Variability of vital signs in simulations with mannequin in education of bioengineers

We are using life-size mannequins within an education subjects, e.g. “Medical devices” for a demonstration of basic principles of modern clinical devices such as mechanical lung ventilator. Limitation of many simulators is uniformity of its outputs for same input parameters. This paper describes variability of the vital signs of the mannequin when the same scenario was used for different base patients available at human patient simulator.
