When is a rescued diver most likely to sustain an injury?

The most likely time for a rescued diver to sustain an injury is during ascent. As divers begin to ascend, they may experience various physical stresses and challenges due to changes in pressure. If a diver is in distress or unresponsive, improper or rapid ascent can lead to serious injury such as decompression sickness or barotrauma. Additionally, if the rescue diver attempts to control the situation but fails to manage the ascent rate properly, it can lead to further complications for both the rescued diver and the rescuer.

It is important to note that while other situations such as descent, training, and swimming can pose risks, the ascent phase is critical for safety in diving. This is especially true for a rescued diver who may have compromised air management or be physically unable to follow proper ascent procedures. Hence, the focus on cautious and controlled ascents during rescue operations is essential to prevent injuries related to pressure changes.
