Blood of a good tracing—four and a half hours after bleeding. Ancesthetics. — Marshall (see Cannon, 1917,p. 69) insists on the necessity of avoiding anything 72 INTRAVENOUS INJECTION like asphyxia, and points out the great value, forthis reason, of nitrous oxide and oxygen. In ex-periments on cats, I have found it difficult to main-tain anaesthesia with ether without more or lessdarkening of the blood, however carefully the etheris administered. Rebreathing Expired Air has been recom-. Fig. 26.—Rebreathing Expired Air. Cat under urethane. a. Started rebreathing by attachment of a wide tube, 166 cm. long, to tracheal canula. (Bicarbonate reserve = 54.) b. Tube off after twenty-three minutes. c. Tube on. d. Tube off again after twenty minutes. e. Forty-five minutes later. (Bicarbonate reserve = 35.) f.

As we have seen, IN WOUND SHOCK 73 there may be some advantage in adding a smallquantity of carbon dioxide to the air a number of experiments made by Cannon andmyself showed that expired air itself is very dele-terious, no doubt because of its deficiency in oxygen(see Fig. 26). If, however, carbon dioxide is used,
