Inhalation of high-concentration hydrogen gas attenuates cognitive deficits in a rat model of asphyxia induced-cardiac arrest

How Hydrogen Gas May Help Protect the Brain After Cardiac Arrest

A 2019 study found that inhaling high-concentration hydrogen gas may help reduce cognitive deficits after cardiac arrest. The research, conducted on rats, suggests that hydrogen gas may have antioxidant properties that protect the brain from damage. This discovery has important implications for humans and could potentially improve outcomes for people who experience cardiac arrest.
