Which condition is described as oxygen toxicity?

Oxygen toxicity refers specifically to the adverse physiological effects that occur when the body is exposed to high partial pressures of oxygen, typically occurring during deep dives when divers use enriched oxygen mixes like Nitrox or when they are at depths that exceed certain limits when breathing pure oxygen. When oxygen is inhaled at high concentrations or under high pressure, it can lead to central nervous system effects such as convulsions and other neurological symptoms, as well as lung irritation and damage.

Understanding the specific thresholds and conditions under which oxygen toxicity occurs is crucial for divers, as it informs safe diving practices and the management of gas mixes. This knowledge helps in preventing dangerous situations that can arise from exposure to excessive oxygen pressures. Other options may mention low-pressure mixtures or decompression sickness, but they do not pertain to the physiological reactions caused by high partial pressures specifically linked to oxygen toxicity.
