Lung model study, protocol II. ΔLeak (difference between Leak_conv and Leak_pause) is shown at constant inspiratory flow as a function of respiratory system mechanics in a simulated model of constant cross-sectional area around the endotracheal tube. R, model airway resistance (cmH₂O/litre per second); C, model compliance (ml/cmH₂O). *, Significantly different from the corresponding value at C = 100 ml/cmH₂O. ⁺, Significantly different from the corresponding value at C = 50 ml/cmH₂O.
