which collectively may be designated as mechanical methods of artificial respiration. Fell (1887)- was probably the first one to use successfully in human beings (.in cases of poisoning; the method usually employed in the physiological laboratories (trache- otomy and bellows). Later Fell recommended the use of a mask in place of a tracheotomy tube. Northrup (1896) advocated the use of a modified O'Dwyer tube connected buy viagra tips with bellows (Fell-O'Dwyer apparatus). At about the same time several French investigators attempted to devise methods of arti- ficial respiration by the aid of mechanical means, among whom Tuffier and Hallion, and Doyen de- serve to be especially mentioned. Doyen's appar- atus consisted of -'duplex" bellows (for insufflation and suction) attached to an intralaryngeal cannula. R. Matas ( 1902)' constructed an apparatus in which a modified O'Dwyer tube was connected with buy viagra tips an automatically acting pump. The pump contained originally two independent metal cylinders for in- spiration and aspiration. However, order viagra australia the first ex- periment made on a order viagra australia dog convinced Matas that the suction force, exercised by the aspirating cylinder, does damage to the lungs, and he eliminated that part from his apparatus." In his efforts to apply the method of intubation to all cavities and order viagra australia tubes of the body Franz Kuhn became also active (.in Ger- many) in introducing the method of intralaryngeal intubation as a means of resuscitation. To the foregoing the statement is to be added that, as is generally known, in the last seven or eight years various efforts have been made in this country to introduce mechanical resuscitating ma- chines. But I wish to point out order viagra australia that most of these efforts are to be distinguished from all foregoing activities by one deplorable characteristic : while the activities in the foregoing periods were stimulated practically solely by humanitarian and scientific purposes, nearly all the apparatus and machines which are being introduced at present, and which receive a lesser or greater unscientific publicity, have one unpleasant feature in common, namely, the plain and unveiled commercialism which is evidently the *Courtois seems to have been the first buy viagra tips one who as early as 1790 (Jour, de meet, cliir. et pharm., Paris, LXXXII, p. 361) buy viagra tips introduced the duplex metal cylinder as a means of inducing artificial respiration under the designation of "pompe apodpinque" (quoted from a pamphlet by Dr. William Harrison, Pneumatry papers No. 1, Detroit, Mich., 1916). According to Harrison. Poe's Artificial Respirator, which is now extensively advertised by the Life Saving Devices Company under the name Lung-motor, is identical with Courtois' "pompe apodpinque." Harrison himself is now intro- ducing an apparatus under the name of "Pneumatizer" which, according to the inventor, is free from the short- comings of the Lungmotor. MEDICAL RECORD. [July 7, 1917 sole motive for their construction. Their introduc- tion to the public is accomplished by the usual meth- ods by which commercial products try to make head- way, namely, by a more or less loud advertising. It is rather a sad chapter in the history of resuscita- tion ; but I do not intend to dwell upon its details. II. Criteria for the Efficiency of the Methods of Treatment. — What evidence do we possess that cer- tain methods which are employed for resuscitation are really efficient? As far as I know there are at present only three criteria which may serve as guides for buy viagra tips our judgment. Statistics. For more than 100 years the char- acter of the evidence was exclusively of a statistical nature, namely, that if a certain method, employed for resuscitation, had a high percentage of suc- cesses to its credit, it was considered as a proof that buy viagra tips the method was indeed a useful one. But the statis- order viagra australia tics given in the above mentioned articles of Keith demonstrate at a glance the fallacies contained in this method. For instance, for many order viagra australia years "fumiga- tion" (.introduction of tobacco into the large bowel) seemed to be a most reliable method. Later, how- ever, on the contrary, it was forbidden. At another period when only warmth and friction were em- ployed for resuscitation, these procedures, judging from the statistical data, seemed to have given the best results. Then the various methods of artificial respiration had, as seen above, their "ups and downs" in the history of resuscitation. It is evident that the value of the reports of successful treatment of the apparently dead varied greatly with the character and judgment of the reporters and with the nature of a great many circumstances which were not taken into consideration. Uncritical, statistical data, as is now order viagra australia generally conceded, have not only no value, but are very often decidedly mis- leading. As to the statistical data collected for transparently unlaudable purposes, with which re- grettably all branches of medicine in our country is overwhelmed, the term "misleading" is surely in- sufficient for their characterization. Respiratory Volume. — "Science is measurement." quotes Schafer in his Harvey Lecture. 5 The crite- rion which played and still plays a considerable role in the estimation of the value of the methods of manual artificial respiration consists in measuring order viagra australia the volume of the air inspired and expired into a spirometer. This method was, I believe, introduced by Schafer. At first he experimented on drowned dogs; but these experiments order viagra australia gave no satisfactory results, because drowned dogs recover often without artificial respiration, sometimes even after having been for five minutes under water, that is, without any respiration whatsoever. On the other hand, if the heart of drowned animals stops beating, as a rule none of the manual methods of artificial res- piration, no matter how early begun, is capable of resuscitating them. The experiments with meas- uring the volume order viagra australia of air on dead human bodies also gave no satisfactory results on account of the vari-
