What is the safest course of action if a diver has blocked air passages?

Assisting the diver in clearing their air passages is the safest and most appropriate course of action in this situation. Blocked air passages can lead to hypoxia, a condition where the body is deprived of adequate oxygen, which can quickly become life-threatening. By intervening to help clear the blockage, you can restore normal breathing and ensure the diver receives enough oxygen.

Waiting for the diver to clear the blockage naturally could lead to a worsening condition, as they may struggle and exhaust themselves in the process. Ascending slowly to the surface would not address the immediate problem of the blockage and could result in serious complications. Ignoring the situation entirely, regardless of whether the diver is in pain or not, overlooks the critical need for prompt assistance in respiratory emergencies. Therefore, directly assisting the diver is essential for their safety and well-being.
