It's possible you're thinking of "DR ABC", which stands for:
* Danger: Check for immediate danger to yourself and the patient.
* Response: Assess the patient's responsiveness (e.g., shout, gently shake, pinch).
* Airway: Check for airway obstruction (e.g., look, listen, feel).
* Breathing: Check for breathing (e.g., look, listen, feel).
* Circulation: Check for circulation (e.g., pulse, skin color, temperature).
This is the standard primary survey mnemonic used in first aid and emergency medicine.
