A device that oxygenates and circulates blood in the body during a coronary bypass or other appropriate surgical procedure.
A machine used to pump blood round the body and maintain the supply of oxygen to the blood during heart surgery.
Mechanical device that serves as artificial lungs and heart during some cardiac procedures.
A device that takes over the functions of the heart and lungs during open-heart surgery. The heart-lung machine consists of a pump, which circulates the blood and substitutes for the heart, and an oxygenator, which, taking over for the lungs, removes carbon dioxide from the blood and adds oxygen. Because the heart-lung machine is keeping the person undergoing open heart surgery alive, the surgeon can stop the heart to work on it without causing bleeding.
An apparatus for taking over temporarily the functions of both the heart and the lungs during heart surgery. It incorporates a pump, to maintain the circulation, and equipment to oxygenate the blood. Blood is taken from the body by tubes inserted into the superior and inferior vena cava, and the oxygenated blood is returned under pressure into a large artery, such as the femoral artery. The surgeon is therefore able to undertake the repair or replacement of heart valves or perform other surgical operations involving the heart and great blood vessels.
A machine through which a patient’s blood is circulated, bypassing the patient’s heart, during surgery on the heart. The machine supplies the heart’s pumping function during the operation, and also acts as a lung, supplying oxygen to the blood.
A device that temporarily takes over the function of the heart and lungs. It is used in certain operations in the chest, giving the surgeon more time for procedures such as open-heart surgery, heart transplants and heart-lung transplants. The machine also ensures an operating area largely free of blood, which helps the surgeon to work more quickly. A pump replaces the heart and an oxygenator replaces the lungs. When working, the machine in effect bypasses normal cardiopulmonary activity. It also contains a heat exchanger to warm or cool the patient’s blood according to the requirements of the operation. The patient is given an anticoagulant (heparin) to counteract clotting which may occur when blood cells get damaged during the machine’s use. Patients are attached to the machine for a few hours only, because blood supply to vital organs begins to be reduced.
A device that maintains the functions of the heart and lungs while either or both are unable to continue to function adequately. The device pumps, oxygenates, and removes carbon dioxide from the blood. In animal studies and in open heart surgery, these machines take over the function of the heart and lungs while these organs are being treated or possibly replaced. The function of the heart-lung machine is also called heart-lung bypass.
A medical device designed to temporarily assume the roles of the heart and lungs, enabling procedures like open heart surgery, heart transplant, and heart-lung transplant.
The heart-lung machine comprises a pump to mimic the heart’s function and an oxygenator to replicate the lungs’ function. By bypassing the heart and lungs, the machine allows the patient’s heart to be temporarily stopped during surgery while maintaining vital oxygenation and circulation.
The utilization of a heart-lung machine can lead to damage to red blood cells and blood clotting. Nonetheless, these issues can be mitigated by administering heparin, an anticoagulant drug.
A heart-lung transplant is a surgical procedure where the patient’s heart and lungs are replaced with donor organs. It is employed to treat conditions where either lung damage has affected the heart or vice versa, such as cystic fibrosis, fibrosing alveolitis, and certain severe congenital heart defects. During the operation, a heart-lung machine is utilized to temporarily take over the functions of the patient’s heart and lungs. In comparison to a heart transplant, a heart-lung transplant is not more dangerous and is technically simpler since there is no need to disturb blood vessels connected to the lungs.
