In another embodiment, the cardiopulmonary resuscitation device is structured for use on an infant-sized human. In this embodiment, the device includes a pair of legs extending through the case, the support structure permitting the case to be positioned on the chest of an infant-sized human wherein the case is useable to perform cardiopulmonary resuscitation on the infant-sized human by repeated press-release movements using a finger pad disposed on the case.
