Snippet: Given an oxygen binding capacity of 1.34ml/g hemoglobin, this translates to an oxygen transport capacity at a normal hemoglobin content of ECMO blood of up to 200ml/L x 3.5L/min, i.e. 700ml oxygen/min; at a hypothetical venous oxygen saturation of 60% with a near-normal body oxygen consumption of approximately 125ml/min/m 2 , even taking some venous/ECMO recirculation and some anemia into account, such an Impella CP-based adhoc ECMO will still re.....
