Flow mechanisms of the air-blood barrier
Fig 2
(a) Flow rate definitions across boundaries (b) Streamlines, velocity fields, and color-coded pressure field for: (b upper) the base set of parameters, BASE; (b lower) is BASE with pAG = 15 cmH2O PEEP.
Note that the horizontal axis is compressed for 0.1 ≤ X ≤ 0.9 and circumscribed with a blue rectangle. The bounding streamlines in yellow separate alveolar and capillary contributions to the end-exit flows at X=0 and X=1 which become available to lymphatics., (c) Flow calculations for Normal/Recovery including BASE, PEEP and zero absorption velocity, vab = 0. Note QAL = QA0 + QA1 and QcL = Qc0 + Qc1. See text for details.
