Based on current American Heart Association Guidelines for chest compression and rhythm, Saving Lives! helps players practice their foundational CPR and basic life support skillsets by administering CPR to a patient in a simulated emergency scenario. Players will internalize the compression rate and proper procedure for CPR, receiving contextualized, just-in-time feedback as patient status changes based on their performance. Players will also gain experience using an automated external defibrillator (AED) to resuscitate unresponsive patients.
