This document provides an overview of cardio pulmonary resuscitation (CPR) presented by Mr. Sudhir Khuntia. It defines CPR as a basic life support technique used to oxygenate the brain and heart until medical treatment can restore normal function. The goals of CPR are to promote circulation through chest compressions and maintain an open airway through breathing efforts. Proper CPR involves assessing for responsiveness, calling emergency services, performing chest compressions at a rate of 100 per minute combined with rescue breathing at a ratio of 30 compressions to 2 breaths.
