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.
With emphysema the shortness of breath due to effective bronchoconstriction from excessive very thick mucus blockage (it is so thick that great difficulty is encountered in expelling it resulting in near exhaustion at times) can bring on panic attacks unless the individual expects this and has effectively learned pursed lip breathing to more quickly transfer oxygen to the blood via the damaged ...
In May 2013, the American Thoracic Society issued the first treatment guidelines for EIB, recommending use of "a short-acting β2-agonist before exercise in all patients with EIB. For patients who continue to have symptoms of EIB despite the administration of a short-acting β2-agonist before exercise, strong recommendations were made for a ...
Complications from respiratory compromise are increasing rapidly across the clinical spectrum, partly due to expanded use of opioids combined with the lack of standardized guidelines among medical specialties. While respiratory compromise creates problems that are often serious and potentially life-threatening, they may be prevented with the ...
Bronchial hyperresponsiveness (or other combinations with airway or hyperreactivity, BH used as a general abbreviation) [1] is a state characterised by easily triggered bronchospasm (contraction of the bronchioles or small airways). Bronchial hyperresponsiveness can be assessed with a bronchial challenge test.
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.
Guidelines recommend against the use of bronchodilators in children with bronchiolitis as evidence does not support a change in outcomes with such use. [ 9 ] [ 20 ] [ 46 ] [ 47 ] Additionally, there are adverse effects to the use of bronchodilators in children such as tachycardia and tremors , as well as adding increased cost to the medical visit.
While it is considered a relief or rescue medication, it can take a full hour to begin working. For this reason, it plays a secondary role in acute asthma treatment. Dry throat is the most common side effect. If the medication gets in contact with the eyes, it may cause blurred vision for a brief time.
