First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how healthy adults respond to breathing air with less oxygen for up to 7 days. Researchers measured oxygen levels in the blood, red blood cell production, and lung pressure to understand the body's adjustments. The goal was to define safety and basic responses, not to treat any disease.
