In the event of an air emergency, sharing air from your alternate source is the first logical action to take. This is essential because it directly addresses the diver's need for breathable air, which is critical for survival and safety. By using a buddy's alternate air source, the diver can stabilize the situation and control the ascent more safely while maintaining communication with their diving partner.

Maintaining continuous access to air helps prevent panic, promotes effective decision-making, and ensures that the diver remains conscious and capable of executing further safety measures, such as a controlled ascent. This procedure emphasizes the importance of teamwork in diving, as well as the need for divers to be prepared for such emergencies by practicing air-sharing techniques.

Staying calm and remaining underwater could lead to increasing risks, as oxygen supply diminishes. Signaling for help could be ineffective in an immediate emergency where time is of the essence, and a rapid ascent may result in complications such as barotrauma or decompression sickness if the situation is not handled properly. It is crucial to manage the emergency with the tools available, making the air-sharing option the preferred initial response.
