COLLATERAL RESPIRATION

Collateral Respiration Literature

During the course of some experimental work on the pathogenesis of obstructive pulmonary atelectasis we have noted a consistent occurrence of certain forms of behavior which suggests that the lobules composing single lobes of the lungs are connected collaterally with each other. Thus, after the bronchus of one lobule has been obstructed, that lobule appears to receive air from, and to give air ...

Collateral Pulmonary Respiration of Van Allen

process was impaired by inflammation.3,9 These observations were confirmed by means of gas analysis by Lindskog and Van Allen.A Collateral respiration was also demonstrated in relation to experimental segmental emphysema produced by valvular bronchial obstruction. Lobar emphysema followed valvular obstruction of lobar bronchi, but no emphysema resulted from this type of obstruction in the prima...

Collateral Respiration in the Normal and Diseased Lung *

Until 1930 the pulmonary lobule was generally considered to be anatomically and functionally an end structure, to which the only access of air lay in the direct bronchial route. All available anatomical data from such pioneer workers as Joseph Marshall Flint, Macklin, and William Snow Miller argued against the possibility of air passing collaterally from one pulmonary lobule to an adjacent one ...

Collateral Crises⇤

Short-term collateralized debt, private money, is efficient if agents are willing to lend without producing costly information about the collateral backing the debt. When the economy relies on such informationally-insensitive debt, firms with low quality collateral can borrow, generating a credit boom and an increase in output. Financial fragility is endogenous; it builds up over time as inform...
