Questions and Answers

What does the Forced Vital Capacity (FVC) measure in spirometry?

The maximum amount of air a person can exhale forcefully after taking a deep breath (correct)
The maximum speed of exhalation
The amount of air forcibly exhaled in the first second during the FVC test
The rate at which a person can inhale air

What does the Forced Expiratory Volume in 1 second (FEV1) measure in spirometry?

The maximum speed of exhalation
The maximum amount of air a person can exhale forcefully after taking a deep breath
The amount of air forcibly exhaled in the first second during the FVC test (correct)
