During a rescue dive, why is buoyancy control crucial?

Buoyancy control is crucial during a rescue dive primarily because it ensures the safety of the victim during the ascent. When conducting a rescue, maintaining optimal buoyancy allows the rescuer to manage the ascent rate effectively, which is vital for avoiding rapid ascents that can lead to decompression sickness in both the rescuer and the victim. Proper buoyancy enables the rescuer to maintain control while ascending and ensures that the victim is not subjected to harmful pressures or turbulence in the water that could exacerbate their condition. In addition, good buoyancy control helps in managing the victim’s position in the water, minimizing the risks associated with the ascent and providing a stable environment as both the rescuer and the victim make their way back to the surface safely.
