What is the most common pathophysiology of pneumonia?
thousands of microorganisms enter the nose daily, including bacteria, viruses and mushrooms. Infections from these organisms can cause pathophysiology of pneumonia. The most common causes of pathophysiology of pneumonia are such bacteria and viruses. After infection, lung inflammation usually occurs and pneumonia usually develops. In the nose there are hairs that filter inhalation air. Sneezing and cough occurs as reflective mechanisms for the exclusion of harmful products that enter the nose. The presence of friendly bacteria inside the nose also usually prevents harmful organisms from invasion and propagation. However, when the health of the person is disrupted, these normal defense of the body usually weaken and allow the rooting of infection and pneumonia. Examples include malnutrition, the presence of chronic diseases, Immune deficiencies and the use of some strong drugs. Smoking, corrosive gases inhalation, alcohol intake and genetic disorders could also lead to infection. In the lungs, many cells are able to absorb invasive organisms and kill them. When orgaNisms exceed these cells, other cells of the immune system usually collected in the lungs to help stop the infection. During this process, inflammation and secretion increase, which usually leads to fever and cough with sputum production.
symptoms of pneumonia differ. Some patients show mild symptoms, while others will have serious manifestations that may be life -threatening. The first symptoms may include fever and cough and could be misinterpreted as a simple case of flu. Continued fever, sweating, cough, breathing problems, chills, headache, fatigue, muscle pain and chest pain are common symptoms that are usually perceived as pneumonia.
Pathophysiologyusually depends on the infection. Bacterial pneumonia may be caused by Streptococcus pneumoniae, Haemophilus influenzae, mycoplasma pneumoniae, staphylococcus aureus, pseudomonas aeruginosa, Klebsiella pneumoniae, Moraxella Catarralis and Legionalla. Viral pneumonia can be caused by adenoviruses, respiratory syncytial viruses, influenza A and B and parainfluenza viruses.
mold pnemonia could occur from the histoplasma capsulatum infection, coccidioids of immmitis, pneumocystis Jiroveci or cryptococcus neoformans. Infections with mushrooms are rare. It usually occurs in patients whose immune systems have been endangered, such as patients with syndrome of the acquired immune deficiency (AIDS).
Some parasites can also attack the lungs and cause parasitic pneumonia. These parasites could include Ascaris Lumbricoides, Toxoplasma Gondii and Strongyloides Stercoralis. Aspiration of pneumonia can occur when the stomach content gets into the lungs. This usually occurs in patients with strokes who have abnormal swallowing reflexes.
