It is well-known that pressure sores can be avoided. But what do we need? Human resources or technology or both. The aim or this work was to demonstrate that technological surfaces are quite useful, sometimes indispensable, although not to be left out culture of prevention and nursing support. The authors analyzed 5 different technological antidecubitus surfaces in comparison with standard foam mattresses, using a Com- puterized Pressure Imaging System (Xsensor®) to evaluate the pressure relief effectiveness and a Reflectance Oxygen Saturimeter to evaluate the perfusion of the skin areas subjected to pressure. Then they selected 3 critical patients with high risk of development of pressure ulcers and followed then for about 18 months after giving them 3 different mattresses that were chosen according with the patients’ assessment. The study is still in progress but, after more than 300 measurements, the authors have demonstrated that technological surfaces are very effective in prevention, that there is a significant improvement in terms of perfusion and that it is possible to achieve an important improvement of the pre-existing pressure sores.
