First aid is care given to someone before a paramedic arrives so for example.. If you and your friend are out on the trails on atvs and your friend wrecks his/her dirt bike and you are miles from the nearest help what would you do? without first aid your friend could die he/ she has a large deep gash in their thigh. It is bleeding bad and applying pressure isn't helping stop it. You remember something from first aid class that may help but your friend could lose their leg and is very scared. so you would try to calm him/her down reassure them and,then you apply a tourniquet to stop the bleeding. now you take your friend to the nearest help. You just saved your friends life but, if you didn't know first aid he/she could've died by the time a paramedic made it to where you were. That is why is important to know. that is what we were taught in my class it worked we all passed and knew how to apply first aid. hope this helped. :)
