Is a difficulty in breathing caused by a sudden constriction of the muscles in the walls of the bronchioles as occurs in asthma.
A narrowing or constriction of the bronchi that occurs during an asthma attack or from a severe allergic reaction.
Sudden constriction of breathing tubes.
A tightening of the bronchial muscles which causes the tubes to contract, as in asthma.
Spasm of the bronchi, causing them to narrow, making exhalation difficult and noisy; it is commonly associated with asthma and bronchitis.
An involuntary, rapid contraction of the bronchiole smooth muscle.
A narrowing and constriction of the muscles surrounding the airways, or bronchi, reducing the flow of air. Bronchospasm may be associated with asthma, inflammation caused by infection, chronic bronchitis, or exercise. Bronchospasm is generally treated with one of the bronchodilators, which relaxes smooth muscle and opens the airways to permit normal breathing.
Narrowing of bronchi by muscular contraction in response to some stimulus, as in asthma and bronchitis. The patient can usually inhale air into the lungs, but exhalation may require visible muscular effort and is accompanied by expiratory noises that are clearly audible or detectable with a stethoscope. The condition in which bronchospasm can be relieved by bronchodilator drugs is known as reversible obstructive airways disease and includes asthma; that in which bronchodilator drugs have no effect is irreversible obstructive airways disease and includes chronic bronchitis.
Muscular contraction of the bronchi (air passages) in the lung, causing narrowing. The cause is usually a stimulus, as in bronchitis and asthma. The result is that the patient can inhale air into the lungs but breathing out becomes difficult and requires muscular effort of the chest. Exhalation is accompanied by audible noises in the airways which can be detected with a stethoscope. Reversible obstructive airways disease can be relieved with a bronchodilator drug; if the bronchospasm cannot be relieved by drugs it is called irreversible.
An abnormal narrowing with partial obstruction of the lumen of the bronchi due to spasm of the peribronchial smooth muscle. Clinically this is accompanied by coughing and wheezing. Bronchospasm occurs in reactive airway diseases such as asthma and bronchitis. Treatment may include bronchodilators and corticosteroids.
Bronchospasm refers to the temporary constriction of the bronchi, which are the air passages leading to the lungs. It occurs due to the contraction of the muscles within the bronchial walls, inflammation of the bronchial lining, or a combination of both factors. The contraction may be triggered by the release of certain substances during an allergic reaction. As a result of narrowed airways, airflow is impeded, leading to symptoms such as wheezing or coughing.
The primary cause of bronchospasm is asthma, which accounts for the majority of cases. Other potential causes encompass respiratory infections, chronic obstructive pulmonary disease (COPD) characterized by lung inflammation and damage, anaphylactic shock (a severe and potentially life-threatening hypersensitivity reaction), or allergic reactions triggered by exposure to certain chemicals.
