What age does lung function peak?
What age does lung function peak?
Table 2. The lungs undergo a phase of growth and maturation during the first two decades of life and achieve maximal lung function around age 20 years in females and 25 years in males.
Does FVC change with age?
Both FEV1 and FVC decline with age, but the decline in FEV1 is greater (Figure 1). Thus, the FEV1/FVC ratio also declines with age. The FEV1/FVC ratio is useful in the diagnosis of obstructive lung diseases.
When to use normal or abnormal spirometry results?
Normal or abnormal results are evaluated differently between adults and children: For children ages 5 to 18: An abnormal FVC could be due to restrictive or obstructive lung disease, and other types of spirometry measurements are required to determine which type of lung disease is present.
How is spirometric lung function related to height?
There is no doubt that spirometric lung function is related to height and, in adults, both FEV 1 and FVC are known to decrease with age. However, in children, as a result of the growth process, age and height are highly correlated, thus some references have chosen to omit age from prediction models.
Which is the best reference for inter-preting spirometry?
Survey (NHANES III) reference is currently recommended for inter- preting spirometry results, but it is limited by the lack of subjects younger than 8 years and does not continuously model spirometry across all ages. Objectives: By collating pediatric data from other large-population surveys, we have investigated ways of developing reference ranges
What do you need to know about lung age?
Lung Age is a term referring to the age of lungs of human with regard to many factors such as smoking, air pollution, etc. It refers to the average age of a nonsmoker with a forced expiratory volume at 1 second (FEV1) equal to that of the person being tested. Lung age (Spirometry results) helps assess premature lung damage…

How old do you have to be to have a lung test?
The ability to reply to this post has been turned off. Lung age is just a way of putting the results of a spirometry test into simple understanderble terms (and to scare you into stopping smoking probably). I’m 46 with a lung age of 142. while I’m not as active as I would like life still goes on.
Why do they say lung age is Ove?
