How should a non-responsive casualty be monitored?

Monitoring a non-responsive casualty is critical to ensure their safety and determine if their condition is deteriorating or improving. Regular assessment of vital signs is essential because it provides objective data about the casualty's physiological status, including heart rate, respiratory rate, and blood pressure. These vital signs can reveal if the casualty is in shock or experiencing other critical issues that require immediate medical attention.

While frequent checks of skin color can be helpful in assessing circulation or oxygenation, it does not provide a comprehensive view of the casualty's overall physiological condition. Continuous contact for reassurance, while it may be beneficial for maintaining a psychological connection, does not substitute for medical assessments that indicate physical health. Limiting movement is important in some cases, especially if there is concern about spinal or other injuries, but it does not provide ongoing monitoring of the vital functions necessary for assessing the casualty's status in a potentially life-threatening situation.
