Following return of spontaneous circulation after an out-of-hospital cardiac arrest, an intubated patient has oxygen saturations of 100 percent on high-flow oxygen, a stable blood pressure and a high end-tidal carbon dioxide.

Correct answer: ETitrate oxygen to a saturation of 94 to 98 percent and ventilate to normocapnia.

After return of spontaneous circulation, oxygen is titrated to a saturation of 94 to 98 percent to avoid the harm of hyperoxia, while ventilation targets normocapnia. Routine hyperventilation reduces cerebral perfusion. Waiting for blood gases before adjusting clearly excessive oxygen is inappropriate in the pre-hospital phase.
