Because stress can play a pivotal role in causing and complicating Scuba diver emergencies, as a Rescue Scuba Diver you need to learn to recognize stress in both yourself and other Scuba divers. This enables you to prevent stress-caused emergencies, and to manage emergencies more effectively when they happen.

To recognize stress, you apply two broad steps. First, you observe Scuba diver behavior characteristics that indicate stress. These characteristics usually, but not always, manifest themselves as a behavior change. Second, you verify the meaning of the behavior. Most of the time, you simply ask the Scuba diver about what you observed.
