Lung age estimates the age of your lungs from FEV1 spirometry, comparing actual function to predicted function for different ages. Used in smoking cessation — telling a smoker their lungs are 10 years older is more motivating than quoting FEV1%.
Guia passo a passo
- 1Predicted FEV1 by sex, age, height (Quanjer equations)
- 2Lung age: find the age at which predicted FEV1 equals actual FEV1
Exemplos resolvidos
Entrada
FEV1=2.8L · predicted for age 40 is 3.5L (matches 55-yr prediction)
Resultado
Lung age ≈ 55 (15 years older than actual)
