ATS — ATS 2026 noninvasive support for acute hypoxemic respiratory failure
ATS, 2026
For adults with acute hypoxemic respiratory failure, ATS strongly recommends HFNC over standard oxygen and conditionally supports NIV or CPAP. Monitor closely and intubate promptly when noninvasive support fails. The recommendations primarily reflect reduced intubation, not a guaranteed mortality benefit.
