oxygen toxicity
Too much O2
Oxygen toxicity is damage to body tissues caused by breathing oxygen at elevated partial pressures—typically during deep diving or medical oxygen therapy.
High oxygen concentrations can trigger seizures, vision problems, or lung damage.
Divers manage the risk by limiting depth and exposure time when using oxygen-rich breathing mixtures.
