The recommended action upon noticing symptoms of CNS Oxygen Toxicity while underwater is to begin a controlled ascent together. This response is critical to ensure the safety of the diver experiencing symptoms, as CNS Toxicity can present serious risks, including loss of consciousness or seizures.

By conducting a controlled ascent, divers can safely mitigate the effects of elevated oxygen levels while ensuring that the affected diver is closely monitored and assisted. This approach minimizes the risk of further complications, such as panic, rapid ascents, or the potential for barotrauma.

Additionally, ascending together allows buddies to manage the situation more effectively and helps ensure that both divers reach the surface safely while adhering to proper ascent rates and safety stops, if applicable. This is particularly important in scenarios involving CNS Oxygen Toxicity, where adherence to safe diving practices is paramount for avoiding accidents or health issues.
