Jason Y1 - 2021 N1 - T2 - The Atlas of Emergency Medicine, 5e AB - Sputum is expectorant from the lungs and respiratory passages that contains mucus and pus and is a clue to the severity of respiratory illness. While microscopic examination provides the most accurate clues to illness, gross examination provides valuable information. Color, consistency, and volume are features that provide insight to the cause and severity of illness. Bloody sputum or hemoptysis (see Fig. 25.47) may occur in streaks or in life-threatening amounts. Acute bronchitis, pneumonia, lung cancer, tuberculosis, bronchiectasis, lung abscess, pulmonary embolism, and pulmonary infarction are causes of hemoptysis. Pink or white frothy sputum suggests pulmonary edema. SN - PB - McGraw-Hill CY - New York, NY Y2 - 2024/03/28 UR - accessemergencymedicine.mhmedical.com/content.aspx?aid=1181053048 ER -
