You will please bear with me for a few minutes in my attempt at theory.
The annulling of pain, and, in some cases, its complete annihilation, can be accomplished in many ways. Narcotics, anaesthetics–local and internal–direct action of cold, and mesmeric or physiological influence, have all their advocates, and each will surely do its work. There is one thing about which, I think, we can all agree, as to these agencies; unless the will is partially and in some cases completely subjugated there can be no primary or secondary effect. The voluntary muscles must become wholly or partially paralyzed for the time. Telegraphic communication must be cut off from the brain, that there be no reflex action. It is not necessary there should be separate nerves to convey pleasure and pain any more than there should be two telegraphic wires to convey two messages.
If, then, we are certain of this, it matters little as to whether it was done by corpuscular poisoning and anaemia as from chloroform or hyperaemia from ether.
I think we are now prepared to show clearly the causes which effect the phenomena in "rapid breathing."
The first thing enlisted is the diversion of the will force in the act of forced respiration at a moment when the heart and lungs have been in normal reciprocal action (20 respirations to 80 pulsations), which act could not be made and carried up to 100 respirations per minute without such concentrated effort that ordinary pain could make no impression upon the brain while this abstraction is kept up.
Second. There is a specific effect resulting from enforced respiration of 100 to the minute, due to the excess of carbonic acid gas set free from the tissues, generated by this enforced normal act of throwing into the lungs five times the normal amount of oxygen in one minute demanded, when the heart has not been aroused to exalted action, which comes from violent exercise in running or where one is suddenly startled, which excess of carbonic acid cannot escape in the same ratio from the lungs, since the heart does not respond to the proportionate overaction of the lungs.
Third.–Hyperaemia is the last in this chain of effects, which is due to the excessive amount of air passing into the lungs preventing but little more than the normal quantity of blood from passing from the heart into the arterial circulation, but draws it up in the brain with its excess of carbonic acid gas to act also directly upon the brain as well as throughout the capillary and venous system, and as well upon the heart, the same as if it were suspended in that gas outside the body.
These are evident to the senses of any liberal observer who can witness a subject rapidly breathing.
Some ask why is not this same thing produced when one has been running rapidly for a few minutes? For a very good reason: in this case the rapid inhalations are preceded by the violent throes of the heart to propel the carbonized blood from the overworked tissues and have them set free at the lungs where the air is rushing in at the normal ratio of four to one. This is not an abnormal action, but is of necessity, or asphyxia would instantly result and the runner would drop. Such sometimes occurs where the runner exerts himself too violently at the very outset; and to do so he is compelled to hold his breath for this undue effort, and the heart cannot carry the blood fast enough. In this instance there is an approach to analgesia as from rapid breathing.
Let me take up the first factor–diversion of will--and show that nature invariably resorts to a sudden inhalation to prevent severe infliction of pain being felt. It is the panacea to childhood's frequent bruises and cuts, and every one will remember how when a finger has been hurt it is thrust into the mouth and a violent number of efforts at rapid inhalation is effected until ease comes. By others it is subdued by a fit of crying, which if you will but imitate the sobs, will find how frequently the respirations are made.
One is startled, and the heart would seem to jump out of the chest; in quick obedience to nature the person is found making a number of quick inhalations, which subdue the heart and pacify the will by diversion from the cause.
The same thing is observed in the lower animals. I will relate a case:
An elephant had been operated upon for a diseased eye which gave him great pain, for which he was unprepared, and he was wrathy at the keeper and surgeon. It soon passed off, and the result of the application was so beneficial to the animal that when brought out in a few days after, to have another touch of caustic to the part, he was prepared for them; and, just before the touch, he inflated the lungs to their fullest extent, which occupied more time than the effect of the caustic, when he made no effort at resistance and showed no manifestation of having been pained.
In many cases of extraction of the temporary teeth of children, I make them at the instant I grasp the tooth take one very violent inhalation, which is sufficient. Mesmeric anaesthesia can well be classified under diversion or subjugation of the will, but can be effected in but a small percentage of the cases. To rely upon this first or primary effect, except in instantaneous cases, would be failure.
