What does the acronym "ABC" stand for in medical emergencies?

In medical emergencies, the acronym "ABC" stands for Airway, Breathing, and Circulation. This sequence is critical in the assessment and management of a patient who is unresponsive or in distress.

The primary concern in emergencies is to ensure that the airway is clear and unobstructed, as any compromise in airway integrity can rapidly lead to respiratory failure and death. Once the airway is maintained, the focus shifts to evaluating the patient's breathing: is the patient breathing adequately and effectively? If not, interventions such as rescue breaths or oxygen administration may be necessary. Finally, circulation pertains to the heart and blood flow; one must assess whether the patient has a pulse and if their circulatory system is functioning properly. If circulation is compromised, immediate actions such as CPR may be required to restore blood flow to vital organs.

This systematic approach allows responders to prioritize life-saving interventions effectively in acute situations, thereby improving the chances of a positive outcome for the patient. Other options provide incorrect or incomplete sequences that do not align with the established protocols for emergency care.
