Hemoptysis refers to the bleeding of trachea, bronchus or lung tissue, the expectoration of blood from the mouth through coughing. The quantity of blood is not completely consistent with severity of disease. Small amount of bleeding sometimes only shows blood-tinged sputum, but blood effused from nose and mouth could block respiratory tract, and even cause suffocation in massive hemoptysis.
