If a diver experiences rapid buoyancy changes, the appropriate response is to immediately slow or stop their ascent. This action is critical for preventing potential injuries associated with decompression sickness or barotrauma, which can occur if a diver ascends too quickly.

When buoyancy changes happen rapidly, such as due to a sudden loss of weight or changes in gas expansion within the body, ascending too quickly can result in nitrogen bubbles forming in the tissues and bloodstream, leading to serious health risks. By responding appropriately and controlling the ascent, the diver allows for a more gradual adjustment to the surrounding pressure, which minimizes the risks associated with rapid depth changes.

Maintaining ascent control is vital not just for safety but also for ensuring that any trapped gases can safely expand and escape without causing damage to body tissues. Therefore, slowing or stopping the ascent is the best course of action.
