Michigan schools will have to provide CPR instruction under legislation signed by Lieutenant Governor Brian Calley. The law enacted this week takes effect in the next academic year. The measure requires that schools provide instruction in CPR and the use of defibrillators at least one time between grades 7 and 12. The instruction can be for hands-only CPR, a simpler type of training that does not require certification or mouth-to-mouth resuscitation. To meet the requirement, schools can incorporate the training into an existing health class that students must take to graduate. Health advocates say the law is a simple way to have more CPR-trained lifesavers in Michigan. Calley signed the bill because Governor Rick Snyder is vacationing out of state.
