  1. Values of all parameters, with the exception of RecF, are expressed in L/min
  2. EBF extracorporeal blood flow; LV CO cardiac output, calculated from stroke volume (SV) and heart rate (HR) using the formula: LVCO = SV.HR; P CO cardiac output, measured using a pulmonary artery catheter; RecV recirculation volume, calculated using the formula: RecV = LVCO − PCO; RecF recirculation fraction, calculated using the formula: RecF = (RecV/LVCO) × 100
  3. * P < 0.05 compared with value at EBF 1 L/min
