1. A CPR training mannequin, comprising
a humanoid torso, the torso having a torso shell composed of a material having a degree of transparency and having sufficient material properties to withstand forces of simulated chest compressions; a humanoid head having a degree of transparency and pivotally connected to the torso and having a mouth opening connected to a ventilation tube forming a simulated airway; at least one resilient element; a base, the resilient element located between at least a top wall of the torso shell and the base, the resilient element resisting downward displacement of the top wall of the torso shell during simulated chest compressions; a simulated heart and simulated lungs arranged within the torso shell and visible through the top wall of the torso shell, the simulated heart and lungs including lights; a control; a ventilation sensor and a displacement sensor connected to the control, the ventilation sensor located in the ventilation tube and the displacement sensor measuring movement of the top wall of the torso shell with respect to the base; a switch within a flexible nose of the head, the switch being signal-connected to the control to indicate the nose is properly pinched closed; wherein when the head is correctly tilted to open the simulated airway, the control issues an initial illumination command to light the lung lights; wherein pinching of the nose triggers the switch to indicate the nose is properly pinched closed; and, wherein when the head is correctly tilted open and the nose is properly pinched closed the control compares ventilation from the ventilation sensor with acceptable CPR values and issues a second illumination command to further light the lung lights if the ventilation is satisfactory with the acceptable CPR values; and, wherein the control compares displacement from the displacement sensor with acceptable CPR values, and issues an illumination command to light the heart lights if the displacement is satisfactory with acceptable CPR values. |
