Not illustrated. 1899 edition. Excerpt: ... CHAPTER XIX. HYPEEOXYGENATION OF THE BLOOD--DYSPNOEA. Hyperoxygenation of the Blood.--In previous chapters I have shown how widespread and complex are the effects of the respiratory movements on the organism, and how profoundly therefore it may be influenced by respiratory exercises. One important effect of such exercises has yet to be mentioned--i.e., their influence upon blood-oxygenation and upon the elimination of respiration excreta. By means of deep breaths we can produce a hyperoxygenation of the blood, and we can further the elimination of C02, and of the solid organic substances which are normally given off from the lungs, as well as of certain volatile toxines, and this without increasing in a notable degree the work done by the organism. It is probable that much of the good derived from respiratory exercises is referable to the changes thus brought about in the blood. That the brain is profoundly affected by deep breaths is shown by their tendency to cause giddiness, and it is not a little remarkable that this tendency wears off in those who practise deep breathing regularly, proving that it must produce a lasting effect upon the organism. Some of these effects have been studied by W. Marcet, and I will now epitomize his observations. The time during which an individual can sustain a voluntary muscle-contraction is determined by the endurance of the cerebral centres engaged in the act of volition rather than by that of the muscles themselves. Directly these centres are exhausted the muscle-contraction gives way. This act of volition entails a considerable absorption of oxygen by the centres engaged in it, and the more the quantity of oxygen available for absorption, the longer can the voluntary effort be made without...
