FEF, or Forced Expiratory Flow, is a measurement used to assess lung function. Essentially, it checks how well your lungs are working.
How FEF is Measured
The process for measuring FEF involves a specific breathing technique:
- Deep Inhalation: The person takes the deepest breath possible.
- Forced Exhalation: The person then blows the air out as forcefully and quickly as they can.
- Airflow Measurement: A machine measures the airflow, indicating how fast the person is exhaling. This measurement provides insights into the health and function of the lungs.
In essence, FEF helps doctors understand how efficiently air moves out of your lungs during a forced exhalation.
