Different sites of VA ECMO arterial cannulation and arterial catheter placement.

Arterial CannulaLocation of mixingArterial catheter siteComments

Right common carotid arteryAortic archAvoid right radialRight radial blood gases inaccurate due to sampling of immediate downstream arterialized blood
Right axillary arteryAortic archAvoid right radialRight radial blood gases not reflective of blood to which rest of body is exposed
Left axillary arteryAortic archAvoid left radialLeft radial blood gases not reflective of blood to which rest of body is exposed
Femoral arteryBetween aortic root and descending aorta—exact location depends on native cardiac output and magnitude of retrograde flowPreferred site right radial
Avoid dorsalis pedis of cannulated limb
Right radial cannulation detects upper body hypoxemia (see text)
