What does drsabcd stand for with casualety who is not breathing ant not conscious?

DRSABCD is a first aid mnemonic that stands for Danger, Response, Send for help, Airway, Breathing, CPR, and Defibrillation. In the case of a casualty who is not breathing and unconscious, you would first ensure the area is safe (Danger), check for responsiveness (Response), call for emergency help (Send for help), open the airway (Airway), check for breathing (Breathing), and if there’s no breathing, start CPR. If an Automated External Defibrillator (AED) is available, it should be used as soon as possible (Defibrillation).
