[20], Ranchordet al.RCT1366 L O2/minSTEMI-High-O2 therapy had no effect on mortality or infarct size

[26], Chirst et al.Retrospective cohort134-Cardiac arrest-Hyperoxia in the first 60 minutes after return of circulation is associated with better survival rates

[27], Lee et al.Retrospective cohort213-Cardiac arrest-Hypocarbia associated with in-hospital mortality. Hypoxemia and hyperoxemia associated with poor neurological outcome.
