The role of oxygenation during critical illness remains a major question. Is extra oxygen harmful or helpful? What oxygen levels should we target, both for respiratory failure and for patients after cardiac arrest? Dr. Benjamin Abella discusses these topics, and reviews a hot-of-the-press work from European investigators (the “HOT-ICU”) trial, published in New England Journal of Medicine this month. The paper evaluates two different oxygen targets for patients with respiratory failure – implications for this work as it pertains to cardiac arrest will be discussed.
