*. The REDOX-AHF randomized trial showed that a restrictive oxygen strategy (SpO₂ ~90%) in acute heart failure patients achieved better pulmonary decongestion and signals toward improved outcomes compared with liberal oxygen therapy (~96%), without increasing dyspnea or severe hypoxia. The study raises important concerns about potential harm from unnecessary hyperoxia in acute HF.
