  1. N = 8, except at 60 min ROSC in the manual group were n = 3.
  2. Hbv = hemoglobin in venous blood; Hctv = hematocrite in venous blood; SaO2 and SvO2 = oxygen saturation in arterial and venous blood, respectively; PaO2 and PvO2 = partial oxygen pressure in arterial and venous blood, respectively; PaCO2 and PvCO2 = partial carbon dioxide pressure in arterial and venous blood, respectively; pHa and pHv = pH in arterial and venous blood, respectively; base excess a and base excess v = base excess in arterial and venous blood, respectively; lactate v and glucose v = lactate and glucose in venous blood. Blood gases are given at temperature-corrected values.
