Oxygen toxicity refers to the negative effects that occur from too much oxygen exposure, particularly in medical settings. Some synonyms for this term include hyperoxia, oxygen poisoning, and oxygen toxicity syndrome. Hyperoxia reflects the high levels of oxygen that lead to oxidative stress on cellular structures and tissues. Oxygen poisoning emphasizes the dangerous effects that oxygen can have on the body, much like a toxic chemical substance. Oxygen toxicity syndrome refers to the collection of symptoms that occur with prolonged oxygen exposure, including respiratory distress, seizures, and damage to vital organs. These synonyms provide different ways to understand and describe the potentially harmful effects of excess oxygen exposure.
