Abstract: A manikin with a disposable lung is used as a tool for teaching cardio-pulmonary resuscitation (CPR). The manikin includes a head, chest, disposable lung, and compression device. The head includes a "mouth" opening to receive air blown into it by a user, and the chest is removably connected to the head. The disposable lung is removably connected to the head in communication with the mouth opening. The compression device preferably is a resilient dowel like member which extends vertically through the manikin chest, having a stop which positively prevents resilient compression of more than a certain amount.
