End-expiratory lung volume (EELV) in the acute respiratory distress syndrome (ARDS) patients and functional residual capacity (FRC) in the healthy subjects were measured by rebreathing of sulphur hexafluoride (SF6) and computed tomography (CT), respectively. Predicted normal FRC values are from [25]. |
