“…In addition to the changes in the hydrostatic pressure, the effects of lung inflation on transmural pressure distribution may also have an effect. Kira & Hukushima () demonstrated that when the vascular transmural pressure was approximately 5 cmH 2 O, a low‐pressure condition, the pulmonary vasculature resistance increased as the lung stretched. However, when the vascular pressure was high (11 cmH 2 O), the transmural pressure in small vessels remained high and the vasculature cross‐sectional area remained large.…”

“…However, when the vascular pressure was high (11 cmH 2 O), the transmural pressure in small vessels remained high and the vasculature cross‐sectional area remained large. Therefore, in the high transmural pressure condition, the reduction in vasculature cross‐sectional area due to axial stretch was a lesser influence and the vasculature resistance was virtually unchanged (Kira & Hukushima, ). Pulmonary vessels with low transmural pressures are predominantly located in the gravitationally non‐dependent region, while the high transmural vessels are located in the gravitationally dependent region of the lung.…”
