Safety of Inhaled Hydrogen Gas Mixtures in Healthy Volunteers

Summary

Hydrogen gas may decrease the degree or incidence of brain injury following ischemia. The purpose of this study is to determine the safety and tolerability of inhaled hydrogen gas at the dose exposures required for a clinical efficacy study in healthy adult participants. Participants will breathe a gas mixture that contains a low concentration of hydrogen gas in air through a high flow nasal cannula. Investigators will test for any changes in breathing and neurologic status, as well as lab tests during and following the exposure period.
