An inexpensive apparatus (airflometer) to assess lung function.

The Airflometer is presented as an inexpensive instrument suitable for lung function testing in general clinical practice. Utilizing the close correlation between the Airflometer (AFM) reading and the forced expiratory volume in 1 second (FEV1), we have produced a nomogram from which the AFM reading for normal males and females can be predicted.
