The spatial distribution of pulmonary blood flow is increasingly heterogeneous as
progressively smaller lung regions are examined. To determine the extent of perfusion …

Both regional ventilation and regional perfusion demonstrate progressive increases in
heterogeneity as the resolution of measurement is improved. Because the efficiency of …

To determine whether vasoregulation is an important cause of pulmonary perfusion
heterogeneity, we measured regional blood flow and gas exchange before and after giving …

Endotoxin increases ventilation-to-perfusion ratio (V˙ a/Q˙) heterogeneity in the lung, but the
precise changes in alveolar ventilation (V˙ a) and perfusion that lead toV˙ a/Q˙ heterogeneity …
