FEV1 is the volume of air that can forcibly be blown out in first 1-second, after full inspiration. [13] Average values for FEV1 in healthy people depend mainly on sex and age, according to the diagram. Values of between 80% and 120% of the average value are considered normal. [14]
Predicted normal values can be calculated online and depend on age, sex, height, and ethnicity as well as the research study that they are based upon. A derived value of FEV1% is FEV1% predicted, which is defined as FEV1% of the patient divided by the average FEV1% in the population for any person of similar age, sex, and body composition.
English: Normal values for Forced Vital Capacity (FVC), Forced Expiratory Volume in 1 Second (FEV1) and Forced Expiratory Flow 25–75% (FEF25–75%). Y-axis is expressed in Litres for FVC and FEV1, and in Litres/second for FEF25–75%.
Average resting respiratory rates by age are: [11] [self-published source] [12] birth to 6 weeks: 30–40 breaths per minute; 6 months: 25–40 breaths per minute; 3 years: 20–30 breaths per minute; 6 years: 18–25 breaths per minute; 10 years: 17–23 breaths per minute; Adults: 15–18 breaths per minute; 50 years: 18-25 breaths per minute ...
The difference between the highest values of two FVCs need to be within 5% or 150 mL. When the FVC is less than 1.0 L, the difference between the highest two values must be within 100 mL. Lastly, the difference between the two highest values of FEV1 should also be within 150 mL. The highest FVC and FEV1 may be used from each different test.
A normal adult has a vital capacity between 3 and 5 litres. [3] A human's vital capacity depends on age, sex, height, mass, and possibly ethnicity. [ 4 ] However, the dependence on ethnicity is poorly understood or defined, as it was first established by studying black slaves in the 19th century [ 5 ] and may be the result of conflation with ...
