Found insideThis comprehensive guide presents clinicians with the latest developments in the diagnosis and management of atrial fibrillation. Cannulation for VA ECMO can be central or peripheral. Blood is drained from the venous system and pumped through a membrane oxygenator where it is oxygenated. CPR is ongoing. It may be used at low flows (2-3 L/min) as partial assistance to native cardiac output or at higher flows (4-6 L/min) completely replacing native cardiac output. 3 Above all else, prompt recognition of clinical deterioration, pathology, and initiation of VA-ECMO in . 2020 Sep 24;4:189-192. doi: 10.1016/j.xjtc.2020.09.016. The access cannula is usually placed in the inferior vena cava via the femoral vein. For placement of the arterial cannula, the right axillary artery is exposed lateral and inferior to the clavicle at the deltopectoral groove. Cannulation centrally through the chest is a viable option and is commonly used following failure to wean from bypass.
