First seen Jan 11, 2026 · Last updated May 03, 2026 · Updated 21 times

Summary

This study looked at how hyperbaric oxygen therapy (breathing pure oxygen in a pressurized chamber) affects the smallest blood vessels in the body. Fifteen healthy volunteers were exposed to different oxygen levels and pressures, and researchers measured changes in their blood flow using special cameras and sensors. The goal was to understand the body's response, not to treat any disease.
