hematemesis

the vomiting of blood. The appearance of the vomitus depends on the amount and character of the gastric contents at the time blood is vomited and on the length of time the blood has been in the stomach. Gastric acids change bright red blood to a brownish color and the vomitus is often described as 'coffee-ground' in color. Bright red blood in the vomitus indicates a fresh hemorrhage and little contact of the blood with gastric juices.
