Argon inhalation attenuates systemic inflammation and rescues lung architecture during experimental neonatal sepsis

This preclinical study demonstrates that argon inhalation (70% Ar/30% O2) significantly improves survival and reduces systemic inflammation in a neonatal mouse sepsis model. The therapy attenuates cytokine release and preserves lung architecture, suggesting potential as an adjunct treatment for mechanically ventilated septic neonates.
