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.
Treatment varies depending on the cause of respiratory arrest. In many cases, it is necessary to establish an alternate airway and providing artificial ventilation that can include modes of mechanical ventilation. There are many ways to provide an airway and to deliver breathing support. The list below includes several options.
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]
This chart can help you compare their symptoms and onset times. It can be hard to determine if you have Covid, flu, or RSV as all three viruses circulate. This chart can help you compare their ...
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 ...
The array of symptoms typically seen in carbamate poisoning include both muscarinic and nicotinic symptoms. [1] Muscarinic receptor effects include: Bradycardia, or reduced heart rate; Bronchospasm, or tightening of the bronchioles of the lungs; Miosis, or constriction of the pupils; Vomiting and abdominal pain; Diarrhea; Excessive sweating and ...
Symptomatic treatment, supportive care, supportive therapy, or palliative treatment is any medical therapy of a disease that only affects its symptoms, not the underlying cause. It is usually aimed at reducing the signs and symptoms for the comfort and well-being of the patient, but it also may be useful in reducing organic consequences and ...
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 ...
