Question

Which of the following measures and evaluates a patient's lung capacity and volume?

1) Spirometry
2) Electrocardiogram
3) MRI
4) Blood test

Answer 1

Spirometry is used to measure lung volumes and capacities, including the forced expiratory volume (FEV) and forced vital capacity (FVC). These measurements can help diagnose respiratory diseases like asthma and fibrosis.

Step-by-step explanation:

Lung volumes and capacities are measured using a technique called spirometry. Spirometry measures the forced expiratory volume (FEV) and forced vital capacity (FVC) to evaluate a patient's lung capacity and volume. These measurements can be used to diagnose respiratory diseases such as asthma, emphysema, and fibrosis. The ratio of FEV1 to FVC can indicate the presence of lung diseases, with a high ratio indicating lung fibrosis and a low ratio indicating asthma.