The second factor is the one upon which I can rely in such of the cases as come into my care, save when I cannot induce them to make such a number of respirations as is absolutely necessary. The whole secret of success lies in the greatest number of respirations that can be effected in from 60 to 90 seconds, and that without any intermission. If the heart, by the alow method of respiration, is pulsating in ratio of four to one respiration, no effect can be induced.
When the respirations are, say, 100 to the minute, and made with all the energy the patient can muster, and are kept up while the operation is going on, there can hardly be a failure in the minor operations.
It is upon this point many of you may question the facts. Before I tried it for the first time upon my own person, I arrived at the same conclusion from a course of argument, that rapid breathing would control the heart's action and pacify it, and even reduce it below the normal standard under my urgent respirations.
In view of the many applications made I feel quite sure in my belief that, inasmuch as the heart's action is but slightly accelerated, though with less force from rapid breathing at the rate of 100 to the minute, there is such an excess of carbonic acid gas set free and crowding upon the heart and capillaries of the brain, without a chance to escape by the lungs, that it is the same to all intents as were carbonic acid breathed through the lungs in common air. Look at the result after this has been kept up for a minute or more? During the next minute the respirations are not more than one or two, and the heart has fallen really below, in some cases, the standard beat, showing most conclusively that once oxygenation has taken place and that the free carbonic acid gas has been so completely consumed, that there is no involuntary call through the pneumogastric nerve for a supply of oxygen.
If any physiological facts can be proven at all, then I feel quite sure of your verdict upon my side.
There is no one thing that goes so far to prove the theory of Lavoisier regarding the action of oxygen in the tissues and capillaries for converting carbon into carbonic acid gas instead of the lungs, as held prior to that time, and still held by many who are not posted in late experiments. At the time I commenced this practice I must confess I knew nothing of it. The study of my cases soon led me to the same theory of Lavoisier, as I could not make the phenomena agree with the old theory of carbonic acid generated only in the lungs.
When Vierordt was performing his experiments upon himself in rapid breathing from six times per minute to ninety-six, I cannot understand why he failed to observe and record what did certainly result–an extreme giddiness with muscular prostration and numbness in the peripheries of the hands and feet, with suffusion of the face, and such a loss of locomotion as to prevent standing erect without desiring support. Besides, the very great difference he found in the amount of carbonic acid retained in the circulation, the very cause of the phenomena just spoken of.
One thing comes in just here to account for the lack of respiration the minute after the violent effort. The residual air, which in a normal state is largely charged with carbonic acid, has been so completely exhausted that some moments are consumed before there is sufficient again to call upon the will for its discharge.
As to hyperaemia you will also assent, now that my second factor is explained; but it is so nearly allied to the direct effect of excessive respiration that we can well permit it to pass without argument. If hyperaemia is present, we have a more certain and rather more lasting effect.
In conclusion, I will attempt to prognosticate the application of this principle to the cure of many diseases of chronic nature, and especially tuberculosis; where from a diminished amount of air going into the lungs for want of capacity, and particularly for want of energy and inclination to breathe in full or excess, the tissues cannot get clear of their excrementitious material, and particularly the carbon, which must go to the lungs, this voluntary effort can be made frequently during the day to free the tissues and enable them to take nutritious material for their restoration to their standard of health.
Air will be found of far more value than ever before as one of the greatest of factors in nutrition, and which is as necessary as proper food, and without which every organization must become diseased, and no true assimilation can take place without a due amount of oxygen is hourly and daily supplied by this extra aid of volition which has been so long overlooked.
The pure oxygen treatment has certainly performed many cures; yet, when compared to the mechanical mixture and under the direct control of the will, at all times and seasons, there is no danger from excessive oxygenation as while oxygen is given. When every patient can be taught to rely upon this great safety valve of nature, there will be less need for medication, and the longevity of our race be increased with but little dread by mankind for that terrible monster consumption, which seems to have now unbounded control.
