How does one assess an injured diver’s vital signs?

The assessment of an injured diver's vital signs is crucial in determining their condition and the appropriate response needed. Checking the pulse, breathing rate, and responsiveness provides a comprehensive picture of the diver's physiological state.

The pulse gives insight into the heart rate and rhythm, which can indicate shock or other cardiovascular issues. The breathing rate helps assess the effectiveness of the diver's respiratory function, crucial in cases of potential underwater lung injuries or hypoxia. Responsiveness checks the diver's level of consciousness, allowing responders to gauge neurological status and the severity of any injuries.

This multifaceted approach to vital signs is essential because it not only identifies immediate life-threatening conditions but also informs the decision-making process for further intervention and care. Other methods, such as merely checking mental state, looking for visible injuries, or asking the diver how they feel, do not provide a complete understanding of the diver's medical condition and are supplementary rather than primary methods for assessment.
