In the CHEER trial [19] 15Fr arterial cannulae and 17Fr venous cannulae [21] (Medtronic, Minneapolis, MN USA) were used. The arterial cannula is advanced to the descending aorta, whilst the venous cannula is extended to the inferior vena cava. The positions of the respective guidewires is confirmed with a chest x-ray.

Extracorporeal membrane oxygenation (ECMO), is a form of extracorporeal life support, providing prolonged cardiac and respiratory support to persons whose heart and lungs are unable to provide an adequate amount of oxygen, gas exchange or blood supply to sustain life.
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).
The French scale, also known as the French gauge or Charrière system, is a widely used measurement system for the size of catheters.It is commonly abbreviated as Fr but may also be abbreviated as Fg, FR or F, and less frequently as CH or Ch (referencing its inventor, Charrière).
A venous cannula removes oxygen depleted venous blood from a patient's body, and an arterial cannula infuses oxygen-rich blood into the arterial system. The main determinants of cannula size selection is determined by the patient's size and weight, anticipated flow rate, and the size of the vessel being cannulated. [10]
Heated humidified high-flow therapy, often simply called high flow therapy, is a medical treatment providing respiratory support by delivering a flow of oxygen of up to 60 liters per minute to a patient through a large-bore or high-flow nasal cannula. Primarily studied in neonates, it has also been found effective in some adults to treat ...
Robert Bartlett (born May 8, 1939) is an American physician and medical researcher who is credited with developing a lifesaving heart-lung technology known as extracorporeal membrane oxygenation (ECMO). He is an emeritus professor of surgery at the University of Michigan Medical School.
