WebApr 8, 2024 · For example, your FEV1 could be 80% of your predicted value. FEV1 values define the degree of obstruction: FEV1 greater than 80% of predicted = normal FEV1 65% to 79% of predicted = mild obstruction FEV1 50% to 64% of predicted = moderate obstruction FEV1 less than 50% of predicted = severe obstruction WebThis peak flow calculator helps you estimate the predicted maximum speed of expiration according to age, gender and height and check if your measured value is around it. You … programs mechanical engineers use
