Symptoms typically include some combination of productive or dry cough, chest pain, fever and difficulty breathing. Pneumonia is the infection and inflammation of air sacs in your lungs. The development of pneumonia requires that a pathogen reach the alveoli and that the host defenses are overwhelmed by microorganism virulence or … Constant exposure to contaminated air and frequent aspiration of nasopharyngeal flora make lung parenchyma susceptible to virulent microorganisms, commonly reaching the lower respiratory tract as inhaled and contaminated microdroplets. In the United States, common causes of viral pneumonia are influenza, respiratory syncytial virus (RSV), and SARS-CoV-2 (the virus that causes COVID-19). Sign in via OpenAthens. Pneumonia : More than 3 million cases of pneumonia occur annually in the United States. When the alveoli are filled with fluid or pus then proper gas exchange does not occur as well. Pneumonia affects children and families everywhere, but is most prevalent in South Asia and sub-Saharan Africa. Diagnosis. Although thoughtful application of what is known about the pathophysiology of the lung in pneumococcal pneumonia can help the clinician deploy most effectively the available technologies of respiratory support in these patients, even the best intensive supportive measures are frequently inadequate, and mortality rates for patients requiring such support remain unacceptably high. The pathophysiology of CAP involves both host defense and microbial virulence factors. comprehensive outline of the pathological process of pneumonia. Pneumonia is acute inflammation of the lungs caused by infection. A pneumonia outbreak associated with a new coronavirus of probable bat origin. 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 … Introduction.

The development of pneumonia requires that a pathogen reach the alveoli and that the host defenses are overwhelmed by microorganism virulence or by the inoculum size. It’s important for you to understand the pathophysiology of pneumonia, it’s signs and symptoms, what you need to assess for, and what nursing interventions you’ll need to do for it.
