Image analysis measurement of alveolar stability. In vivo photomicrographs of the same microscopic field at (a) peak inspiration and (b) end expiration. Individual alveoli were outlined and the area at peak inspiration (I) and end expiration (E) was measured using image analysis software. Alveolar stability was assessed by the percentage change in the area of individual alveoli from I to E (%I – EΔ).
