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 an experimental setup for a test-bed to evaluate the actual vented masks on the market, and in the future to evaluate new concepts to be developed and proposed. As face reference, in this stage, it's used a dummy head with a not deformable skin, reducing in such way the variables related to the skin and all organs behind the skin and respective interfaces. As major unknowns we have pre-selected the maximum contact pressure on the skin by the mask, the headgear traction force in each mask anchorage point, instantaneous relative pressure on the mask and instantaneous critical pressure areas on the mask-face interface. Several solutions are discussed in this work.
