Oxygen Toxicity

Definition - What does Oxygen Toxicity mean?

Oxygen Toxicity is the condition that results from the harmful effects caused due to breathing molecular oxygen at the elevated partial pressures. It is a severe condition that is a cause of concern for underwater divers on the high concentrations of the supplemental oxygen and for those who undergo a hyperbaric oxygen therapy. It is caused by being exposed to oxygen with partial pressures greater than the pressures which the body is normally exposed to. Breathing of elevated partial pressures of oxygen may result in hyperoxia, which refers to excess amount of oxygen present in the body tissues.

Petropedia explains Oxygen Toxicity

Oxygen Toxicity affects the body in different ways based on the types of exposure. Ocular and pulmonary toxicity are as a result of elongated exposure to elevated levels of oxygen at normal pressure. The exposure of the body to the high partial pressures of oxygen greater than the atmospheric pressure for short time period causes central nervous system toxicity. The symptoms of Oxygen Toxicity include breathing issues, disorientation and changes in vision like myopia. The short term and long term exposures to very high and above normal oxygen partial pressures may cause the collapse of alveoli in the lungs, oxidative damages to the cell membrane, seizures and retinal detachment. A booming recovery from the most adverse kind of Oxygen Toxicity is possible.
