Aspiration pneumonia is a type of lung infection that is due to a relatively large amount of material from the stomach or mouth entering the lungs. [1] Signs and symptoms often include fever and cough of relatively rapid onset. [ 1 ]
Aspiration pneumonia is when bacteria is carried into the respiratory tract via aspiration and subsequently causes an infection of the lung. Any substance or object that is aspirated into the airway has the potential of carrying infectious agents with it into the respiratory tract.
Aspiration Pneumonia: If particles enter the lungs, it can cause lung infections. This can happen from aspirating a foreign body. [8] Structural Changes: Repeating obstruction or trauma may scar or narrow the upper airway. This is called subglottic or tracheal stenosis. [9]
In adults the most common source of aspiration pneumonia is aspiration of oropharyngeal secretions or gastric contents. In children the most common cause is aspiration of infected amniotic fluid, or vaginal secretions. Severe periodontal or gingival diseases are important risk factors for establishment of an anaerobic pleuropulmonary infection.
Pneumonia fills the lung's alveoli with fluid, hindering oxygenation. The alveolus on the left is normal, whereas the one on the right is full of fluid from pneumonia. Pneumonia frequently starts as an upper respiratory tract infection that moves into the lower respiratory tract. [55] It is a type of pneumonitis (lung inflammation). [56]
White lung pneumonia is not a specific type of pneumonia, Dr. Ganjian says. “It is simply a term that has been used to describe pneumonia that appears white on chest X-rays,” he explains.
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. If unresolved, continued inflammation can ...
Likely behind the trending but misleading “white lung” phrase: a fear that cases of pneumonia of an “unknown origin” in China have spread to European countries, and to the U.S.
