Diaphragmatic breathing

“ I should be sorry if what I have said regarding the diaphragm were to be construed as belittling its [Pg 45] importance as an aid to artistic breathing. My comments are directed against the exaggerated importance attached to it by advocates of wholly diaphragmatic or abdominal breathing, when it is capable of physiological demonstration that violent effort will accomplish no more with the diaphragm than that accommodating muscle accomplishes of its own accord when the singer, in taking in breath, correctly applies the principles of mixed costal and diaphragmatic respiration. ”

“ It is a curious fact that until recent years the world generally, the medical profession included, held the opinion that there is a fundamental difference between men and women in breathing. Observation of the natural breathing of boys and girls would soon prove the absurdity of this opinion. Owing to the universal use of the corset, thoracic breathing, or chest breathing, the result of the artificial constriction of the body at and below the waist line, appeared to be the natural method of breathing for women, whereas diaphragmatic breathing was recognized as proper and natural for men. ”

“ Abdominal or diaphragmatic breathing is a downward perpendicular force just as ugly and as ineffective, besides being positively harmful, the pressure of the diaphragm, if violently exerted, often being injurious to the organs of the body contained in the abdominal cavity and especially to the female organs of sex. ”

“ Return to original position, repeat the exercise, flinging the body to the right side. Inhale while swinging backward, exhale while returning to position.
Diaphragmatic Breathing
The diaphragm is a large, flat muscle, resembling a saucer, which forms the division between the chest cavity and the abdominal cavity. By downward expansion it causes the lungs to expand likewise and to suck in the air. The pressure of air being greater on the outside of the body than within, it rushes in and fills the vacuum created by the descending diaphragm. ”

“ To say that no other style of breathing excepting that which has been described as correct, the mixed costal and diaphragmatic, ever should be employed, would be a mistake, but any other should be employed, when at all, only for rare and specific effects. ”

“ Vocal resonance corresponds with the respiratory murmur according to accepted laws. When there is pressure on the principal bronchus on one or both sides, one can detect either a snoring, increased bronchial respiration, or else, if the pressure decidedly narrows the calibre of the bronchus, the breathing becomes feeble or wheezing. Expiration may be prolonged and sonorous in character, with or without râles. The pressure is rarely equal on the two sides. ”

“ Another mode in which violent effort injures the lungs is by the rapid and continued inhalation of great quantities of air during rapid breathing, so as to dilate the lungs suddenly to their fullest extent. Sometimes from irregular distribution of the ærial current or from the want of tone in a particular part of the lung that gives way under the pressure and the air cells become overdistended or ruptured. ”

“ Here there must be no exertion whatever in the chest muscles. The lungs must seem to expand from the pressure of the air alone, as independently as a rubber ball will expand when external pressure is removed, and they must be allowed to expel the air with the same independence. In this way the growth of breathing power will be slow, but it will be sure and delightfully restful. Frequent, full, quiet breaths might be the means of relief to many sufferers, if only they would take the trouble to practise them faithfully,—a very slight effort compared with the result which will surely ensue. ”

“ Simple diffusion through the narrow bronchial tubes could not possibly bring oxygen into the lung sacs fast enough to supply the requirements of the blood flowing through their walls. The situation is met by active lung ventilation; that is, by forcibly changing the air in the lungs at frequent intervals. The way in which this is done is, as we all know, by breathing. Breathing is nothing but a bellows movement of the chest by which air is alternately expelled and allowed to enter. ”

“ Ordinarily, we hear no breath sounds. The absence, however, of breath sounds as a sign of pleuritic effusion is by no means a constant one. When the fluid contains many fibrinous bands, binding the lung down to the costal pleura, or when the effusion is very large and forces the air nearly out of the pulmonary tissue, pressing it into a firm mass against the vertebral column (at a point corresponding to the spine of the scapula) , or when the lung is solid simply from the residual air being pressed out of it, diffused bronchial tubular breathing is heard. ”

“ The phenomena attending asphyxia are as follows. As soon as the oxygen in the arterial blood, through exclusion of air, sinks below the normal, the respiratory movements grow deeper and at the same time more frequent; both the inspiratory and expiratory phases are exaggerated, the supplementary respiratory muscles are brought into play, and the breathing becomes hurried. As the blood becomes more and more venous, the respiratory movements continue to increase both in force and frequency. ”

“ Thus the greater muscular effort in ordinary breathing is used to enlarge the cavity of the thorax or chest, producing inspiration—not, as in birds, to diminish the cavity, producing expiration. In other words, the air is forced into mammalian lungs by atmospheric pressure when, through muscular effort, the chest enlarges; and the air is expelled simply by the elastic reaction of the lungs and chest. ”

“ Nature had rather need of annular tubes, such as those of the bronchia, in order that they might always remain open, not have been liable to collapse; and that they might continue entirely free from blood, lest the liquid should interfere with the passage of the air, as it so obviously does when the lungs labour from being either greatly oppressed or loaded in a less degree with phlegm, as they are when the breathing is performed with a sibilous or rattling noise. ”

“ When all the ingoing impulses from the lungs, etc., are cut off, if respiration does not actually cease, it is carried out in a way so ineffective that life cannot be long sustained. It follows that as the muscular contractions necessary for the chest and other respiratory movements are dependent on the impulses passing in from the lungs, etc., breathing belongs to the class of movements known as reflex—chiefly so, at all events. ”

