Based on lung function tests, high FEV1 values indicates good lung function whereas low FEV1 values indicates impaired lung function.
Lung function tests or pulmonary function tests are noninvasive tests performed to test how well the lungs are functioning.
The lung's primary function in gaseous exchange.
Thus, lung function tests determine how well the lungs perform gaseous exchange.
One parameter of lung function is Forced expiratory volume, FEV1.
Forced expiratory volume calculates the amount of air that a person can force out of their lungs in 1 second.
High FEV1 values indicates good lung function whereas low FEV1 values indicates impaired lung function.
