Question

1. Asthma is a restrictive lung disorder that causes constriction and congestion of the pulmonary bronchioles. How would an asthma attack affect FVC

Answer 1

Answer:

by hyperinflation of lungs

Explanation:

Asthma is a disease of the lungs caused by inflammation and narrowing of the airways, thereby difficulting breath. Severe asthma disorders are associated with a significant decrease in the rate of maximal expiratory airflow and the reduction in the total volume expired, which is a value known as Forced Vital Capacity (FVC). In consequence, severe asthma events are correlated with the hyperinflation of the lungs and thus be a possible cause for the observed reduction in the FVC.
