Despite its historical use, the evidence review leading up to the AHA Guidelines does not recommend the routine use of oxygen therapy in patients with uncomplicated AMI or ACS who have no signs of hypoxemia or heart failure [15]. Among patients with STEMI and without hypoxia, a randomized trial comparing supplemental oxygen versus no supplemental oxygen, initially in the EMS setting and continued into the hospital, showed no evidence of benefit and larger infarct size among those given oxygen [28]. The guidelines do, however, recommend oxygen administration if the patient is dyspneic or has an arterial oxyhemoglobin saturation <94%, signs of heart failure, or shock.
