Abstract: In a system and a method of testing a person in the performance of cardiopulmonary resuscitation and for evaluating training exercises therein, a training device simulating a patient includes sensors for detecting various resuscitation procedures performed thereon. Parameter signals from the sensors are fed to a computer including a series of counters, a timing means and various memories, for analyzing the parameter signals and assessing whether the corresponding operations have been correctly or incorrectly performed. The values processed by the computer are then displayed on a display providing a clear moving representation of the procedures performed on the training device, the representation taking place in real time on the basis of corresponding signals from the timing means, whereby, by viewing the display, the trainee operator can directly check and if appropriate correct the resuscitation procedures he is performing.
