Buddy breathing

Buddy breathing is a rescue technique used in scuba diving, free diving, and underwater diving where two divers share a single air source. This technique is typically used in emergency situations when one diver's air supply has failed or been depleted.

History

The concept of buddy breathing originated in the early days of scuba diving when divers used twin-hose regulators. These regulators had a mouthpiece that could be easily shared between two divers. As single-hose regulators became more popular, the practice of buddy breathing became less common due to the increased difficulty of sharing a single mouthpiece. However, the technique is still taught and practiced in some diving communities.

Technique

Buddy breathing involves one diver providing their dive buddy with air from their own regulator. The diver with the functioning air supply takes a breath, then passes the regulator to their buddy who also takes a breath. This process is repeated until both divers can safely reach the surface or another air source.

The technique requires good communication and coordination between divers. It is important for both divers to remain calm and avoid panicking, as this can lead to rapid consumption of the remaining air supply.

Safety Considerations

While buddy breathing can be a lifesaver in emergency situations, it also carries risks. If not performed correctly, it can lead to both divers running out of air. For this reason, many diving organizations recommend carrying a redundant air supply, such as a pony bottle or spare air, as a safer alternative to buddy breathing.

Training

Training in buddy breathing is offered by some diving certification organizations. The training typically involves classroom instruction, pool practice, and open water dives. Divers are taught how to share air, communicate underwater, and manage stress in emergency situations.