“ When the respiration is difficult, additional forces are brought into play. Thus when the windpipe and bronchial tubes are obstructed, as in croup, asthma, or consumption, many additional muscles are made use of to help the lungs to expand. The position which asthmatics often assume, with arms raised to grasp something for support, is from the need of the sufferer to get a fixed point from which the muscles of the arm and chest may act forcibly in raising the ribs, and thus securing more comfortable breathing. ”

“ The lungs in their natural state are charged with a large quantity of impure air; this being a portion of the carbonic acid gas which is formed during respiration, but which, after each expiration, remains lodged in the involved passages of the pulmonary tubes. By breathing hard for a short time, as a person does after violent exercise, this impure air is expelled, and its place is supplied by pure atmospheric air, by which a person will be enabled to hold his breath much longer than without such precaution. ”

“ Every time the chest cavity is emptied by the expiration of the breath a partial vacuum is created which exerts a tremendous suction power. It is one of the principal forces concerned in the return of the venous blood to the heart, but it also exerts a like effect upon the lymphatic current, hence deep breathing is a valuable exercise for those unable to take any other.
In commencing the development of the body by any system of physical culture, the first and most important thing to do is to develop the lungs. Good lungs and good digestion go together. ”

“ That nervousness keeps all the muscles of the body in a state of unnatural strain, and this strain has even caused us to breathe differently from what nature planned. The very first step toward good voice method is to bring the breathing apparatus back to working order. As said above, the chief organ of respiration is the diaphragm, and that is a large muscle which cuts across the body at the edge of the ribs. Its centre, right in the middle of the body is constantly moving downward and upward. When it goes down the breath enters the body; when it comes up the breath comes out. ”

“ This, as a matter of fact, is the case; anyone can easily prove on himself, by breathing deeply and rapidly for a minute or two, that the automatic control of breathing is temporarily suspended immediately after. It follows naturally that one can hold the breath a good deal longer if the lungs are overventilated for a short time just before the attempt is made. This also can be easily proved. Prolonged overventilation of the lungs has, likewise, a number of other effects, all of which are due to cutting down the total amount of carbon dioxide in the body. ”

“ It is, however, known by experiments on animals that if the inhalation be prolonged beyond the period necessary to produce these effects, the respiratory functions are interfered with by the insensibility extending to the nerves on which they depend. The breathing of an animal thus treated becomes irregular, feeble, or laborious, and death ensues. However nearly dead from inhalation of ether vapour the animal may be, provided respiration has not actually ceased, it always recovers when allowed to breathe fresh air. ”

“ After reaction is established the patient is in great danger of congestion of the lungs, and unless perfect rest is maintained for at least forty-eight hours he may be seized with difficulty of breathing, and death ensue if immediate relief is not afforded. In such cases a large mustard plaster is placed upon his chest, and, if he gasps for breath before the mustard takes effect, his breathing is assisted by the careful repetition of the artificial respiration. ”

“ Let us see what will happen if while we are sitting quietly we begin to breathe deeply and rapidly, overventilating the lungs. So far as oxygen is concerned, this will make no difference at all, since, as we have already seen, the ordinary automatic breathing keeps the blood charged with all the oxygen it can hold. What overventilation does is to sweep out the carbon dioxide from the lung sacs more rapidly than usual and this permits of a correspondingly more rapid outward diffusion of carbon dioxide from the blood. ”

“ I have in mind numerous instances where the singer, under the impression that he was practicing deep breathing tried to control the breath with the lower abdominal muscles, but no matter how great the effort made there was little tonal response, for the reason that the pressure exerted was not against the lungs but against the contents of the abdomen. The diaphragm is the point of control. The lungs lie above it, not below it. To concentrate the thought on the lower abdominal muscles means to lose control of the diaphragm, the most important thing involved in breath management. ”

“ Writers and professors advocating exclusively so-called diaphragmatic, or costal, or abdominal respiration, are incorrect and perfectly deceived. The diaphragm, the ribs, and the muscles of the abdomen must all do more or less their special work, in order to carry on a normal and healthy respiratory act. An eminent physician, Dr. Ed. Fournié of Paris, says: “He who respires exclusively by one or the other of these alone (diaphragm, ribs or abdomen) must be indeed a sick man.” ”

“ Frequency of Respiration.—It is usually estimated that we breathe once during every four beats of the heart, or about eighteen times in a minute. There is, of course, a close relation between the heart and lungs, and whatever modifies the pulse, in like manner affects the breathing. When the action of the heart is hurried, a larger amount of blood is sent to the lungs, and, as the consequence, they must act more rapidly. Occasionally, the heart beats so very forcibly that the lungs cannot keep pace with it, and then we experience a peculiar sense of {130}distress from the want of air. ”

“ Many of the air cells of the lungs become inactive by reason of incomplete breathing, and often become almost atrophied. One who has practised imperfect breathing for years will find it not so easy to stimulate all these ill-used air cells into activity all at once by the Complete Breath, but this exercise will do much toward bringing about the desired result, and is worth study and practice. ”

“ The one important thing in breath management is the diaphragm. If the student has the right action of the diaphragm he will have no further trouble with breath control. In my Systematic Voice Training will be found a list of exercises which thoroughly cover the subject of breath control and if properly used will correct all errors. Let this be understood, that there is nothing in correct breathing that should make one tired. On the contrary the practice of breathing should leave one refreshed. Above all, the student should never make himself rigid when trying to control the flow of breath. ”
