A perfusionist in front of a heart–lung machine (upper right) early in a coronary artery bypass surgery. A cardiovascular perfusionist, clinical perfusionist or perfusiologist, and occasionally a cardiopulmonary bypass doctor [1] [2] or clinical perfusion scientist, [3] is a healthcare professional who operates the cardiopulmonary bypass machine (heart–lung machine) during cardiac surgery ...
In 1920, August Krogh was awarded the Nobel Prize in Physiology or Medicine for his discovering the mechanism of regulation of capillaries in skeletal muscle. [6] [7] Krogh was the first to describe the adaptation of blood perfusion in muscle and other organs according to demands through the opening and closing of arterioles and capillaries.
Cardiopulmonary bypass (CPB) or heart-lung machine, also called the pump or CPB pump, is a machine that temporarily takes over the function of the heart and lungs during open-heart surgery by maintaining the circulation of blood and oxygen throughout the body. [1]
The perfusionist uses gravity to drain the venous blood into the CPB machine, and a separate cannula, usually placed in the aorta or femoral artery, is used to return blood to the arterial circulation. The process of preparation, initiation, and separation of cardiopulmonary bypass is a critical time during cardiac surgery.
Perfusion is a multidisciplinary journal that provides current information on all aspects of perfusion, oxygenation and biocompatibility and their use in modern cardiac surgery.
Ex-vivo lung perfusion conduct on a rat. Ex vivo lung perfusion, EVLP, is a form of machine perfusion aimed at sustaining the active aerobic cellular metabolism of donor lungs outside the donor's body prior to lung transplantation.
Intraoperative blood salvage (IOS), also known as cell salvage, is a specific type of autologous blood transfusion. Specifically IOS is a medical procedure involving recovering blood lost during surgery and re-infusing it into the patient.
Perfusion is the passage of fluid through the lymphatic system or blood vessels to an organ or a tissue. [1] The practice of perfusion scanning is the process by which this perfusion can be observed, recorded and quantified.
