In introducing to the Profession this new preparation, a compound of Oxygen and Nitro- gen we do not claim to have discovered any new virtues in a therapeutic agent which has been for some years on trial and which has demon- strated, to all who have made use of it, its great efficiency in conditions calling for its administra- tion. It has seemed to us, in view of the fact that the market has been over supplied with preparations of this gas, many of which were unstable com- pounds, liable to deteriorate between the time of production and the moment of use, and many too being of variable strength, and not infrequently containing very different propoitions of Oxygen and atmospheric air, retailed at extravagant prices, that there was open to us a field for the introduc- tion of an Oxygen compound which should be always the same strength, always free from adul- terations and dilution, and always containing exactly the proportions of Oxygen and Nitrogen which have been found by skillful practitioners to be the very best for the accomplishment of the desired ends. The therapeutic value of Oxygen, in the form supplied from the great laboratory of Nature* namely, fresh air, is well understood. Why do we send our invalids, convalescents and persons of delicate health to the plains of Texas, the heights of the Rocky Mountains, the wooded hills of the Adirondacks? Is it not that in these localities they may breathe an atmosphere free from impur- ity, and abounding in that life-giving and disease- destroying agent Oxygen ? Following on the line of thought suggested by this practice, a practice as old as the history of medicine itself, the idea is naturally conceived that Oxygen in some form will be of the greatest benefit if it can be supplied in a shape suitable to its administration at the bedside and in the physician’s office to those whose strength, business occupation or means do not permit them to journey to the lands where this vitalizing agent may be found in greatest quan- tities. Oxygen in its pure state is too powerful a sub- stance to be used to any extent in medicine. To accomplish its best results it must be diluted with some other substance. This being the case, what is to be preferred to Nitrogen, a substance selected by Nature herself as a medium for the dilution of a gas too powerful to be allowed to come in con- tact in its pure state with organic matter. No secret is made of the formula of this well recog- nized curative agent. After careful experiment it has been found that Oxygen, combined with Nitro- gen monoxide in the proportions of two atoms of the former with one of the latter, produces a com- pound in part a mechanical mixture, and in part a true chemical union of its component parts, which has been found to possess singularly remarkable powers in controlling many disease processes affecting many different organs of the body. As referred to in the opening sentences of this brief statement there is ground for belief that many preparations now on sale are largely diluted, and not at all what their makers claim them to be. In order to supply a remedy constant in its composi- tion, and which may therefore be expected to be constant in its operation, the manufacturers of this preparation have spared no time and patient investigation, and believe that with their improved methods of manufacture, and careful supervision by competent chemists, they have succeeded in placing upon the market a compound of Oxygen and Nitrogen which will meet the wants of the practising physician and which will be absolutely reliable, leaving no margin of doubt for the possi- bility of a failure in its therapeutic action due to careless methods of manufacture. Owing to these same improved methods of pro- duction, reference to the price lists annexed will show that this company is prepared to supply this superior article at a price less extravagant and more within the reach of all, rich and poor alike. THERAPEUTIC ACTION OF OXYGEN. With a proper realization of the important share Oxygen has in the organism of animals and plants, it seems incredible that physicians and surgeons have until recently failed to perceive the immense possibilities in its use as a therapeutic agent in many forms of disease. The necessity of a constant supply of Oxygen for purposes of respiration is well understood, and this fact has been dwelt upon and impressed upon all, by those who have made a study of the laws of hygiene. This is well as far as it goes, but it remains for a few earnest workers to materialize and proclaim its advantages in the treatment of disease. It is needless to recapitulate the function of Oxygen in the various chemical processes going on in the human economy. These are well understood by all, and it is equally well understood that a diminu- tion in the proper supply of Oxygen to the organ- ism, produces results far reaching and destructive, and