What are the two types of oxygen toxicity?

The correct answer identifies the two primary types of oxygen toxicity as central nervous system (CNS) toxicity and pulmonary toxicity.

CNS toxicity occurs when a person is exposed to high partial pressures of oxygen, typically at depths encountered during deep diving or hyperbaric treatments. The symptoms include visual disturbances, muscle twitching, anxiety, and seizures, which can arise from the effects of oxygen on the nervous system. This condition becomes critical in scenarios where divers may experience increased pressure and the associated risks of high oxygen levels.

Pulmonary toxicity, on the other hand, refers to lung injury resulting from prolonged exposure to elevated oxygen levels, often seen in hyperbaric environments or inappropriately managed oxygen therapy. The symptoms can range from irritation of the airways to more severe conditions such as pulmonary edema, which can pose additional risks during rescue operations or therapeutic interventions.

Understanding these types of oxygen toxicity is crucial for safety and efficacy in situations where oxygen levels are manipulated, particularly in undersea rescue operations where divers encounter varying pressures and oxygen exposures.
