The heart-lung machine provides the benefit of a motionless heart in an almost bloodless surgical field. Cardioplegia solution is delivered to the heart resulting in cardiac arrest heart stoppage.

Pumping and oxygenating blood.
Heart and lungs machine. Blood returning to the heart is diverted through a heart-lung machine before being returned to arterial circulation. For most patients needing heart valve surgery a heart-lung machine is typically used during the operation. It is a means of keeping a patient alive while hisher heart is stopped or even removed from the body.
Heart-Lung Machines Bypass A heart-lung machine Figure 89-10 is an apparatus that does the work both of the heart ie pumps blood and the lungs ie oxygenates the blood during for example open-heart surgery Galletti and Colton 1995. A heart lung machine is a piece of medical equipment which is designed to take over the function of the heart and lungs during surgery so that a surgeon can operate in a relatively bloodless field on a heart which is not moving. As you may know the heart-lung machine enables the surgeon to stop and cool the heart so the valve can be fixed while the heart is not beating.
Then the heart-lung bypass machine is connected to your heart. 32 Oxygenator performs the same function as the lungs It is filtered cooled oxygenated and pumped back via a second cannula in the aorta or femoral artery A third tube near or in the heart flushes it with potassium solution to stop the heart cardioplegia.

The Century Heart Lung Machine offers exceptional value in a sturdy easy-to-use modular system with features important to perfusionists. Operating on a beating heart is extremely difficult and the heart-lung machine allows blood to bypass the heart while surgeons work. Patients suffering from acute cardiomyopathy are kept alive using a special life support system known as the heart-lung machine.
The machine uses gravity to. By using CPB a surgeon can operate on a heart that has been arrested and is not full of blood. The heart-lung machine is a device that is connected to the blood vessels and serves as the persons heart and lungs for a period of time.
The oxygenator removes cardiovascular disease. The heart-lung machine HLM is a device used to provide blood circulation and oxygenation while the heart is stopped. A machine that does the work both of the heart and of the lungs.
Also known as pump-oxygenator or cardiopulmonary bypass machine. The cardiopulmonary bypass pump or heart-lung machine as it is commonly known can take on the role of the heart and lungs during cardiac surgery. During open heart surgery the heart lung machine HLM also known as a cardiopulmonary bypass CPB machine diverts the blood away from the heart and lungs into a machine that takes over the pumping and ventilatory functions of these organs.
The heart-lung machine is invaluable during this time since the patient is unable to maintain blood flow to the lungs or the body. Using this machine ensures that it takes over the circulatory functions of the patients heart. Such machines may be used during open-heart surgery.
The heart-lung machine is a mechanical pump that maintains a patients blood circulation and oxygenation during heart surgery by diverting blood from the venous system directing it through tubing into an artificial lung oxygenator and returning it to the body. In other words the patients blood bypasses the heart to enter the machine instead where it is oxygenated just as it would be in the lungs. The machine takes over the hearts pumping action as it moves blood away from the heart and a specialist oversees the machine throughout the procedure.
The pump allows the surgeon to operate on a heart that isnt beating and that doesnt have blood flowing through it. This electronic device is also known as the cardiopulmonary bypass machine. A Quick History of the Heart-Lung Machine.
