High-Flow Oxygen’s Survival Benefit Debunked in Respiratory Failure

In a large randomized trial, treating patients with acute hypoxemic respiratory failure with high-flow oxygen didn’t improve survival compared with standard oxygen. However, high-flow oxygen did reduce intubation as a secondary endpoint. Experts suggested that the findings recalibrate expected benefits but also shore up the rationale for early use of high-flow oxygen in appropriate patients….
