What is the primary medicative response to a diver experiencing oxygen toxicity?

The primary medical response to oxygen toxicity is to administer pure oxygen and provide immediate medical assistance. In scenarios of oxygen toxicity, particularly when a diver experiences symptoms like visual disturbances, twitching, or dizziness, the situation is critical. High concentrations of oxygen in the body can lead to harmful effects, and administering pure oxygen can help to alleviate these symptoms by improving oxygen delivery to tissues and assisting in the removal of toxic oxygen radicals.

Moreover, immediate medical assistance is crucial because oxygen toxicity may lead to further complications, such as seizures. Therefore, responding quickly by ensuring the diver receives pure oxygen and medical intervention is essential for their safety and health.

While other options like encouraging gradual ascent or using emergency flotation devices may be relevant in some emergencies or diving scenarios, they are not the primary response to oxygen toxicity. Cold compresses may provide comfort but do not address the underlying issue of oxygen toxicity and are not part of standard protocols for managing this condition.
