Cardiac arrest

Cardiac arrest is an acute, life-threatening medical emergency characterized by the abrupt cessation of mechanical cardiac activity, leading to the immediate loss of effective systemic circulation It primarily affects the cardiovascular and central nervous systems, rapidly causing widespread tissue ischemia and end-organ hypoxia Clinically, affected individuals present with sudden unresponsiveness, absent or agonal respirations, and the lack of palpable central pulses Pathophysiologically, it is...

Cardiac arrest is an acute, life-threatening medical emergency characterized by the abrupt cessation of mechanical cardiac activity, leading to the immediate loss of effective systemic circulation Pathophysiologically, it is triggered by electrical dysfunction or mechanical failure of the heart, most commonly manifesting as ventricular fibrillation, pulseless ventricular tachycardia, pulseless electrical activity, or asystole

It primarily affects the cardiovascular and central nervous systems, rapidly causing widespread tissue ischemia and end-organ hypoxia Clinically, affected individuals present with sudden unresponsiveness, absent or agonal respirations, and the lack of palpable central pulses
