EIPH or Exercise Induced Pulmonary Haemorrhage is the condition of bleeding (haemorrhage) from blood vessels within the lung (pulmonary) which occurs during strenuous exercise. The condition is felt to be controlled through the medical application of furosemide, which has the effect of lowering the blood pressure and controlling the condition. A managed and controlled EIPH Program has been in place in Ontario since 1991 for both Thoroughbred and Standardbred racing at participating racetracks. Under strict guidelines, horses are allowed to enter the program and publication of their inclusion in the program is included in the race program for the information of the general public.
