In the Heartsaver CPR/First Aid course you'll learn when CPR is needed, how to give CPR to an adult, child and infant, and how to use an AED. CPR stands for cardiopulmonary resuscitation. It consists of pushing on the chest (compressions) and giving breaths. First Aid is the immediate care that you give someone with an illness or injury before someone with more advanced training arrives and takes over. First Aid may help someone recover more completely or more quickly and may mean the difference between life and death.
