Find the best CPR and first aid lessons, classes and instructors at HeyKiki and learn how to administer CPR and first aid. First aid refers to provisional care for an illness or injury before more thorough medical treatment can be received. First aid can be performed by non-professional individuals trained in basic treatment and care for a variety of ailments, and are required for some vocations such as lifeguarding or babysitting. CPR, which stands for cardiopulmonary resuscitation, is a component of first aid, and is performed on patients with an open airway who have stopped breathing. Other forms of first aid include treating cuts and scrapes, head injuries, falls, choking victims, and broken bones. Online certification and training for CPR and first aid is available for those who cannot attend an in-person course.
