Advanced functionalities of medical simulation tools can be used in the improvement of medical personnel skills. This applies in particular to complicated clinical situations involving patients in serious or life-threatening condition. Difficult and rare clinical cases can be the background for the preparation of simulation scenarios. Performing them in practice and discussing during the debriefing session allows to prepare doctors to make similar procedures in a real clinical environment. The method of problem-based and case-based learning is especially valuable. It allows to actively participate in the didactic process, focusing attention on a given issue in a holistic approach. The knowledge of the rules of conduct and the practical ability to act in such events increases the safety of treated patients. The simulation based case learning method can also be used to train medical personnel of the Polish Armed Forces.
