Analysis of airway pressures and flow during volume-controlled mechanicalventilation. The difference between peak or maximal pressure(Pmax) and plateau pressure (Pplat) defines theresistive pressure, whereas the difference between Pplat andpositive end-expiratory pressure (PEEP) defines the elastic pressure. Analysisof the airway pressure shape during the phase of constant flow inflation(removing initial and final parts) can be used to calculate the stress index(arrow).
