Are there any potential threats from bronchoconstriction?

Are there any potential threats from bronchoconstriction?

Stop breathing: Bronchoconstriction, or narrowing of the airways due to swelling and/or spasm, decreases airflow into the lungs, and increases the effort needed to get that air in. This combination of stresses lowers the oxygen level, and if severe enough, a person can become weak, confused, collapse from exhaustion or even stop breathing altogether. This is how people can even die from an asthma attack. ...Read more

Does bronchoconstriction help protect the body from infection?

What does the doctor mean by acute, severe bronchoconstriction?

What does the doctor mean by acute, severe bronchoconstriction?

Tightened airways: Bronchoconstriction is narrowing of the air passages between the windpipe and the air sacs of the lungs, and is generally caused by swelling and spasm, which can be caused by infection, asthma, allergies, chemical irritation (smoke, smog or fumes), or a combination of factors. Acute means that a problem started suddenly or is only there for a short while (as opposed to chronic, all the time). ...Read more

How does the parasympathetic nervous system affect bronchoconstriction?

How does the parasympathetic nervous system affect bronchoconstriction?

Pulmonary functions: Both the sympathetic and parasympathetic nerves affect both broncho- dilatation and brochoconstriction, and are secondarily affected by several drugs. A beta blocker may cause constriction, epinephrine may result in bronchodilatation. ...Read more

What are some of the cells and inflammatory mediators involved in non-asthmatic exercise induced bronchoconstriction?

Why is breathing in during inspiration not affected by bronchoconstriction (asthma or copd)?

Pressure.: Long story...essentially, the pressure pushing upon the airways with expiration causes the airways to close upon themselves, causing air trapping which is one of the hallmarks of COPD and the other obstructive lung diseases. ...Read more