that its total deprivation insures speedy death to animal life. This being the case, it is irrational to suppose that certain conditions characterized by mal-nutrition, lack of proper assimilation and gen- eral lack of vitality and health, will be not greatly benefited by the exhibition of this agent in a form suitable for ready introduction into the system. This fact seems to be so well established that argument is unnecessary to convince all of its truth. It is true objections may be raised against the inhalation of Oxygen. Why, it is said, give Oxy- gen artificially prepared when we find it, especially in the country under normal conditions, and in a mixture appropriate to our needs ? Truly it would be desirable if we could put all our invalids and convalescents under such happy surroundings. This, however, cannot be done, and admitting it we do not know but that, if the thorough oxygen- ation of the blood gives such therapeutic results, an artificially increased arterialization wouldnotput us in condition to more easily resist certain disease- producing influences. Again it may be said that breathing air too highly oxygenated may be harm- ful to the system. This is true, and it is for this reason that in the preparation of this Oxygen com- pound such care has been taken to present it in a form incapable of doing injury to the most sensi- tive animal structure. Another property of Oxygen is its well known antiseptic power ; disease germs cease to be active in an atmosphere composed entirely of Oxygen, and an abundance of this agent tends to delay and destroy their growth and reproduction. Hence the value of Oxygen in diseases of the lungs, which are now known to be produced by the multiplica- tion of disease germs in these organs. In addition to this sphere of action, an inhalation of the Oxygen compound under moderate pressure tends to open up air cells which have become closed, owing to relaxation and partial adhesion of their walls. This combined with certain gymnastic exer- cises calculated to expand the chest, is of the greatest service in warding off incipient phthisis. Enough has been said to indicate the general benefit to be derived from the administration of the Oxygen compound in the treatment of disease. A brief statement of some of the special con- ditions in which it is indicated, with a few of the beneficial results will be in order. Bronchial Disorders. In cases of acute bronchitis, particularly of the capillary variety, this remedy will be found of service. Especially is this the case in old persons with weak-acting hearts, where owing to insuffi- cient oxygenation of the blood, cyanosis and dyspnoea are prominent features. In these cases it acts like magic, a few inhalations give a sense of relief, which by repetition can be renewed, and which will do much to tide the patient over the critical stage of the disease. The relief is great, and often distressing orthopnoea is entirely re- lieved, and comfort and quiet rest secured. This alone would be sufficient excuse for retaining the Oxygen compound in the list of remedial agents. Emphysema of the Lungs. This disease in its pronounced form is often characterized by attacks of bronchial asthma. The lungs become distended during the attacks, but owing to the lack of elasticity in the walls of the air vesicles, air cannot be expelled, and as new air cannot be taken in, that which is already there soon loses its oxygen, and becomes unfit for respiration. This accounts for the great oppres- sion and cyanosis characteristic of these attacks. Mechanically, the lungs are prevented from prop- erly supplying the blood with oxygen. Here it is that the inhalation of the oxygen compound by supplying a quantity of oxygen greater than that normally existing in the air vesicles, acts like magic in relieving the distressing symptoms and is a remedy unexcelled. Heart Disease, Organic Lesions. A great field for the administration of oxygen, and one .in which it has won many laurels, is the condition of pulmonary engorgement and oedema so common in the later stages of valvular disease of the heart, that organ by its gradual giving out, allowing the venous system to become overloaded, with consequent stasis and congestion of the pulmonary circulation resulting in accumulation of serum in the air vesicles themselves. This of course, interferes by its very presence with the entrance of a proper supply of air into the air- vesicles and by infiltration of thin walls destroys their elasticity thus preventing the expulsion of air which has already been deprived of its oxygen and become overloaded with carbonic acid. In these cases the oxygen gas will do wonders, sup- plying as it does, at the very point where it is most needed, oxygen in a state to be easily and quickly taken up by the blood and carried as a vitalizing agent to every part of the debilitated organism. A single case