[Filtration-absorption functions of the lungs during changes in respiratory volume].
In anesthetized cats, within the range of intermittent transpulmonary pressure (from -8 to +8 mm Hg) no significant shifts of the filtration-absorption balance were revealed. At the transpulmonary pressure +14 mm Hg the capillary hydrostatic pressure increased by 30% and filtration prevailed over absorption. Similar changes could occur at +8 mm Hg in case the tone of the lung vessels was reduced with papaverin. Mechanisms of effect of the respiratory volume changes on the filtration-absorption balance in the lungs, are discussed.
