First aid is treatment given before emergency medical assistance arrives to preserve life, prevent worsening of conditions, and promote recovery. A first aider's responsibilities are to rapidly but calmly assess the situation, make an accurate diagnosis, and provide immediate and appropriate care. The primary assessment checks for responsiveness, ensures an open airway, checks breathing and circulation. Diagnosis principles include taking history from bystanders, asking the casualty about symptoms, and the first aider's observations of signs.
