  The Alveolar Stress Index is an under explored tool, promising and may help to prevent the deleterious effects of mechanical ventilation. The aim of this study was to describe the importance of Alveolar Stress Index tool, as well as aspects in ventilatory support. This tool evaluates the pressure-volume loop, which, although measures the pulmonary mechanical stress, it does not consider the heterogeneity of the respiratory system. The Alveolar Stress Index, checked in screen monitor of mechanical ventilation equipments, facilitates the detection of alveolar collapse zones (alveolar stress index <0.9) or overdistension (alveolar stress index >1.1) of lung areas. If the index value indicates alveolar collapse (atelectrauma=pulmonary lesion caused by the cyclic opening and closing of alveolar units and distal airways), it is recommended to increase the PEEP (Positi..
