AI Article Synopsis
- Pneumonia is an infection in the lower respiratory tract that occurs when pathogens invade, causing inflammation and fluid buildup in the lungs.
- The Infectious Diseases Society of America defines it as new lung infiltrate accompanied by signs of infection like fever, cough with mucus, and low oxygen levels.
- There are three types of pneumonia: community-acquired, hospital-acquired, and ventilator-associated, each requiring different treatments based on severity and specific risk factors.
Article Abstract
Pneumonia is a lower respiratory tract infection caused by the inability to clear pathogens from the lower airway and alveoli. Cytokines and local inflammatory markers are released, causing further damage to the lungs through the accumulation of white blood cells and fluid congestion, leading to pus in the parenchyma. The Infectious Diseases Society of America defines pneumonia as the presence of new lung infiltrate with other clinical evidence supporting infection, including new fever, purulent sputum, leukocytosis, and decline in oxygenation. Importantly, lower respiratory infections remain the most deadly communicable disease. Pneumonia is subdivided into three categories: (1) community acquired, (2) hospital acquired, and (3) ventilator associated. Therapy for each differs based on the severity of the disease and the presence of risk factors for methicillin-resistant Staphylococcus aureus or Pseudomonas aeruginosa.
