@gethelpwithproctoredexam: Cardiac arrest is a sudden, life-threatening cessation of heart function that halts systemic circulation. Without immediate intervention, brain injury begins within 4–6 minutes, and survival rates drop by 7–10% for every minute lost. The condition is diagnosed by a lack of pulse and responsiveness. Management follows a prioritized ladder: Basic Life Support (BLS) focusing on high-quality chest compressions (100–120/min) and Advanced Life Support (ACLS) involving defibrillation for shockable rhythms like VF/VT, and drug administration (Adrenaline). Reversing the arrest requires identifying the "Hs & Ts", ranging from Hypoxia and Hypovolemia to Toxins and Tension Pneumothorax. Successful resuscitation leads to Post-Care, where maintaining oxygenation and blood pressure is vital to prevent multi-organ failure or permanent hypoxic brain damage. #cardiaccare #nerves #studynotes #nursingstudent #students