When this theory I have here given you to-night is fully comprehended by the medical world and taught the public, together with the kind of foods necessary for every one in their respective occupation, location, and climate, we may expect a vast change in their physical condition and a hope for the future which will brighten as time advances.
I herewith attach the sphygmographic tracings made upon myself by another, showing the state of the pulse as compared with the progress of the respiration.
ADDENDA
Sphygmographic tracings of the pulse of the essayist. Normal pulse 60 to the minute. Ten seconds necessary for the slip to pass under the instrument.
A, A¹, normal pulse.
B, pulse taken after breathing rapidly for 15 seconds when
20 respirations had been taken.
C, rapid breathing for 30 seconds, 43 respirations.
D, " " 45 " 76 "
E, " " 60 " 96 "
F, pulse taken after rapid breathing for one minute, as in E, where no respiration had as yet been taken after the essayist had kept it up for that one minute. This was after 10 seconds had intervened.
G, the same taken 50 seconds after, and still no respiration had been taken, the subject having no disposition to inhale, the blood having been over oxygenated.
The pulse in E shows after 96 respirations but 14, or 84 per minute, and the force nearly as in the normal at A, A1.
The record in B shows the force more markedly, but still normal in number.
F and G show very marked diminution in the force, but the number of pulsations not over 72 per minute; G particularly so, the heart needing the stimulus of the oxygen for full power.
The following incident which has but very recently been made known, gives most conclusive evidence of the truth of the theory and practice of rapid breathing.
A Mexican went into the office of a dentist in one of the Mexican cities to have a tooth extracted by nitrous oxide gas.
The dentist was not in, and the assistant was about to permit the patient to leave without removing the tooth, when the wife of the proprietor exclaimed that she had often assisted her husband in giving the gas, and that she would do so in this instance if the assistant would agree to extract the tooth. It was agreed. All being in readiness, the lady turned on as she supposed the gas, and the Mexican patient was ordered to breathe as fast as possible to make sure of the full effect and no doubt of the final success. The assistant was about to extract, but the wife insisted on his breathing more rapidly, whereupon the patient was observed to become very dark or purple in the face, which satisfied the lady that the full effect was manifested, and the tooth was extracted, to the great satisfaction of all concerned. While the gas was being taken by the Mexican the gasometer was noticed to rise higher and higher as the patient breathed faster, and not to sink as was usual when the gas had been previously administered. This led to an investigation of the reason of such an anomalous result, when to their utter surprise they found the valve was so turned by the wife that the Mexican had been breathing nothing but common air, and instead of exhaling into the surrounding air he violently forced it into the gasometer with the nitrous oxide gas, causing it to rise and not sink, which it should have done had the valve been properly turned by the passage of gas into the lungs of the patient.
No more beautiful and positive trial could happen, and might not again by accident or inadvertence happen again in a lifetime.
TAP FOR EFFERVESCING LIQUIDS
When a bottle of any liquor charged with carbonic acid under strong pressure, such as champagne, sparkling cider, seltzer water, etc., is uncorked, the contents often escape with considerable force, flow out, and are nearly all lost. Besides this, the noise made by the popping of the cork is not agreeable to most persons. To remedy these inconveniences there has been devised the simple apparatus which we represent in the accompanying cut, taken from La Nature. The device consists of a hollow, sharp-pointed tube, having one or two apertures in its upper extremity which are kept closed by a hollow piston fitting in the interior of the tube. This tube, or "tap," as it may be called, is supported on a firm base to which is attached a draught tube, and a small lever for actuating the piston. After the tap has been thrust through the cork of the bottle of liquor the contents may be drawn in any quantity and as often as wanted by simply pressing down the lever with the finger; this operation raises the piston so that its apertures correspond with those in the sides of the top, and the liquid thus finds access to the draught tube through the interior of the piston. By removing the pressure the piston descends and thus closes the vents. By means of this apparatus, then, the contents of any bottle of effervescing liquids may be as easily drawn off as are those contained in the ordinary siphon bottles in use.
