bloody sputum

Etymology: AS, blod + L, sputum, spittle
blood-tinged material expelled from the respiratory passages. The amount and color of blood in sputum expelled by coughing or clearing the throat may indicate the cause and location of the bleeding. Swallowed blood regurgitated from the stomach most often loses its vital coloring, however, thus eliminating the opportunity to judge the origin.


(spu'tum) plural.sputa [L.]
Mucus expelled from the lung by coughing. It may contain a variety of materials from the respiratory tract, including in some instances cellular debris, mucus, blood, pus, caseous material, and/or microorganisms.


A wide variety of illnesses, including typical and atypical pneumonias, tuberculosis, cancers of the lungs or bronchi, reactive airway disease, and occupational diseases of the lungs can be diagnosed with gram staining or culturing of sputum, cytological examination of sputum, or the use of special stains and microscopic techniques.


Sputum color or thickness cannot be relied on to diagnose any particular illness.
