Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Several studies show how patients with hyperoxia after cardiac arrest has increased mortality, but the association of hyperoxia before cardiac arrest and myocardial damage has never been investigated. Neither has the association between hyperoxia after cardiac arrest and myocardial injury.

Our research hypothesis is that hyperoxia before cardiac arrest aggravates myocardial damage, secondly we wish to analyze the association between hyperoxia after cardiac arrest and myocardial injury.

The exposure variables is oxygenation within 48 hours before and 48 hours after cardiac arrest, our primary outcome is myocardial damage and will be measured as peak troponin within 30 days after cardiac arrest.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Hypoxia

Defined as a group of patients with oxygen saturation \<94 % irrespective of supplemental oxygen.

If COPD, defined as oxygen saturation \<88 % irrespective of supplemental oxygen.

Oxygenation

Intervention Type OTHER

Oxygenation measured as oxygen supply and saturation before cardiac arrest, and oxygenation measured as PaO2 after cardiac arrest.

Normoxia

Defined as a group of patients with oxygen saturation 94 % - 98 % in combination of supplemental oxygen, or oxygen saturation \>94 % without supplemental oxygen.

If COPD, defined as oxygen saturation 88 % - 92 % in combination of supplemental oxygen, or oxygen saturation \>88 % without supplemental oxygen.

Oxygenation

Intervention Type OTHER

Oxygenation measured as oxygen supply and saturation before cardiac arrest, and oxygenation measured as PaO2 after cardiac arrest.
