Respiratory System Examination

The lungs of the horses are considerably bigger and they breathe less frequently when compared to the humans. When the horse is resting, the respiratory rate is between 6-16 times per minute. This rate increases during exercise. When the horse gallops, it is possible to hear the horse exhaling with each step. Respiration rate that increases during training could return to normal in a little while when resting. If the rate of respiration does not return to normal during rest, the first thing that will come to mind is that the horse's condition is weak.

Nasal discharge that may be observed in respiratory system diseases

It is known that there are more than 100 diseases affecting the respiratory system from the nasal cavity to the lungs. Sometimes infections arising from microorganisms could be detected (i.e. flu, strangles) whereas sometimes problems not related to infections could be spotted (i.e. roaring, soft palate problems). Care and environmental conditions, measures to be taken upon the arrival of a new horse to the facility and vaccinations etc should be taken into consideration in preventing infectious respiratory system diseases. Symptoms observed in respiratory system problems can range from mild nasal discharge to severe coughing and respiratory distress.

Respiratory system examinations could be pathognomonic and constitute an essential part of the pre-purchase examination. Some conditions that do not cause any symptoms while the horse is resting and under normal conditions can be diagnosed by applications such as cough reflex test and condition test.
