What Is The Definition Of Pneumonia
See details: The most common definition is an infection involving the lung. Several noninfectious disorders can cause inflammation of the lung which is not due to infection.
Atypical organisms: Atypical pneumonia is so called because the causative organisms are not the usual ones associated with most cases of pneumonia. Besides mycoplasma, chlamydia & legionella, many viruses, fungi & protozoa can cause atypical pneumonia as well. Symptoms & signs can be atypical - dry cough, minimal or no fever, absence of lobar consolidation or leucocytosis etc. Also called walking pneumonia.
Inhaling liquid: Our breathing and digestive systems both start from the throat. When we eat or drink something, our body stops our breathing for a moment until we finish swallowing. Then we breathe again. When we breathe with liquid in our throat, we are likely to suck the liquid into the lungs with the air. This is called aspiration. If it is irritating or infected, the problem is called aspiration pneumonia.See 1 more doctor answer
Inflammation: Interstitial pneumonia is an inflammatory process that affects the walls of the small air sacs in the lungs causing them to thicken & cause difficulties with oxygentation. Several infectious & non-infectious processes can cause accumulation of inflammatory cells & fibrous deposits in the walls of the air sacs causing the lungs to become stiffer & unable to maintain adequate gas exchange.
Respiratory distress: A description of a newborn with pneumonia is a newborn born to a mother who may have signs or symptoms of an infection. Thus, a newborn may be born with respiratory difficulty (ie. rapid of difficult breathing) and require respiratory support (Oxygen and/or Ventilation Support). They may or not have an elevated temperature. A Chest X-ray will document chest infiltrates.
Extrinsic alveolitis: A non-ige mediated, immunologically mediated lung disease with generalized symptoms due to sensitization of a wide variety of inhaled organic dusts. These include molds, birds and other antigens found especially in workplaces and hobbies. It affects lung alveoli and can have acute (appears like viral pneumonia), subacute and chronic forms. No one test confirms the disease.See 1 more doctor answer
Pneumonia: Pneumonia is an infection of the lungs caused by bacteria, viruses, or fungus. It can be diagnosed by a physician by chest x-ray in most cases. Most cases (if caught early enough) can be easily treated as an outpatient. It becomes more problematic in the elderly, and more medically frail patients so get evaluated by your doctor if you believe you have it!See 2 more doctor answers
Lung infection / rxn: Any reaction in the lung that causes typical symptoms (fever, cough with phlegm, etc.) along with a visible abnormality on X-ray is considered pneumonia. Most often, it is a (bacterial) infection; however, pneumonia can be caused by a hypersensitivity (immune) reaction, viruses, exposure to harmful chemicals or inorganic material like coal dust, asbestos, & the like, radiation, & multiple others.See 1 more doctor answer
Pneumonia: Pneumonia is an infection of the lungs causes by bacteria or virus. Bacterial pneumonia is more common in community and needs antibiotics . The prognosis depends on various factors like, immunity, age, severity of pneumonia, associated medical conditions like other lung disease, smoking, diabetes etc. the patient will need to see a doctor for exam , investigation and treatment.See 2 more doctor answers
Lots of things: Lots of things can cause pneumonia, which is an infection of the lung. Bacteria, viruses & fungi can all cause pneumonia. However, so can aspiration which occurs when choking on something, typically stomach contents. Appropriate vaccines are very useful in decreasing certain, but not all, pneumonias.
