When assessing a patient, what does the “A” in the acronym ABC stand for?

The “A” in the acronym ABC stands for "Airway." In medical emergencies, maintaining a clear and patent airway is the foremost priority for any healthcare provider. The ABC approach is fundamental in assessing and managing patients, particularly in life-threatening situations. Securing the airway ensures that oxygen can reach the lungs; if the airway is compromised, the patient is at risk of respiratory failure, which can quickly lead to serious complications or death.

Understanding this sequence is crucial for effective patient care because once the airway is confirmed as open and clear, the focus can then shift to breathing and circulation. This systematic approach helps medical professionals prioritize interventions effectively, which is vital during emergency scenarios or encounters with critically ill patients.