will illustrate this. Mrs. S—, aged 55. Mitral insufficiency of long standing. From over exertion and anxiety seized with palpitation and irregular action of the heart. Examination showed that the heart was greatly dilated, and that its action was very feeble. Temperature sub-normal, strength diminished, extremities cold, cyanosis very marked. Inhala- tions of oxygen were ordered every two hours in addition to the proper remedies. Each inhalation gave relief, respiration became easier, heart action stronger and cyanosis disappeared. In a few days the acute dilatation of the heart subsided and patient shortly after returned to her normal con- dition, or that which had been normal for several years previous. This is only one of a number of such cases in the writer's experience. Fatty Degeneration of the Heart. In this condition, essentially a giving out pro- cess, we find the same conditions of the respiratory organs that occur in cases of valvular lesions of the heart. The lungs are overloaded with blood, the amount of air in them is necessarily dimin- ished, and the normal interchange of oxygen and carbonic acid is to a great extent interfered with. Here again the administration of the Oxygen com- pound is indicated and if used in time will work wonders. Pulmonary Phthisis. Pathologists recognize a form of chronic de- struction of lung tissue, not characterized by the presence in the diseased tissue of the tubercle bacilli. It is in this variety of pulmonary disease that the Oxygen compound has won its greatest laurels. It aids in delaying and often stops the necrotic process going on. It supplies oxygen to the blood, which, owing to the diseased condition of many air vesicles, is receiving a supply of that substance far less than necessary for the healthful state of the system. By its inhalation under press- ure it aids in expanding and opening up air vesi- cles which are not yet diseased, but which have collapsed and whose walls are adherent, thus ren- dering them fit localities for the starting of fresh points of lung necrosis. With the above facts well known and proved, what conscientious physician will fail to try, in cases calling for its administration, this agent so potent for good ? The time is past for deriding it, and placing it in the same category with much- advertised nostrums. It is not a “ cure all,” but it has certain well-defined and well-understood fields of action and in these conditions it is supreme. In justice to patients, every physician should in- vestigate and make a trial of this powerful agency. Having once seen its effects, it is easy to prophecy that its administration will constantly become more and more frequent, with consequent increas- ing benefit to patients suffering from disease which come within its legitimate sphere of action.

OXYGEN COMPOUND G0.,«€ 498 THIRD AVENUE, NEAR 34th STREET. A. CARD. New York, October 15, 1891. We would call your attention to the fact that we are now enabled to furnish Oxygen Compound Gas of superior quality for the nominal price of $10 for one hundred and fifty gallons. This gas is manufactured with great care under the most experienced supervision and is exactly what we represent it to be, viz. two parts oxygen and one part nitrogen mon-oxide, there being absolutely no dilution by atmospheric air. This fact is of the utmost importance to physicians, as they are certain of the agent pre- scribed and can then note the effect in different cases. We would direct your attention to the following conditions in which this gas is highly recommended and where its efficiency is well known : Asphixiation by coal gas, sewer gas, illuminating gas and by drowning. In these cases the oxygen acts as nothing else can, its effect is immediate and the patient is instantly revived. In Phthisis Dvspnoea from all causes. Pneumonia, Heart Failure, CEdema of the lungs, and Anaemia the gas will furnish all the life giving properties of pure air without any exertion in breathing on the part of the patient. The treatment allows the patient to recuperate by the additional strength acquired in easy respirations. Our gas is put up in a convenient shape for handling, in cylinders containing one hundred and fifty gallons, and is ready for immediate use, being supplied with tubing, inhaler bottle, and mouth- piece. This apparatus we loan fora period of two mouths without charge, but as an especial favor, we ask that cylinders be returned as soon as empty. We can furnish this gas in all emergency cases at the shortest possible notice, being connected by telephone, No. 243 38th. All orders in the city we will fill immediately, and those out of town will be shipped by express the same day as when received. For detailed particulars with cases cited and treatment discussed by the physicians in charge, send for pamphlet. Soliciting your patronage, we remain, yours truly, MEDICAL OXYGEN COMPOUND CO. N.
