A medical training device with an improved clam shell type torso arrangement. An improved two-piece tiltable head feature, including mechanical mounting structure for secure attachment of an improved lung bag or face shield. The head also includes an improved nose feature to provide a more realistic representation of nasal cartilage, and an improved neck assembly. Additionally, an electro-mechanical indicator device is provided to show real time feedback of the CPR compression rate being administered by a student on the training manikin of the present application. The feedback by the device may be provided preferably by visual indicators, but may also have, or alternatively have, audio indicators or signals, such as words or sounds, to indicate whether or not the student is compressing within the preferred rate range, and/or the degree of variance in the student's compression sequences.
