From: Optimizing positive end-expiratory pressure by oscillatory mechanics minimizes tidal recruitment and distension: an experimental study in a lavage model of lung injury

Figure 1

Left panel: Respiratory system resistance (Rrs), oscillatory elastance (E X5 , the inverse of compliance), percentage volume of aerated (VtissA%, blue), poorly aerated (VtissPA%, green) and nonaerated (VtissNA%, red) tissue at end-expiration (closed symbols) and at end-inspiration (open symbols) for one representative animal. Squared symbols are used for incremental positive end-expiratory pressure (PEEP), circles for decremental. Right panel: a representative computed tomography (CT) slice (selected approximately 1 cm above the diaphragmatic dome) of the same animal at end-expiration (EE) and at end-inspiration (EI), at the different PEEP levels during the incremental (UP) and decremental (D) PEEP trial. Colour code for regions as above.
