12. A useful way to express FEV1 is as a percentage of the forced vital capacity (FVC). Using the FEV1 and FVC valuesfrom the data grid, calculate the FEV1 (%) by dividing the FEV1 volume by the FVC volume (in this case, the VC is equal tothe FVC) and multiply by 100%. Enter the FEV1 (%) for an airway radius of 3.00 mm in the field below and then click Submitto record your answer in thelab report.
