A series of experiments was carried out on 28 dogs in which the following aspects were investigated: in 9 dogs, the special configuration of acute lobar atelectasis; in 10 dogs, the pressure-volume characteristics of collapsed and non-collapsed diaphragmatic lobes; in 12 dogs, the wet-weight/dry-weight ratios of atelectatic contralateral lobes; in 6 dogs, the amount of blood sequestered in atelectatic diaphragmatic lobes was estimated. The relationships of an atelectic lobe closely resemble those described in man. Loss of apposition between visceral and parietal pleural surfaces was never observed. The W/D weight ratio of the collapsed lobe invariably was higher than that of the non-collapsed contralateral lobe indicating a slight increase in the volume of fluid in the atelectatic lobe. No pressure-volume differences were found between atelectatic and non-collapsed lobes.
对28只狗进行了一系列实验，研究了以下几个方面：9只狗研究急性大叶性肺不张的特殊形态；10只狗研究萎陷和未萎陷的膈叶的压力-容积特性；12只狗研究肺不张对侧肺叶的湿重/干重比；6只狗估计肺不张的膈叶中滞留的血量。肺不张肺叶的关系与人类描述的关系非常相似。从未观察到脏层和壁层胸膜表面之间的贴合丧失。萎陷肺叶的湿重/干重比始终高于未萎陷的对侧肺叶，表明肺不张肺叶中的液体量略有增加。肺不张肺叶和未萎陷肺叶之间未发现压力-容积差异。
