Occult pneumonia is a pneumonia that is not observable directly by the eye, but can only be shown indirectly, especially by radiography. Occult pneumonia can be made visible by chest X-rays . The general symptoms cough for more than 10 days and fever for more than 3 days can indicate the presence of occult pneumonia, just as a temperature of 39 ...
A chest x-ray is typically performed in cases where any pneumonia is suspected, including aspiration pneumonia. [18] Findings on chest x-ray supportive of aspiration pneumonia include localized consolidation depending on the patient's position when the aspiration occurred. [18]
Pneumonitis describes general inflammation of lung tissue. [1] [2] Possible causative agents include radiation therapy of the chest, [3] exposure to medications used during chemo-therapy, the inhalation of debris (e.g., animal dander), aspiration, herbicides or fluorocarbons and some systemic diseases.
Chest X-rays and X-ray computed tomography (CT) can reveal areas of opacity (seen as white), indicating consolidation. [13] CAP does not always appear on x-rays, sometimes because the disease is in its initial stages or involves a part of the lung not clearly visible on x-ray. In some cases, chest CT can reveal pneumonia not seen on x-rays.
Airway inflammation is increased during the exacerbation resulting in increased hyperinflation, reduced expiratory air flow and decreased gas exchange. [1] [2] Exacerbations can be classified as mild, moderate, and severe. [3] As COPD progresses, exacerbations tend to become more frequent, the average being about three episodes per year. [4]
A routine chest X-ray is not always necessary for people who have symptoms of a lower respiratory tract infection. [4] Influenza affects both the upper and lower respiratory tracts. [citation needed] Antibiotics are the first line treatment for pneumonia; however, they are neither effective nor indicated for parasitic or viral infections. Acute ...
It is the most common bacterial pneumonia found in adults, the most common type of community-acquired pneumonia, and one of the common types of pneumococcal infection. The estimated number of Americans with pneumococcal pneumonia is 900,000 annually, with almost 400,000 cases hospitalized and fatalities accounting for 5-7% of these cases. [2]
Difficulties breathing can quickly progress to an inability to breathe without support (respiratory failure). [ citation needed ] Acute interstitial pneumonitis typically progresses rapidly, with hospitalization and mechanical ventilation often required only days to weeks after initial symptoms of cough , fever, and difficulties breathing develop.
