  1. Baseline pulmonary capillary wedge pressure and cardiac output values are also shown in the lower part. None of the baseline differences between treatment arms are statistically significant.
  2. FS, femoro-subclavian; FF, femoro-femoral; CO, cardiac output; CoPP, coronary perfusion pressure; CPR, cardiopulmonary resuscitation; CVP, central venous pressure; MAP, mean arterial pressure
