Pulmonary aspiration is the entry of solid or liquid material such as pharyngeal secretions, food, drink, or stomach contents from the oropharynx or gastrointestinal tract, into the trachea and lungs. [1] When pulmonary aspiration occurs during eating and drinking, the aspirated material is often colloquially referred to as "going down the ...
The trachea is the largest tube in the respiratory tract and consists of tracheal rings of hyaline cartilage. It branches off into two bronchial tubes, a left and a right main bronchus. The bronchi branch off into smaller sections inside the lungs, called bronchioles. These bronchioles give rise to the air sacs in the lungs called the alveoli. [10]
Figure A shows the location of the lungs and bronchial tubes. Figure B is an enlarged view of a normal bronchial tube. Figure C is an enlarged view of a bronchial tube with bronchitis. Specialty: Pulmonology: Symptoms: Cough with sputum, wheezing, shortness of breath, fever, chest discomfort [1] [2] Duration: Up to 6 weeks [3] Causes: Typically ...
Plastic bronchitis bronchial casts [80] Plastic bronchitis is a rarely found condition in which thickened secretions plug the bronchi. [81] [82] The plugs are rubbery or plastic-feeling (thus the name). The light-colored plugs take the branching shape of the bronchi that they fill, and are known as bronchial casts. [81]
Injuries to the tracheobronchial tree within the chest may occur due to penetrating forces such as gunshot wounds, but are more often the result of blunt trauma. [6] TBI due blunt forces usually results from high-energy impacts such as falls from height and motor vehicle accidents; the injury is rare in low-impact mechanisms. [2]
The bronchial circulation is the part of the systemic circulation that supplies nutrients and oxygen to the cells that constitute the lungs, as well as carrying waste products away from them. It is complementary to the pulmonary circulation that brings deoxygenated blood to the lungs and carries oxygenated blood away from them in order to ...
“After eating a big meal, you may not feel like you can ingest anything else, but sipping water afterward can make you feel better by keeping you hydrated,” says Shelley Balls, M.D.A., RDN ...
Asthma is a common pulmonary condition defined by chronic inflammation of respiratory tubes, tightening of respiratory smooth muscle, and episodes of bronchoconstriction. [1] The Centers for Disease Control and Prevention estimate that 1 in 11 children and 1 in 12 adults have asthma in the United States of America. [ 1 ]
