DISSASES OF THE RKSPIRATORY ORGANS. 8 1 



Kinds of Respiration. The following terms are used in explain- 

 ing the various characteristic breathings. 



QUICK BREATHING — refers to an increased number of respira- 

 tions per minute, which may be due to exercise or disease. 



DIFFICULT BREATHING— is always the result of something ab- 

 nornal, and it is often a perfect guide to the trouble. 



STERTORIOUS BREATHING— is not to be confounded with diffi- 

 cult breathing. It is more of a snore-like breathing, and is due to a re- 

 laxation of the palate, and not to disease of this part. It is generally 

 associated with brain disease, when the consequent derangement of the 

 nervous functions causes the relaxation of the soft palate. 



ABDOMINAE BREATHING— is when the ribs are kept nearly 

 stationary, and the abdominal muscles assist in breathing to a greater 

 extent than is natural. The "belly" is seen to work like a bellows. In 

 pleurisy, owing to the pain caused by moving the ribs, abdominal 

 breathing is always present. 



THORACIC BREATHING— is the opposite of abdominal breathing, 

 that is the ribs rise and fall more than usual, while the abdomen re- 

 mains fixed. This is due to abdominal pains, such as peritonitis, etc. 



IRREGUEAR BREATHING— is shown to good advantage in 

 heaves, and often in acute diseases during their critical stage. 



Secretions. During the first days of an inflammatory disease no- 

 tice carefully the secretions. In a common cold, there is first dryness, 

 then watery discharge, followed by thick mucus. In pleurisy the 

 membranes are at first drj', which can be easily determined by putting 

 the ear against the chest over the affected part and there will be heard 

 the dry rubbing sound, like two pieces of paper rubbing one against the 

 other. 



Cough, The surface being congested there is usually an effort as if 

 to remove some source of irritation in the respiratory track. 



The DRY COUGH is heard during the first stages of a disease of the 

 respiratory organs. In pleurisy the cough is a dry one, and the animal 

 tries to suppress it. 



The MOIST COUGH is heard when the secretions have been re-es- 

 tablished. Cough is but a symptom — the effect of a disease. Roaring, 

 heaves, pleurisy, and pneumonia have each a cough peculiar to the 

 affection. 



Detecting Disease by Sound. Auscultation is the term ap- 

 plied to the detecting, of diseases of the organs within the chest by
