Often so slight as to be evidently due to an effort made by the patient to free hisĬhest from the difficulty of respiration. Very much in different attacks of the disease, and in different individuals, and is Sometimes violent, and may generally be known by its peculiar intonation. The cough in cases of asthma is also to a certain extent peculiar. Rise to a dry sound, the moist rhonchi occurring only when there is some liquid secreted. Some of these rhonchi are always produced in every paroxysm ofĪsthma, being caused by the swelling of the mucous membrane, which of course gives With the mucous - that is, the liquid is secreted in the smaller tubes, which of course Is much liquid secretion there is a sub-crepitant rhonchus heard at the same time Rhonchus, both in inspiration and expiration not fixed in any portion of the chest,Īlmost as soon as they appear, some trace of mucous rhonchus may also be heard, generallyĪt the base of the lungs sometimes, however, there is little or no liquid in theĬhest, and the sounds are limited to the sonorous and sibilant rhonchi. This is at first the sonorous or sibilant More or less rhonchus to be heard in the chest. Of breathing continues for a certain time, a few hours, for example, there is always The rhonchi and other signs of bronchial irritation are heard if theĪttack is accidentally complicated with acute bronchitis. Is occasionally heard at a distance from the patient, is produced almost exclusively
Sound is feeble, but at first there is generally no rhonchus the wheezing, which If the respiration be examined, the inspiratory No decided signs of bronchial inflammation. 490.Īll who are affected with the disease are liable to sudden and violent paroxysms ofĭyspnea, or to slighter derangement of the respiration at the same time there are The inflammation to the contiguous air-cells. To sag to the dependent parts and induce dilatation of the tubes with extension of In oldĪge the bronchial mucosa is less capable of expelling the mucus, which is more apt Similar dangers if the process extends from the larger to the smaller tubes. Rales are subcrepitant and numerous and there may be areas of defective resonanceĪnd of feeble or distant tubular breathing. This extension is indicated by changes in physical signs. In measles and whooping-cough, the ordinaryīronchial catarrh is very apt to descend to the finer tubes, which become dilatedĪnd plugged with muco-pus, inducing areas of collapse, and finally broncho-pneumonia.

In the early stage, piping sibilant rales are everywhere to be heard. On palpation the bronchial fremitus may often be felt. However, in which the breathing is rapid and when the smaller tubes are involved there The respiratory movementsĪre not greatly increased in frequency unless the fever is high. Grains, while others have undergone the myelin degeneration. The sputum is made up largely of pus-cells, withĪ variable number of the large round alveolar cells, many of which contain carbon With the loosening of theĬough great relief is a experienced. At first the cough is dry, but in a few days the secretionīecomes muco-purulent and abundant, and finally purulent. It comes on in paroxysms which rack andĭuring severe spells the pain may be very intense beneath the sternum and along theĪttachments of the diaphragm. The cough is rough at first, cuttingĪnd sore, and often of a ringing character. Sternum and a sensation of oppression in the chest.
