An inexpensive take-home training aid for practicing human cardiopulmonary resuscitation (CPR) is contained in a non-humanoid shaped housing. When placed in a prominent location in the home, such as a child's room, the CPR training aid reminds users of the CPR sills they have learned and encourages them to practice with the training aid. The internal mechanism consists of a simulated airway, a compression mechanism, a compression feedback mechanism, a metronome, a breast plate and back plate with simulated anatomical landmarks, and / or an external landmark for identifying the proper location for placing a hand, hands, or fingers on the chest. Voice prompts on the steps of CPR and / or actual CPR performance may also be included. The chest plate and back plate are connected by one or more telescoping posts and a resistance device is between the two plates to simulate the resistance of a human chest to compression. The internal mechanism can be placed in a variety of non-humanoid containers such as a child's teddy bear or other stuffed toy. A CPR student can use the toy or other non-humanoid container to practice CPR during a CPR class and then later at home.
