This document provides guidelines for performing basic cardiac life support (BCLS) for infants and children. It outlines the steps to take which include checking for responsiveness and safety, opening the airway, giving rescue breaths, checking for a pulse and administering chest compressions if needed. For infants less than 1 year old, compressions are given using two fingers placed below the nipple line at a rate of 100 per minute. For children 1-7 years, compressions are given with one hand using the heel placed above the nipple line at a rate of 80-100 per minute. Rescue breaths are given at a rate of once every 3 seconds for infants and once every 4 seconds for children.
