Bronchoconstriction is defined as the narrowing of the airways in the lungs (bronchi and bronchioles). Air flow in air passages can get restricted in three ways: [3] a spasmodic state of the smooth muscles in bronchi and bronchioles; an inflammation in the middle layers of the bronchi and bronchioles; excessive production of mucus.
It is possible for cardiogenic pulmonary edema to occur together with cardiogenic shock, in which the cardiac output is insufficient to sustain an adequate blood pressure to the lungs. This can be treated with inotropic agents or by intra-aortic balloon pump , but this is regarded as temporary treatment while the underlying cause is addressed ...
Bronchitis is inflammation of the bronchi (large and medium-sized airways) in the lungs that causes coughing. Bronchitis usually begins as an infection in the nose, ears, throat, or sinuses. The infection then makes its way down to the bronchi. Symptoms include coughing up sputum, wheezing, shortness of breath, and chest pain.
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 ...
YOU KNOW FROM high school that your lungs bring in oxygen and move it to the blood (inhale) while taking carbon dioxide out of the blood (exhale). Not as well-known: Your lungs are also ...
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 ...
Hypoxia: Low blood oxygen can cause confusion and unconsciousness. It can also lead to cardiac arrest if not fixed quickly. [1] Aspiration Pneumonia: If particles enter the lungs, it can cause lung infections. This can happen from aspirating a foreign body. [8]
These airways carry oxygen to the bronchioles inside the lungs. Inflammation of the bronchii and bronchioles can cause them to swell up, which could lead to an asthma attack. This results in wheezing, tightness of the chest, and severe difficulty in breathing. There are different types of asthma that affect the functions of the bronchial tubes.
