In tactical field care, what is the first assessment performed on a casualty?

In tactical field care, the first assessment performed on a casualty is the primary survey, which includes the critical evaluation of airway, breathing, and circulation. This initial assessment is paramount because it focuses on identifying and addressing any life-threatening conditions that could compromise the casualty's survival.

The primary survey is performed systematically to ensure that the most critical aspects of the casualty's condition are evaluated and managed first. Securing an open airway is essential, as an obstructed airway can lead to respiratory failure and death within minutes. Following airway assessment, breathing is examined to determine if the casualty is ventilating adequately. Finally, circulation is assessed to identify any signs of shock or severe bleeding, which require immediate intervention.

By prioritizing these vital functions, the medic can quickly triage the situation, ensuring that any potentially life-threatening issues are addressed as a priority before moving on to further assessments and treatments. This structured approach is fundamental in tactical combat scenarios where time and swift action are critical.
