heart-lung machine

 
a mechanical device that temporarily takes over the functions of the heart and lungs; it is used as an aid in some surgeries, especially cardiovascular surgery. The “heart” of the machine is a pump that draws blood from the patient's vessels before it reaches the heart. The blood is routed through a “lung” chamber (usually made of plastic), where it receives oxygen. The oxygenated blood is then returned to the patient's vessels and pumped through the circulatory system. (This method of circulating the blood outside the patient's body is known as extracorporeal circulation.) Called also pump oxygenator.

heart-·lung ma·chine

a device incorporating a blood pump (artificial heart) and a blood oxygenator (artificial lung) to provide extracorporeal circulation and oxygenation of the blood during cardiac surgery.

heart-lung machine

(härt′lŭng′)
n.
An apparatus through which blood is diverted in order to oxygenate it and pump it throughout the body, used especially during heart surgery to maintain circulation until normal heart and lung function are restored.

heart-lung machine

an apparatus consisting of a pump and an oxygenator that takes over the functions of the heart and lungs, especially during open heart surgery. The blood is shunted from the venous system through an oxygenator and returned to the arterial circulation.

Extracorporeal circulation, pump-oxygenator Heart surgery A device with a pump and a blood oxygenator, used during open heart–eg, cardiothoracic and cardiovascular surgery; the HLM does the work of the heart–pump blood and lungs–oxygenating the blood, by routing the blood through the machine before returning it to the arterial circulation

HEART-LUNG MACHINE
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. See: illustration

heart-lung machine

A bulky device that is able to carry out the functions of the heart and the lungs, during the period of a surgical operation on the heart. The machine includes atraumatic rotary pumps powerful enough to maintain the circulation through the body, blood filters for particles, bubbles and foam, a blood oxygenator and carbon dioxide extractor, a cooler and a re-heater. Blood from the patient's main veins is carried in tubes to the machine and the machine output is connected to the main body artery (the aorta). ANTICOAGULANTS are used to prevent blood clotting.
