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] As such it is an extracorporeal device. CPB is operated by a perfusionist. The ...
Generally, it is used either post-cardiopulmonary bypass or in late-stage treatment of a person with profound heart and/or lung failure, although it is now seeing use as a treatment for cardiac arrest in certain centers, allowing treatment of the underlying cause of arrest while circulation and oxygenation are supported.
Cardiopulmonary bypass (CPB) is a medical technique to oxygenate the blood and remove the carbon dioxide during the cardiac operation. [4] It can be seen as a “pump” to serve as a heart-lung machine whose function is sustaining blood circulatory and transporting oxygen to red blood cells before blood is flowing backwards the arterial ...
Postperfusion syndrome, also known as "pumphead", is a constellation of neurocognitive impairments attributed to cardiopulmonary bypass (CPB) during cardiac surgery. Symptoms of postperfusion syndrome are subtle and include defects associated with attention, concentration, short-term memory, fine motor function, and speed of mental and motor ...
Catheterization and establishment of cardiopulmonary bypass After harvesting, the pericardium —the sac that surrounds the heart—is opened and stay sutures are placed to keep it open. Purse string sutures are placed in the aorta to prepare the insertions of the cannula into the aorta, and a catheter which temporarily arrests the heart using ...
By cooling blood directly, cardiopulmonary bypass also cools people faster than surface cooling, even if the heart is not functioning. In 1959, using cardiopulmonary bypass (CPB), Barnes Woodhall and colleagues at Duke Medical Center performed the first brain surgery using DHCA, a tumor resection, at a brain temperature of 11 °C and esophageal ...
Richard A. DeWall (1926–2016), was an American cardiothoracic surgeon who in 1955 created the first workable, portable bubble oxygenator that removed bubbles, thus avoiding gas embolism during cardiopulmonary bypass. Later, he wrote the original plans for what became the Wright State University School of Medicine.
Impella was approved for mechanical circulatory support in 2008, but large-scale, real-world data on its use are lacking. In June 2008, the Impella 2.5 heart pump received FDA 510(k) clearance [22] for partial circulatory support for periods of up to six hours during cardiac procedures not requiring cardiopulmonary bypass.
