Apart from these, there is another important aspect of the spirometry result the FEV1/ FVC ratio. This number represents the percent of the lung size (FVC) that can be exhaled in one FEV1/FVC ratio. Doctors often analyze the FVC and FEV1 separately, and then calculate your FEV1/FVC ratio. The FEV1/FVC ratio is a number that represents the percentage of your lung capacity you 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). When compared to the reference value, a lower measured value corresponds to a more severe lung abnormality. Look at the predicted FEV1/FVC Ratio value.

What I don't understand is what units of measure were used to get the 2.15. I'm looking to buy a peak flow meter and the low meter ranges from 50-390 liters per minute. But I don't know how to convert my FVC of 2.91 to liters per minute because I don't know the units Spirometri betyder ordagrant att mäta andningen.
