Title: Blood Pressure and Oxygenation Targets in Post-resuscitation Care, a Randomized Clinical Trial
Brief Summary: This study compares two blood pressure targets and two oxygenation targets in the post-resuscitation care of comatose out-of-hospital cardiac arrets patients. Using a novel method the blood pressure-intervention is double-blinded. The oxygenation-intervention is open-label. As a subordinate study, the patients will be randomized 1:1 to active fever-control with an automated feedback temperature control-device for 36 or 72 hours following return of spontaneous circulation.


Options:
A: Inclusion Criteria:

1. Age ≥18 years
2. OHCA of presumed cardiac cause
3. Sustained ROSC
4. Unconsciousness (GCS \<8) (patients not able to obey verbal commands) after sustained ROSC

Exclusion Criteria:

1. Conscious patients (obeying verbal commands)
2. Females of childbearing potential (unless a negative HCG test can rule out pregnancy within the inclusion window)
3. In-hospital cardiac arrest (IHCA)
4. OHCA of presumed non-cardiac cause, e.g. after trauma or dissection/rupture of major artery OR Cardiac arrest caused by initial hypoxia (i.e. drowning, suffocation, hanging).
5. Known bleeding diathesis (medically induced coagulopathy (e.g. warfarin, NOAC, clopidogrel) does not exclude the patient).
6. Suspected or confirmed acute intracranial bleeding
7. Suspected or confirmed acute stroke
8. Unwitnessed asystole
9. Known limitations in therapy and Do Not Resuscitate-order
10. Known disease making 180 days survival unlikely
11. Known pre-arrest CPC 3 or 4
12. \>4 hours (240 minutes) from ROSC to screening
13. Systolic blood pressure \<80 mm Hg in spite of fluid loading/vasopressor and/or inotropic medication/intra-aortic balloon pump/axial flow device
14. Temperature on admission \<30°C.
B: Inclusion Criteria:
