Summary

This study tests whether adding a small amount of hydrogen to the breathing gas can reduce lung damage caused by breathing high levels of oxygen under pressure. Thirty-two healthy military divers will breathe either hydrogen-enriched or normal oxygen gas during two separate sessions. The goal is to see if hydrogen lowers oxidative stress and protects lung function.
