This device is used to measure Peak Expiratory Flow (PEF) and Forced Expiratory Volume in 1-second (FEV1) in both children and adults. PEF is the fastest speed air can be blown out of the lungs after inhalation. FEV1 measures the volume after exhaling in 1-second. Peak Flow (PEF) and Forced Expiratory Volume in 1-second (FEV1) measurements can tell how well lungs are breathing by monitoring airflow.
