Bronchoconstriction is the constriction of the airways in the lungs due to the tightening of surrounding smooth muscle, with consequent coughing, wheezing, and shortness of breath.
Actually, bronchoconstriction affects the airways in a person's lungs. You can think of airways like straws or tubes. They let air flow in and out so you can breathe. These airways have muscles, but not the kind you flex! ...
Bronchoconstriction
An airflow limitation due to contraction of smooth airway muscle.

Bronchoconstriction
Adenosine is a respiratory stimulant (probably through activation of carotid body chemoreceptors) and intravenous administration in man has been shown to increase minute ventilation (Ve) and reduce arterial PCO2 causing ...
Bronchoconstriction. Tightening of the muscles around the airways, narrowing the airways and making breathing difficult.
Inflammation. Swelling and irritation in the airways of the lungs common in asthma.
Bronchoconstriction may result from an antigen-antibody reaction, eg, in some forms of occupational asthma; from pharmacologic mechanisms (in byssinosis), ...
Bronchoconstriction (bands of muscle lining the airways tighten up)
Anyone can have asthma, including infants and adolescents. The tendency to develop asthma is often inherited; in other words, asthma can run in families.
Narrowed airways or bronchoconstriction (bands of muscle lining the airways tighten up) ...
bronchodilator therapy — including a methylxanthine (theophylline or aminophylline) and a beta2-adrenergic agonist (albuterol or terbutaline) — to decrease bronchoconstriction, reduce bronchial airway edema, ...
Gastric acid causes a chemical burn of the airways and lung leading to rapid bronchoconstriction, atelectasis, edema, and alveolar hemorrhage.
A person may have asthma symptoms that become worse with exercise (more common) or may have only exercise-induced bronchoconstriction, without symptoms at other times.
Magnesium supplements may reduce the bronchoconstriction in asthma by relaxing the muscle around the bronchial tubes. Intravenous solutions containing magnesium and other nutrients have been used successfully to break acute asthma attacks.
A symptom complex associated with carcinoid tumour and characterised by attacks of severe flushing of the skin, diarrhoeal watery stools, bronchoconstriction, sudden drops in blood pressure, oedema, and ascites.
Airway (bronchial) irritation leading to narrowing of the airways (bronchoconstriction) or airway spasms (bronchospasm)
Bloodshot eyes
Increased heart rate and blood pressure
Pharyngitis, sinusitis, bronchitis, and asthma in heavy users ...
Evidence from contemporary clinical studies does not support this use, although black haw's activity as a smooth muscle relaxant could theoretically relieve bronchoconstriction.
Doctors and asthma specialists recognize that asthma has two main components: airway inflammation and acute bronchoconstriction (constriction of the airways).
Jones CO, Quereshi S, Rona RJ, Chinn S. Exercise-induced bronchoconstriction by ethnicity and presence of asthma in British 9 year olds. Thorax 1996; 51: 1134-1136.
Bronchial Provocation Test (breathe in certain substances to determine if the airways react to them)
Exercise-Induced Bronchoconstriction Test (exercise for a short period of time to determine if the airways react to exercise) ...
Beta-adrenergic receptor agonists (Beta-agonists) - Beta-agonists can be considered bronchodilators, as these drugs relax airway smooth muscle, and block the release of substances that cause bronchoconstriction, or narrowing of your lungs, ...
Individuals may become light-headed or rarely may faint during the test. In individuals with asthma, the tests may trigger bronchoconstriction that requires treatment. Individuals with severe lung disease may become exhausted by the testing.
formed by platelets, basophils, neutrophils, monocytes, and macrophages. It is a potent platelet aggregating agent and inducer of systemic anaphylactic symptoms, including hypotension, thrombocytopenia, neutropenia, and bronchoconstriction.
Numerous trials have documented the efficacy of ephedrine in the management of asthmatic bronchoconstriction and hypotension.
The diagnosis of carcinoid syndrome (a syndrome associated with flushing, diarrhea, bronchoconstriction, cardiac valvular lesions, and telangiectasia) is aided by demonstrating elevated 24-hour urinary 5-hydroxyindoleacetic acid levels.
Sulfite sensitivity reactions range from mild to severe and may include skin, respiratory, or gastrointestinal signs and symptoms. Bronchoconstriction with wheezing is the most common sensitivity response in asthmatics.
