About the Lung Age Calculator:
  • 1. Lung age refers to the 'age' of your lungs. Through lung function tests, you can directly reflect the aging and health status of your lungs.
  • 2. Generally, the 'age' of this organ should match your actual age, and its performance and lifespan should also be consistent with reality.
  • 3. Male lung age = (0.0414 × height - 2.190 - FEV1) / 0.0244
  • 4. Female lung age = (0.0342 × height - 1.578 - FEV1) / 0.0255
  • 5. FEV1 in 1 second (L): Male: 3.18±0.12L; Female: 2.31±0.05L.
