Question

During pulmonary testing, the flow volume loop of an individual who has asthma and is experiencing airway obstruction will likely be:

a) Narrowed and elongated
b) Wide and shortened
c) Normal
d) Inverted

Answer 1

The flow volume loop of an individual with asthma and airway obstruction will likely be narrowed and elongated.

Step-by-step explanation:

The flow volume loop of an individual with asthma and airway obstruction will likely be narrowed and elongated (option a).

Asthma is a chronic inflammatory disease of the airways that can lead to airway constriction and obstruction. During pulmonary testing, a flow volume loop is used to measure the amount of air a person can inhale and exhale at different lung volumes.

In individuals with asthma and airway obstruction, the flow volume loop will show a decreased peak flow rate and a flattened expiratory phase. This indicates a narrowed and elongated loop compared to individuals without airway obstruction.
