32 THE EQUINE HOSPITAL FORMULARY. 



Asthma. 



An animal suffering from this disease is afflicted with 

 paroxysms of dyspnoea, probably produced by spasm of the 

 circular muscles of the smaller bronchial tubes. Hereby a 

 certain degree of obstruction is caused, and hence respira- 

 tion is often accompanied by a marked wheezing noise. 

 The paroxysmal dyspnoea, being expiratory in nature, is 

 accompanied by a depression of the diaphragm and 

 weakened breathing. There are also sonorous and sibilant 

 rales. It is important to improve the general condition.
