Inflammation of the lung parenchyma characterized by consolidation of the affected part, the alveolar air spaces being filled with exudate, inflammatory cells, and fibrin. Most cases are due to infection by bacteria or viruses, a few to inhalation of chemicals or trauma to the chest wall, and a few to rickettsiae, fungi, and yeasts. Distribution may be lobar, segmental, or lobular; when lobular and associated with bronchitis, it is termed bronchopneumonia |

| Any condition in which the number of red blood cells/mm3, the amount of hemoglobin in 100 mL of blood, and/or the volume of packed red blood cells/100 mL of blood are less than normal; clinically, generally pertaining to the concentration of oxygen-transporting material in a designated volume of blood, in contrast to total quantities as in oligocythemia, oligochromemia, and oligemia. Anemia is frequently manifested by pallor of the skin and mucous membranes, shortness of breath, palpitations of the heart, soft systolic murmurs, lethargy, and tendency to fatigue. |

| increased fluid in the pleural space; can cause shortness of breath by compression of the lung and/or increased intrathoracic pressure resulting in mediastinal shift and increased work of breathing; a transudative effusion has low protein content and is usually due to heart failure, uremia, or hypoalbuminemia; an exudative effusion has high protein and cell count and is due most often to inflammation, malignancy, or infection; an infected pleural effusion is an empyema; a pleural effusion associated with pneumonia is a parapneumonic effusion; a pleural effusion without actual infection but with signs of a high degree of inflammation (low pH, low glucose, high lactate dehydrogenase, many white blood cells) is a complex pleural effusion and is frequently associated with pneumonia; a loculated pleural effusion is not free flowing in the pleural space but rather confined to one or more fixed pockets. |
