How do you recognize and respond to symptoms of toxicity while diving?

Recognizing and responding to symptoms of toxicity while diving is crucial for safety. Ascending immediately to shallower depths is the appropriate response when unusual physical sensations or symptoms of toxicity are noticed. This action helps to alleviate the effects of nitrogen and oxygen pressures at deeper depths, potentially mitigating the severity of the symptoms.

Diving with a higher oxygen concentration, such as that found in enriched air nitrox, can lead to specific symptoms of oxygen toxicity, particularly if the depth exceeds the recommended limits or if the dive time surpasses safe allowances. Symptoms may include visual disturbances, dizziness, or altered mental states. When divers notice these signs, ascending promptly allows for a reduction in the partial pressure of oxygen, which can prevent more serious complications associated with toxicity.

Upon recognizing symptoms, it is vital to take immediate action rather than ignoring minor signs, as they may escalate quickly. Focusing solely on buoyancy control while feeling unwell is unwise, as it may divert attention from critical health issues that require immediate attention. In summary, ascending to shallower depths is the most effective response to combat the potential adverse effects of diving under enriched air conditions.
