What is the correct order of components to check during the primary survey?

The primary survey is a critical phase in assessing a patient in an emergency situation, following the ABC approach, which stands for Airway, Breathing, and Circulation. This sequence is essential because it prioritizes the most immediate threats to life.

Starting with the airway ensures that there are no obstructions that could prevent the patient from receiving oxygen. If the airway is compromised, it is the first issue that needs to be addressed to allow for breathing to occur. Once the airway is confirmed to be open, the next step is to assess breathing. This involves checking the patient's ability to breathe effectively, as adequate respiration is crucial for oxygen delivery to tissues.

Finally, circulation is assessed to evaluate the patient's heart function and blood flow. This includes checking for pulse, assessing skin color, and any signs of bleeding. Since circulation relies on the airway being open and effective breathing, this order of assessment ensures that the most critical issues affecting the patient's survival are addressed first.

Thus, the correct order of components to check during the primary survey is Airway, Breathing, and then Circulation. This systematic approach allows responders to quickly identify and manage life-threatening conditions.
