Bronchospasm or a bronchial spasm is 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. It causes difficulty in breathing which ranges from mild to severe.
Affected are preschool and school-age children with a male predominance. [2] In one study, the median age was 6 years (range 2–13.2 years). [1] It has been estimated that BACM has an incidence of 2.69 cases per 100,000 children (<18 years) during epidemic seasons and 0.23 cases during non-epidemic seasons. [3]
While a different cause, this has very similar symptoms, namely the immunological reaction involving release of inflammatory mediators. Inhalation of allergens in sensitized subjects develops into bronchoconstriction within 10 minutes, reaches a maximum within 30 minutes, and usually resolves itself within one to three hours. In some subjects ...
Exercise-induced bronchoconstriction can be difficult to diagnose clinically given the lack of specific symptoms [2] and frequent misinterpretation as manifestations of vigorous exercise. There are many mimics that present with similar symptoms, such as vocal cord dysfunction, cardiac arrhythmias, cardiomyopathies, and gastroesophageal reflux ...
Children who suffer from frequent respiratory infections prior to the age of six are at higher risk of developing asthma, particularly if they have a parent with the condition. However, persons of any age can have asthma triggered by colds and other respiratory infections even though their normal stimuli might be from another category (e.g ...
“Writing, coloring, eating, dressing, brushing teeth, cooking, typing, drawing, video games, piano and skiing are among the many things I do. I live on my own and have had to learn how to make ...
Lower airway: may occur from bronchospasm, drowning, or airspace filling disorders (e.g. pneumonia, pulmonary edema, pulmonary hemorrhage). [7] Obstructive conditions of the lower airway, including severe asthma or COPD episodes, can also lead to respiratory arrest. During these episodes, known as exacerbations, airway resistance is increased ...
Bronchospasm, or tightening of the bronchioles of the lungs; Miosis, or constriction of the pupils; Vomiting and abdominal pain; Diarrhea; Excessive sweating and salivation; Bronchospasm is a potential life threat, especially when combined with nicotinic effects on the respiratory muscles. Bradycardia can be life-threatening in people with ...
