What is one potential effect of oxygen toxicity?

Oxygen toxicity can manifest in serious health effects primarily due to elevated partial pressures of oxygen, which can occur when divers breathe oxygen-rich environments. When oxygen levels are too high, it can lead to central nervous system effects, such as seizures, visual disturbances, and changes in consciousness. These symptoms arise because excessive oxygen can affect brain function and lead to neurological impairment.

Additionally, oxygen toxicity can result in lung damage, particularly in environments where divers are exposed to high pressures of oxygen, such as when using enriched air or during deep dives. Elevated levels of oxygen can cause inflammation and damage to lung tissue, which may result in symptoms like chest pain and difficulty breathing.

The other options, while they may relate to divers in different contexts, do not specifically capture the primary and critical effects associated with oxygen toxicity, which is a significant concern during diving activities. Thus, the comprehensive understanding of oxygen’s impact on the body, especially concerning the central nervous system and the lungs, underscores why this is the correct choice.
