What condition results from increased exposures to elevated partial pressure of oxygen levels?

Oxygen toxicity occurs when there is an excessive exposure to elevated partial pressures of oxygen, particularly when divers breathe oxygen at pressures greater than what is normally found at sea level. Increased partial pressure of oxygen can lead to harmful physiological effects on the body, primarily affecting the central nervous system and lungs.

Under normal conditions, the body can tolerate certain amounts of oxygen; however, when divers use pure oxygen or are exposed to increased depth, the amount of oxygen that the body absorbs can become detrimental. Symptoms of oxygen toxicity can include visual disturbances, nausea, twitching, seizures, and other neurological impairments. This is particularly relevant in environments such as deep diving or when using enriched oxygen mixes, where the partial pressure of oxygen exceeds safe limits.

Understanding this condition is crucial for divers, as managing exposure to elevated oxygen levels is a key component of dive planning to avoid serious health issues.
