What should a supervisor do if a diver reports breathing difficulty?

• A. Continue the dive
• B. Increase air supply
• C. Stop the dive and initiate emergency procedures
• D. Ignore the issue

Answer: (C)

Breathing difficulty is a red flag that something serious may be happening with the diver or their equipment, so the supervisor must act immediately. The first step is to stop the dive and follow the emergency procedures. This pause allows you to assess the situation, verify equipment (regulator, tank, mask fit), ensure the buddy is safe, and start appropriate care. Providing high-concentration oxygen and arranging medical evaluation or a rapid ascent as dictated by the symptoms are key actions. Continuing the dive or trying to push more air without addressing the underlying cause could let a potentially life-threatening condition worsen, while ignoring the issue is simply unsafe. The goal is to stabilize breathing, support the diver, and get professional help as quickly as possible, following the emergency action plan.
