Aspiration pneumonitis (Mendelson's syndrome) is chemical injury of lung tissue secondary to aspiration of regurtitated gastric acid. [15] The syndrome was first described among pregnant patients [16] after the administration of anesthesia, though it can occur in any scenario where gastric contents are aspirated. [17]
If the foreign body does not cause a large degree of obstruction, patients may present with chronic cough, asymmetrical breath sounds on exam, or recurrent pneumonia of a specific lung lobe. [2] If the aspiration occurred weeks or even months ago, the object may lead to an obstructive pneumonia or even a lung abscess.
Depending on the type and amount of irritant gas inhaled, victims can experience symptoms ranging from minor respiratory discomfort to acute airway and lung injury and even death. A common response cascade to a variety of irritant gases includes inflammation , edema and epithelial sloughing , which if left untreated can result in scar formation ...
It is also used by breath-hold divers to increase their lung volumes. [5] Positive airway pressure is a mode of mechanical or artificial ventilation based on insufflation. [citation needed] Pump inhalers for asthmatics deliver aerosolized drugs into the lungs via the mouth. However, the insufflation by the pump is not adequate for delivery to ...

Fire breather’s pneumonia is caused by the entrance of hydrocarbon fuels into the bronchial tree, usually due to accidental aspiration or inhalation during a fire performance show. Fire breathing, or fire blowing, is the act of creating a plume of fire by blowing a mouthful of fuel in a fine mist (atomization) over a source of ignition. Fire ...
In rare cases, severe inflammation of lungs can occur. [7] Lungs auscultation may reveal abnormal breath sounds such as crackles or rhonchi, and chest imaging can show lung consolidations [3] and edema. [4] Decreased lung volumes, including a reduction of average 0.7 liters in forced expiratory volume in 1 second and vital capacity, is found on ...
