Question

When performing pulmonary function testing in a clinical setting, obtaining adequate results typically requires:

a) Single forced maneuver
b) Multiple forced maneuvers
c) Passive breathing
d) Valsalva maneuver

Answer 1

Adequate results from pulmonary function testing, such as spirometry, require multiple forced maneuvers to accurately diagnose lung conditions like fibrosis and asthma.

Step-by-step explanation:

When performing pulmonary function testing in a clinical setting, obtaining adequate results typically requires multiple forced maneuvers. These tests, such as spirometry, measure lung volumes like the forced expiratory volume (FEV) and the forced vital capacity (FVC). The FEV1/FVC ratio is particularly important in diagnosing lung diseases. For instance, if this ratio is high, it may indicate lung fibrosis, a condition where the lungs are stiff and less pliable. Conversely, a low ratio suggests resistance, characteristic of conditions like asthma. It's crucial in both cases to perform multiple maneuvers to get accurate measurements.
