patients on Extracorporeal Membrane Oxygenation veno-venous
major patients admitted to the general intensive care unit on Extracorporeal Membrane Oxygenation veno-venous
|
Part of the biology data is used from the patient's routine blood tests.
Additional blood samples are taken from an arterial catheter already in place.
They are performed over 4 periods: one just before start ECMO and 3 under ECMO at 3-day intervals
