🧠 Hyperoxia in Acute Brain Injury: Friend or Foe? Abstract: This commentary responds to Romero-García et al.’s meta-analysis linking arterial hyperoxemia (PaO₂ elevation) to worse neurological outcomes in acute brain injury (ABI). The authors argue that equating hyperoxemia with cellular hyperoxia and oxidative injury is an oversimplification. Physiological evidence shows that oxygen transport is constrained […]
