The plateau pressure is the pressure applied (in positive pressure ventilation) to the small airways and alveoli. It is believed that control of the plateau pressure is important, as excessive stretch of alveoli has been implicated as the cause of ventilator induced lung injury.
Originally Answered: What is the difference between pressure and stress? Pressure is often used with fluids (gases or liquids), whereas stress is more often used with solids. One major difference is that pressure only acts perpendicular to a surface, whereas stress can also be parallel to a surface as well as perpendicular to it.
