Not illustrated. 1893 Excerpt: ...with inhibition of inspiration. Cheyne-Stokes' respiration; a pathological condition in which breathing is periodic, a pause of to $ of a minute being followed by an ascending and descending "staircase" of respirations. A somewhat similar form of respiration can be produced in animals by dividing the medulla transversely. Division of the vagi removes the periodicity, irregular spasms taking its place. Hibernating animals take a deep breath, followed by shallow breaths and then a pause. It appears likely, therefore, that Cltei/ne-Stokes' respiration depends upon the absence of controlling impulses which normally descend from above. The experiments upon animals throw no light upon the ascending staircase. Sherrington.--" Note on Cheyne-Stokes' Breathing in the Frog," Jour, of Phys., vol. xii. p. 278. Mann.--" A Contribution to the Study of Cheyne-Stokes' Breathing," Brain, vol. xiii. p. 178, 1890. EFFECT UPON THE CIRCULATION. Ill Problems in respiration can be solved if three things are borne in mind: --1. Fresh air contains 21 /o of 02, although about 6 or 7 /0 is sufficient to allow of respiration. On the other hand, if C02 accumulates in alveolar air to the amount of about 8 /o, its further exit from the blood becomes impossible. In a confined space, therefore, even though it contain nothing but oxygen to start with, death occurs from accumulation of C02. 2. Carbonic acid is a narcotic poison. Hence the violent convulsions produced by deficiency of oxygen are not seen when the blood is saturated with carbonic acid. This is the condition in fatal pulmonary disease. A. In a small space an animal dies in convulsions because all the oxygen in its blood is used up. B. In a large space full of air it suffers narcosis. C. In a ...
