Oxygen therapy guidelines

There has been increasing realisation over the past several years of the potential harm associated with excess oxygen administered to adult patients and that we should be more considered in our use of oxygen therapy in acute care settings. Recent guidelines published in the BMJ “Oxygen therapy for acutely ill medical patients: a clinical practice guideline” highlight that saturations of 96% should be the upper maximum targeted and that oxygen therapy is not indicated when oxygen saturations are 93% or higher and probably should not be administered when saturations are 90-92%.
