    acids are present in the blood stream, as in acidosis, an elimination of carbonic acid to compensate for the presence of these stronger acids automatically occurs, and the concentration of carbonic acid in the blood and tissues is thereby reduced. As this reduction is directly proportional to the amount of foreign acids present, the concentration of carbonic acid in the blood furnishes an excellent quantitative guide to the severity of the acidosis, and a number of methods for the measurement of acidosis depend on this principle. One of these methods consists of measurement of the concentra¬ tion of carbon dioxide in the lung alveolar air. Because this air is constantly in intimate contact with the blood circulating through the lungs, the concentration of carbonic acid in this air is the same as in the blood, and therefore may be taken as a measure of the concentration in the blood. Within the last decade, however, the method devised by Van Slyke1 for measuring the carbon dioxide concentration of the blood, has come into common usage. Because this method is practically direct and does not require cooperation on the part of the patient, as is the case in obtaining samples of alveolar air, it has now, in this country at least, entirely superseded the other methods. ACIDOSIS The term acidosis is really a misnomer, because it conveys the idea of an acid condition of the Chapter XI.
