After a medical issue is identified in a diver, what is the appropriate action regarding medical fitness for further operation?

• A. Reevaluate medical fitness and adjust the dive plan accordingly.
• B. Proceed with the same plan regardless.
• C. Discontinue all diving permanently.
• D. Consult a physician only after the next scheduled dive.

Answer: (A)

When a medical issue is identified, the diver should have their medical fitness reevaluated and the dive plan adjusted accordingly. Health changes can alter how a person tolerates pressure changes, gas absorption, and emergency situations, so a current medical assessment is essential to keep diving safe.

This means seeking a medical evaluation and, if needed, a new clearance from a physician who understands diving. Based on that evaluation, the dive profile may be modified—such as reducing depth or bottom time, changing surface intervals, or other restrictions—or diving may be temporarily or permanently deferred. Continuing with the same plan regardless of the new issue keeps the diver exposed to unnecessary risk, and waiting until the next scheduled dive to seek medical advice delays essential safety precautions. Permanent retirement from diving is only appropriate if a medical condition truly contraindicates all diving, as determined by a medical professional.
