This paper explores the rationale for why classroom teachers should be certified in cardiopulmonary resuscitation and pediatric first aid. It begins by introducing a scenario of two fatal tragedies in a school setting. It also examines a study done of teachers and school aides in inclusive classrooms and their concerns about health and safety issues. The paper touches upon the history of cardiopulmonary resuscitation (CPR), legal concerns, the mechanics of CPR, and a review of potentially fatal medical emergencies that could occur in an ordinary classroom setting. These emergencies include asthma, diabetes, seizure disorders, cardiac arrest, and severe allergic reactions. The paper discusses basic pediatric first aid, explaining that it should include, but not be limited to, a variety of potential emergencies. Finally, the paper recommends that all those who are directly responsible for the care and safety of children in schools or child-care settings should be certified in pediatric first aid (including CPR). Teachers should be recertified every 2 years. There should be clearly defined emergency procedures posted at visible locations throughout the school. (Contains 12 references.) (SM)
