What does not qualify as an action taken in an out-of-air emergency?

In an out-of-air emergency, the priority is to manage the situation safely and effectively to ensure a diver's ascent to the surface without risking injury. Continued swimming towards the surface without taking appropriate safety measures does not qualify as an action that would be taken in such an emergency.

The ideal responses in this scenario involve utilizing available resources or assistance. Using an alternate air source or a diving buddy's octopus are both proactive measures aimed at managing the emergency by providing a means of breathing while ascending. Controlling ascent is also crucial because a rapid ascent can lead to serious injuries such as decompression sickness or lung barotrauma. Therefore, actions taken during an out-of-air emergency should focus on accessing air and ensuring a safe ascent rather than simply swimming towards the surface without a plan.
