More than 130.000 CardioPulmonary Bypass and 16.000 ExtraCorporeal Membrane Oxygenation are performed yearly by pefusionists. These extracorporeal circulation (ECC) techniques are used to replace or complement the function of the heart and the lungs, in severe cardiac or respiratory failure. Most accidents related to ECC are caused by human errors and failures at facing critical incidents. Intensive training is essential to improve safety. However, physical simulators are expensive, require maintenance and do not allow massive student practice.
