Bronchospasm refers to a sudden constriction of the bronchial wall muscles.
It is caused by the release (degranulation) of substances from mast cells or basophils under the influence of anaphylatoxins.
It can be precipitated in many situations
- certain forms of pulmonary edema
- allergic reactions, including anaphylaxis
- certain allergic hypersensitivity states
- non-selective beta blockers
Treatment and prognosis
Its debilitating effects on breathing can range from very mild to severe. Treatment is usually with beta adrenergic agonists.
