Fig. 1From: Prone position ameliorates lung elastance and increases functional residual capacity independently from lung recruitmentPressure–volume curves of respiratory system, chest wall and lung in supine and prone positions. Mean respiratory system (Rs; circles), chest wall (Cw; triangles) and lung (squares) pressure–volume curves in supine (black) and prone (white) positions. Starting from functional residual capacity (FRC; volume = 0 ml), volume was inflated in 100-ml aliquots. After 5 s, the corresponding airway, oesophageal or transpulmonary pressure was recorded. Each symbol represents the mean value (n = 10), and standard deviations are not shown for clarityBack to article page
