Recurrent airway obstruction, also known as broken wind, heaves, wind-broke horse, or sometimes by the term usually reserved for humans, chronic obstructive pulmonary disease or disorder (COPD) – it is a respiratory disease or chronic condition of horses involving an allergic bronchitis characterised by wheezing, coughing and laboured breathing.
Peribronchial cuffing, also referred to as peribronchial thickening or bronchial wall thickening, is a radiologic sign which occurs when excess fluid or mucus buildup in the small airway passages of the lung causes localized patches of atelectasis (lung collapse). [1] This causes the area around the bronchus to appear more prominent on an X-ray ...
Also, this disease is predominantly found in the upper lobe with centrilobar ground glass nodules. Importantly, no fibrosis is involved, just bronchial wall thickening. Treatment is to stop smoking. The appearance is similar to desquamative interstitial pneumonia, and some have suggested that the two conditions are caused by the same processes. [5]
Approximately 43 to 75% of horses have blood in the trachea and bronchi following a single post-race endoscopic examination. [7] In one study, all horses endoscoped on at least three separate occasions following racing had EIPH at least once. [8] Epistaxis (blood coming from one or both nostrils) is much less common, occurring in 0.25–13% of ...
Treatments to slow down the progression of this chronic disease include keeping bronchial airways clear and secretions weakened through various forms of airway clearance. Aggressively treating bronchial infections with antibiotics to prevent the destructive cycle of infection, damage to bronchi and bronchioles, and more infection is also ...
An adult horse has an average rate of respiration at rest of 12 to 24 breaths per minute. [3] Young foals have higher resting respiratory rates than adult horses, usually 36 to 40 breaths per minute. [3] Heat and humidity can raise the respiration rate considerably, especially if the horse has a dark coat and is in the sun.
Dictyocaulus viviparus found in the bronchi of a calf during necropsy (arrow). Parasitic bronchitis, also known as hoose, husk, or verminous bronchitis, [1] is a disease of sheep, cattle, goats, [2] and swine caused by the presence of various species of parasite, commonly known as lungworms, [3] in the bronchial tubes or in the lungs.
Strangles (also called equine distemper) is a contagious upper respiratory tract infection of horses and other equines caused by a Gram-positive bacterium, Streptococcus equi. [1] As a result, the lymph nodes swell, compressing the pharynx , larynx , and trachea , and can cause airway obstruction leading to death, hence the name strangles. [ 2 ]
