Abstract (EN): The use of vented face masks is a common method in persons with respiratory failure. The interface between the mask and the face is associated with failure caused by several factors, as the appearance of cutaneous wounds or ulcers, or air leak by defective mask sealing in cushion-skin contact. The goal of this work is to prepare and validate a methodology based on FEM to evaluate in a virtual environment the interface between the vented mask cushion and the skin, taking as reverence the same system developed in-vitro. The in-vitro model was virtualized and meshed. Characteristics of materials and interfaces have been defined according to the literature and in-house experiments. The results for a particular pair of dummy head with the one correspondent vented mask are presented.
