What is the correct order for the primary assessment of a patient?

The primary assessment of a patient follows the established sequence of Airway, Breathing, and Circulation, which is crucial for ensuring a systematic approach to emergency care.

Starting with the airway is essential because a clear airway is necessary for the patient to breathe and receive adequate oxygen. If the airway is obstructed, even if breathing and circulation are normal, the patient is at risk of respiratory failure.

Following the assessment of the airway, the next step is to evaluate breathing. This involves checking if the patient is breathing adequately and if not, initiating appropriate interventions such as providing rescue breaths or supplemental oxygen if necessary. Breathing directly affects the oxygenation of the patient's blood and tissues, making it critical to assess immediately after clearing or ensuring the airway is open.

Finally, circulation is assessed. This step involves checking the patient’s pulse, skin color, and signs of blood loss, which gives an indication of the patient's hemodynamic stability. By prioritizing circulation last in this sequence, it ensures that the more immediate threats to life from airway and respiratory issues are addressed first.

Thus, the order of Airway, Breathing, and Circulation is not just a guideline but a vital protocol that reflects the priority of maintaining life in a medical emergency.
