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).
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 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 ...
An oxygen concentrator takes in air and removes nitrogen from it, leaving an oxygen-enriched gas for use by people requiring medical oxygen due to low oxygen levels in their blood. [4] Oxygen concentrators provide an economical source of oxygen in industrial processes, where they are also known as oxygen gas generators or oxygen generation plants .
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 membrane barrier, leading to the development of high-performance microporous hollow-fibre oxygenators that eventually ...
Depending on the indication for extracorporeal membrane oxygenation, there are two common set-ups: veno-arterial (VA) and veno-venous (VV). In some instances the initial set-up can be transferred to a hybrid set-up. [citation needed]
Authorities in New York City are searching for a man who allegedly impersonated a federal immigration enforcement agent before trying to rape a 51-year-old woman in broad daylight, according to ...
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 ...
