All first aid classes, including free ones, will cover basic first aid procedures for treating a range of injuries, such as burns, choking, poisoning, head injuries, wounds, and bone fractures. Both in-person and online courses will teach individuals these first aid procedures. Many will also offer American Red Cross or American Heart Association first aid training to complete the class. In addition, many courses will teach child CPR, CPR for infants, and instructions for first responders.
