  • Unconsciousness (GCS \<9) (patients not able to obey verbal commands) after sustained ROSC at the time of randomization

Exclusion

  • Females of childbearing potential if pregnancy is suspected (unless a negative HCG test can rule out pregnancy within the inclusion window)

  • Known pre-arrest CPC 3 or 4 functional status
  • \>3 hours (180 minutes) from ROSC to screening
  • Systolic blood pressure \<80 mm Hg despite fluid loading/vasopressor and/or inotropic medication (If the systolic blood pressure is recovering during the inclusion window of 180 minutes the patient may be included)
  • Use of intra-aortic balloon pump/axial flow device/ECMO (If the patient is weaned and the device is removed during the inclusion window of 180 minutes the patient may be included)
