What critical information should be communicated during the evacuation phase?

During the evacuation phase, it's essential to communicate critical information that directly impacts the care and safety of the casualty. Sharing details about the mechanism of injury is vital, as it informs medical personnel about potential complications and the nature of the injuries sustained. Additionally, discussing the treatments provided ensures that incoming medical teams are aware of any interventions that have already been performed, which helps avoid redundant measures and guides further treatment decisions. Lastly, noting any changes in the casualty's condition can alert medical teams to evolving health risks or urgent needs that require immediate attention upon arrival. This comprehensive communication helps facilitate a smoother transition of care and optimizes the casualty’s chances of recovery.
