From: Lung volumes and lung volume recruitment in ARDS: a comparison between supine and prone position
Variation of lung volumes with the change of position. a Comparison of different values of functional residual capacity. b Comparison of EELV and Vrec in supine position and prone position. EELV, end-expiratory lung volume; Vrec, PEEP-induced lung volume recruitment; Vt, tidal volume. Data are presented in mean (ml) and SD. *According to the equation described by Ibañez and Raurich [30]
