[Computer-assisted measurement of mean transit time and partial mean transit time].
A pulmonary function measurement system was developed. This system was made up by Fleisch flow transducer, the pressure transducer and 486 computer. It can calculate and print out the mean transmitted time (MTT) the partial mean transmitted time (MTTp) and the routine pulmonary function automatically.
