A CPR training assembly for instructing a person to perform CPR or choking rescue on an infant, a child or an adult includes a housing and an audio unit that is coupled to the housing. The audio unit emits audio outwardly from the housing to audibly alert a user. The audio unit stores data pertaining to audible instructions for performing CPR or choking rescue on infants, children and adults. A control unit is coupled to the housing and the control unit is electrically coupled to the audio unit to select the audible instructions for a respective one of the infants, children and adults. In this way the user can choose to receive audible instructions that correspond to whether an infant, a child or an adult needs CPR or choking rescue.
