Free online first aid classes will teach participants the basics of treating accidental injuries such as broken bones, seizures, burns, wounds, head injuries, eye injuries, poisoning, and choking or airway obstruction. In addition, many classes will cover basic CPR and techniques like child CPR or CPR for infants. However, it is essential to remember that free first aid or CPR training classes provide instruction only and will not provide certification upon completion. For individuals who wish to obtain official first aid and CRP certification, a proper course, like a Red Cross certification class with a CPR and first aid exam, is required.
