificial kidney composed of semi-permeable membranes.

Protein found in erthrocytes that transports oxygen in the blood.

The destruction of red blood cells resulting in the liberation of haemoglobin, potassium and other cell contents.

Abnormal bleeding, either internal or external.

A powerful anticoagulant that blocks/suppresses clotting of the blood. In peritoneal dialysis heparin can be added to the dialysis solution. Heparin inhibits the formation of fibrin and may prevent subsequent adhesion formation.

Abnormally increased volume of circulating blood in the body.

Not enough potassium in the blood.

Decreased blood flow through an organ, as in circulatory shock. If prolonged, it may result in permanent cellular dysfunction and death.

Low blood pressure.

Abnormally low body temperature.
