A MAQUET hollow fiber membrane oxygenator. A membrane oxygenator is a device used to add oxygen to, and remove carbon dioxide from the blood.It can be used in two principal modes: to imitate the function of the lungs in cardiopulmonary bypass (CPB), and to oxygenate blood in longer term life support, termed extracorporeal membrane oxygenation (ECMO).
This work helped lead to extracorporeal membrane oxygenation , when a machine replaces the heart and lung for long periods of time. Theodor Kolobow (1931 – 24 March 2018) [1] [2] was an American physician, scientist, physiologist, and inventor of medical devices, including the membrane oxygenator, common to most modern heart-lung machines.
The device used is a membrane oxygenator, also known as an artificial lung. ECMO works by temporarily drawing blood from the body to allow artificial oxygenation of the red blood cells and removal of carbon dioxide. Generally, it is used either post-cardiopulmonary bypass or in late-stage treatment of a person with profound heart and/or lung ...
The heart-lung machine inspired the design of AL devices, however, modern ALs are optimised to minimize patient trauma. Following the development of the heart-lung machine, Extracorporeal Membrane Oxygenation , using a membrane oxygenator, was developed. This was intended to be used as a bridge to lung transplant (BTT), for patients too sick to ...
Bubble oxygenators have no intervening barrier between blood and oxygen, these are called 'direct contact' oxygenators. Membrane oxygenators introduce a gas-permeable membrane between blood and oxygen that decreases the blood trauma of direct-contact oxygenators. Much work since the 1960s focused on overcoming the gas exchange handicap of the ...
One component of the heart-lung machine is the oxygenator. The oxygenator component serves as the lung, and is designed to expose the blood to oxygen and remove carbon dioxide. It is disposable and contains about 2–4 m² of a membrane permeable to gas but impermeable to blood, in the form of hollow fibers. [2]

The liquid ventilator removes Carbon dioxide (CO 2) from the PFC by saturating it with oxygen (O 2) and medical air. This procedure can be performed with either a membrane oxygenator (a technology used in extracorporeal oxygenators) or a bubble oxygenator. [13] The liquid ventilator heats the PFC to body temperature.
