Deflation flow–volume curves (DFVCs) in intubated infants. (A) Term newborn without lung disease. The outer curves are superimposed DFVCs obtained with inflating pressure of +40 cm H2O and deflating pressure of −40 cm H2O; the middle curve is a passive flow–volume curve after the lungs were inflated with a pressure of +40 cm H2O; the small inner curve is a passive flow–volume curve from a standard pressure of +10 cm H2O and is used to calculate respiratory system compliance and resistance. (B and C) DFVCs from newborns with RDS and MAS. Note the tall and narrow configuration of the curves that illustrate the very high airway conductance seen in both conditions. MAS = meconium aspiration syndrome; RDS = respiratory distress syndrome.
