Okay let's wrap up this video series.
A bronchospasm is a sudden tightening or constriction
of smooth muscles of the walls of the bronchioles.
That makes it diffickut for a person to breathe.
Remember, bronchi, bronchioles, okay.
Smooth muscle is part of the airway and the muscarinic
receptors control bronchoconstriction, and mucus.
Okay, so anticholinergic medications block the
bronchoconstricton and effects of the muscarinic receptors.
So if a patient is taking anticholinergic medication,
remember that's an antagonist to the cholinergic receptors.
So you have less of the bronchoconstrictive
effects, and that mucus.
Beta-2 agonist on the other
hand, they activate beta-2 receptors
whose job it is to cause
bronchodilation of the airways.
Now bronchoconstriction can be treated with
bronchodilators and antocholinergics or steroids
but remember you want a short acting
beta-2 agoinist if in the case of an emergency.
Thank you for watching our video today.
