Oxygen therapy for acute myocardial infarction: a systematic review and meta-analysis. 2017;74:8–14.In the absence of robust evidence that oxygen is beneficial or harmful, patients with suspected acute myocardial infarction (AMI) should have oxygen therapy titrated to oxygen saturation levels in accordance with guidelines.A large randomised trial, Determination of the role of oxygen in suspected acute myocardial infarction (DETO2X-AMI),1 has recently reported no mortality difference at 365 days between normoxic patients with suspected AMI who received oxygen versus ambient suggesting supplementary oxygen can safely be withheld in such patients.Oxygen therapy has been a mainstay of emergency management of patients with suspected AMI for decades.
