This document provides guidelines for assessing and responding to medical emergencies and unconscious or collapsed patients. It outlines the DRS-ABC approach - check the patient's Danger, Response, Send for help, Airway, Breathing, and Circulation. It describes how to open the airway, give oxygen, check vital signs, and perform CPR. It also provides guidance for assessing responsiveness in adults and children, performing chest compressions, and reassessing the patient over time. Emergency medications that may be needed are also listed. The overall approach is to stay calm, follow the DRS-ABC protocol, and seek immediate emergency assistance.
