the temporary narrowing of the airways in the lungs, either as a result of muscle contraction or inflammation; may be caused by asthma, infection, lung disease, or an allergic reaction
n. narrowing of bronchi by muscular contraction in response to some stimulus, as in asthma and bronchitis.
Spasm of lung bronchioles
Sudden constriction of the airways, or bronchoconstriction.
Contraction of the muscle in the walls of the bronchi.
Sudden constriction of the airways, resulting in difficulty with breathing. May require treatment with albuterol, bagging, and may cause desaturation and bradycardia until the episode resolves. Most common in infants who have been on a ventilator for some time, or who have chronic lung disease.
a spasm of the bronchi that makes exhalation difficult and noisy; associated with asthma and bronchitis
Acute airflow limitation due to contraction of airway smooth muscle.
The tightening of the muscle bands that surround the airways, causing the airways to narrow
contraction of the muscles surrounding the airways in the lungs.
Muscles closing down around the bronchial tubes, making the airways smaller.
Acute constriction of the bronchial tubes.
an involuntary contraction of the bronchial tubes, which may lead to breath difficulty.
Sudden contraction of the bronchi (one of the symptoms of bronchial asthma).
the sudden tightening of the bands of muscle that surround the airways, causing the airways to become narrower. Bronchospasm may result in wheezing.
Bronchospasm results when the bands of muscles around the airway (the bronchus) tighten, and limit the flow of air into and out of the lungs.
Sudden narrowing of the bronchial tubes which may be the result of a severe allergic reaction.
Intermittent violent contraction of the air passages of the lungs
Tightening of the muscles surrounding the bronchial tubes.
Narrowing of the airways due to constriction or squeezing of the surrounding muscles. It may also be aggravated by airway inflammation (redness, swelling and mucous secretions).
sudden involuntary contraction of the smooth muscles surrounding the bronchial tubes
Bronchial contraction in asthma.
Spasm of the bronchi, as in what happens during an asthma attack
A condition in which the muscles in the walls of the airways narrow or constrict causing difficulty breathing, coughing, and distress.
An abnormal contraction of the smooth muscle of the bronchi, resulting in acute narrowing and obstruction
Bronchospasm is a difficulty in breathing caused by a sudden constriction of the muscles in the walls of the bronchioles. It is caused by the release (degranulation) of substances from mast cells or basophils under the influence of anaphylatoxins.
