Early intervention, quality of CPR and time to defibrillation improves survival rate after cardiopulmonary arrest. BLS is an important component of the chain of survival. The proper practice of BLS is an important part of a medical student’s training, but there is still no standard protocol and routine training incorporated in the medical undergraduate training in developing countries like India. Medical graduates, never having had any formal training in CPR or BLS, often face difficulty in emergency situations.
