What does CHAT mean in first aid?

In first aid, CHAT is an acronym that stands for "C" for "Circulation," "H" for "Hypoxia," "A" for "Airway," and "T" for "Trauma." It serves as a quick assessment tool to identify critical areas of concern when responding to a medical emergency. The focus is on ensuring proper circulation, oxygenation, airway management, and addressing any traumatic injuries. This systematic approach helps first responders prioritize care effectively.
