Interpretations of spirometry results require comparison between an individual’s measured value and the reference value. If the FVC and the FEV1 are within 80% of the reference value, the results are considered normal. The normal value for the FEV1/FVC ratio is 70% (and 65% in persons older than age 65).

Understanding Spirometry - Normal, Obstructive vs Restrictive Spirometri mäter två nyckelfaktorer: expiratorisk tvingad vital kapacitet (FVC) och tvungen Normal-område.

It is calculated as 1.645 times the standard error of the estimate (SEE). FVC/FEV-1: Spirometry also takes these two scores and calculates your FVC/FEV-1 ratio. This tells you the percentage of your lung’s air space that you can exhale in one second. Normal results are 70% or more for adults under 65. FVC/FEV-1 ratios below normal help your doctor rate the severity of your lung condition: Mild lung condition: 60% to 69% Generally speaking, normal results often have an FVC and a FEV1 above 80 percent predicted with a FEV1/FVC ratio that is greater than 70 percent. While these predicted values may still seem confusing, we break down the spirometry test results even further below.

2020-03-25 · Normal spirometry values vary, but they generally are considered normal when the forced expiratory volume, or FEV1, is less than 80 percent of the predicted value. They are also considered normal when the forced vital capacity, or FVC, to FEV1 ratio is 0.7 or less, says Patient.

Spirometry is useful in distinguishing respiratory from cardiac disease as the cause of breathlessness and can be used to screen for Figure 1.

FVC. Peak flow. Examples of obstructed and restricted flow loops.

If the FVC is normal and the FEV1 or FEV1/FVC ratio are below normal, then this suggests you may have airway obstruction which includes lung diseases like asthma, COPD or bronchitis. A normal expiratory flow-volume loop has a triangular shape with it's top at the left. The inspiratory part of the loop is shaped like a half circle. The values of the parameters are higher than 80% of the predicted values, while the Tiffeneau index (FEV1/FVC*100) is higher than 70. The normal range is calculated by the spirometer based on your height, age, gender and ethnicity.
