Hemoptysis is defined as the spitting of blood derived from the lungs or bronchial tubes as a result of pulmonary or ' bronchial hemorrhage1. Hemoptysis is classified as non-massive or massive based on the volume of blood loss; however, there are no uniform definitions for these categories. In this article, hemoptysis is considered non-massive if blood loss is less than 200 ml per day. The lungs receive blood from the pulmonary and bronchial arterial systems. The low-pressure pulmonary system tends to produce small-volume hemoptysis, whereas bleeding from the bronchial system, which is at systemic pressure, tends to be pro fuse.
