What should you do if your dive computer indicates an oxygen exposure warning?

When your dive computer indicates an oxygen exposure warning, it's crucial to understand that this is a serious alert regarding your current level of oxygen exposure while diving with enriched air nitrox. The correct course of action is to monitor your dive time and adjust accordingly.

This choice emphasizes the importance of being aware of your oxygen exposure throughout the dive rather than reacting hastily. The dive computer is designed to help you manage your exposure to prevent harmful effects associated with high levels of oxygen, such as oxygen toxicity. By carefully monitoring dive time and being judicious about depth and duration, you can safely navigate the rest of your dive while minimizing the risk of exceeding safe oxygen exposure limits.

Adjusting your dive plan for future dives is indeed important, but that should occur after assessing the current dive situation. Simply ascending immediately or ignoring the warning if you feel fine are both harmful choices, as they dismiss the guidance provided by the dive computer and could lead to serious health risks. It’s essential to respond intelligently to indications from your dive computer to ensure safe diving practices.
