What is the recommended action if a diver feels out of air?

If a diver feels out of air, the recommended action is to signal their buddy and begin a controlled ascent. This response is crucial for several reasons. First, signaling the buddy ensures that the diver is not alone in a potentially dangerous situation. Communication is vital underwater, and alerting a diving partner enhances safety and promotes a team approach to resolving the emergency.

Beginning a controlled ascent is equally important because it minimizes the risks associated with rapid ascents, such as decompression sickness or lung overexpansion injuries. Ascending slowly allows the body to naturally eliminate dissolved nitrogen from the tissues, which is crucial after potentially prolonged exposure to increased pressure.

Planning the ascent while managing air supply ensures the diver maintains safety protocols and increases the likelihood of surfacing without complications. This planned response is essential to dive safety and proficiency and teaches divers how to handle emergencies effectively.
