References 1999;20:809–22. Different spirographic and flow volume curves are shown in Figure 2.11 It is important to understand that the amount exhaled during the first second is a constant fraction of the FVC, regardless of lung size. The percentage is based on “predicted normal values,” which are the expected results for someone your age, height, weight, gender, and race. GLI Spirometry Normal Values. The test session is finished when the difference between the two largest FVC measurements and between the two largest FEV1 measurements is within 0.2 L. If both criteria are not met after three maneuvers, the test should not be interpreted. 20. Click Calculate to calculate the predicted values. 8.

Culver BH. 69/No. 4. 0000225622 00000 n That means you will be required to know the normal ranges in order to select the correct answer. Hubert H, These are the three factors accounted in the estimation: ■ Age is used as factor in the calculation as VC increases during the 20s and 30s and then follows a steady decrease towards the 50s.
