What does the "ABC" in patient assessment stand for?

The "ABC" in patient assessment stands for Airway, Breathing, and Circulation, which are the three critical steps in evaluating a patient's essential physiological functions and ensuring their survival.

In medical emergencies, the first priority is to assess and secure the airway to ensure that it is clear and unobstructed. Following this, the healthcare provider assesses the patient's breathing to determine if they are ventilating adequately and if oxygenation is sufficient. Finally, circulation is evaluated to check for effective blood flow, which is essential for delivering oxygen and nutrients to the body's tissues.

This sequence is fundamental in resuscitation and emergency care, as ensuring that the airway is open, the patient is breathing effectively, and there is adequate circulation can help prevent further complications and is vital for improving outcomes in critical situations.
