Basic Life Support is a comprehensive course meant to teach cardiopulmonary resuscitation (CPR) to the professionals in a team set up so that they build confidence to respond to emergencies.
This course teaches the important steps to perform a rapid assessment, perform Basic Life Support (BLS) skills, and perform rapid defibrillation including the use of an Automated External Defibrillator (AED). So it is necessary to get a BLS certification to fight emergencies.
