Pathophysiology of Pneumonia - Free download as Word Doc (.doc), PDF File (.pdf) or read online for free. Pneumonia is a pulmonary infection that is characterized by the inflammation of the lung parenchyma. The pathophysiology of pneumonia is characterized by four stages.

i will help in anyway possible!

Important contributors to the growing incidence are increased life expectancy, multiple chronic diseases, and imm… Inhalation of infectious particles is probably the most important pathogenetic mechanism in the development of community-acquired pneumonia, with particular importance of pneumonia caused by Legionella species and M. tuberculosis. The first stage of the disease occurs within 24 hours of infection and it is distinguished by vascular congestion and alveolar edema. When an individual has pneumonia, the alveoli in the lungs are filled with pus and fluid, which makes breathing painful and limits oxygen intake. The inflammation could occur due to a bacterial, viral, or fungal infection. any question, additional or misinterpretation, pls kindly, message me or comment, thank you all. thanks to all those who view or download my files, dont forget to post comments, thanks! However, there is no clear explanation for this phenomenon (1-4). This HealthHearty write-up provides information on the pathophysiology of pneumonia. Pneumonia is a form of acute respiratory tract infection (ARTI) that affects the lungs. Hospital-acquired pneumonia (HAP) is pneumonia that occurs more than 48 hours after admission1and without any antecedent signs of infection at the timeofhospitaladmission.ThedistinctionofHAPfromcommunity-acquiredpneumo- nia is important, as patients with HAP are susceptible to pneumonia from a different and potentially more virulent … Pathophysiology Six mechanisms have been identified in the pathogenesis of pneumonia in immunocompetent adults. Community-acquired pneumonia (CAP) remains the main cause of death from infectious disease globally and is associated with considerable impact on morbidity and mortality especially in the elderly. The development of pneumonia requires that the pathogen reach the alveoli and that host defenses are overwhelmed by microorganism virulence or by the inoculum size. Several studies have also indicated that its incidence has risen over recent decades, and that more patients now require hospitalization. Pneumonia has many possible causes, but the most common are bacteria and viruses. It can be bacterial, viral or even fungal. The lungs are also invaded by bacteria and few neutrophils. Pathophysiology: Pneumonia is an infection that inflames the air sacs in one or both lungs. Pneumonia is a lung condition wherein the parenchyma of the lung becomes inflamed. comprehensive outline of the pathological process of pneumonia.
