Which of the following is a symptom of oxygen toxicity?

Oxygen toxicity can occur when a person is exposed to high concentrations of oxygen for prolonged periods, leading to various symptoms. Seizures are a significant indication of oxygen toxicity, particularly in the context of high doses of oxygen experienced during hyperbaric oxygen therapy or in other medical scenarios where oxygen levels are elevated.

The reason seizures are associated with oxygen toxicity relates to the neurotoxic effects of oxygen on the central nervous system. The excessive presence of oxygen can result in oxidative stress and the formation of free radicals, which can ultimately lead to neuronal damage and excitotoxicity. This heightened neuronal activity can manifest as seizures, indicating severe oxygen toxicity.

While headaches, shortness of breath, and chest pain can occur due to various respiratory or cardiovascular conditions, they are not specific indicators of oxygen toxicity. In cases of oxygen toxicity, the onset of seizures reflects a more severe impact of high oxygen levels on the body, demonstrating the potential danger involved with excessive oxygen exposure.
