Br. J. Haukes Apparatus for Artificial Kespi-ration. This apparatus assists the mechanism ofrespiration ; artificially promotes the comple-tion of inspiration by the introduction ofcompressed air, and facilitates expiration bythe introduction of rarefied air. Besides, it can conveniently be employedas an inhaling apparatus, as the air whichis to be inhaled can be medicated, and thusthe inhalation facilitated by the mechanicaleffect of the apparatus. The apparatus consists of a cylindrical tin. vessel [A), which is divided into two equalchambers, communicating from below; oneof these chambers (the real air chamber B)is slightly higher, closed from above, uponwhich is attached a bellows (or air pump D);on each side of this bellows is a tube (&larger one), leading to the mask (e); theother (smaller one, e), connects with thebellows. AVhen the vessel is filled with wa-ter, according to direction, air can either becompressed or rarefied at will. The mask,which is made of brass, in shape of a flathalf shell, fits closely around the mouth andnose, and permits the patient to breathe fromthe apparatus or the atmosphere by meansof an opening, at will. The most frequentapplication, thus far, of the apparatus, hasbeen found in asthma, emphysema, and asa prophylactic in phthisis pulmonalis.—From a pamphlet hy Dr. J. HauJce, en-titled Ein Apparat fur Kunstliche Respira-tion und dessen Anwendung zu , 1873. Dec 6, 1873.] Notes and Comm
