From: Lung volumes and lung volume recruitment in ARDS: a comparison between supine and prone position
Variation in lung volumes in supine and prone positions. Clear triangles and clear rhombus are the resting lung volumes at ZEEP and at PEEP. Dark triangles and dark rhombus represent end-inspiratory lung volumes and end-inspiratory lung pressure (Pplat) at ZEEP and at PEEP. PEEP, positive end-expiratory pressure; ZEEP, zero end-expiratory pressure. Data are shown as mean and SD
