Hyperoxia is respiratory disease caused by oxygen toxicity. It occurs when the organism is exposed to an higher than normal [partial pressure](Partial%20pressure.md) of oxygen. Hyperoxia leads to two possible effects : - The Lorrain Smith effect : pulmonary toxicity that can cause lung irritations. - The Paul Bert effect : CNS (Nentral Nervous System) toxicity that cause symptoms similar to an epilepsy crisis. Oxygen toxicity is something to have in mind when using [Nitrox](Nitrox.md) or [hyperoxic trimix](Hyperoxic%20trimix.md) in [scuba diving](Scuba%20diving.md). ## Links - [Oxygen toxicity - Wikipedia](https://en.wikipedia.org/wiki/Oxygen_toxicity) - [Hyperoxia - Wikipedia](https://en.wikipedia.org/wiki/Hyperoxia)
