What should a bystander be used for when assisting with a backboard?

In situations where a backboard is being used, such as in the transport of an injured person, it is crucial to have proper support and stabilization to prevent further injury. The role of a bystander in this context is to help control and support the backboard during the lifting and moving process. This assistance ensures that the backboard is held steady while the patient is being transferred onto it or while being moved to a more suitable location. The bystander's involvement can help maintain the safety and comfort of the injured person and reduce the chances of exacerbating any potential spinal injuries.

While providing emotional support, monitoring vital signs, and guiding movements can be important roles in different contexts, they do not specifically relate to the physical handling and stabilization of the backboard during transport. The primary focus in this scenario is on ensuring that the backboard remains stable and supports the patient effectively.
