EIPH results from strenuous sprint exercise and/or pathologic changes in the equine athlete. It is defined as the presence of blood in the tracheobronchial tree (system of tubes in the lungs) following strenuous exercise. EIPH generally occurs soon after training begins, and tends to increase in incidence with age.
What causes horses to bleed?
