Summary of morphometric measurements (mean ± SD) made in lung tissue sections from preterm lambs managed by intermittent mandatory ventilation (IMV; white bars) or high-frequency nasal ventilation (HFNV; black bars) (n=4/group). Radial alveolar count (panel a) and volume density of secondary septa (panel b) were significantly greater, whereas distal airspace wall thickness (panel c) was significantly narrower, in the HFNV group than in the IMV group. * different from the corresponding IMV group by unpaired t-test (p<0.05).
