Our experience with the early detection of small respiratory diseases.

Abstract

In order to establish which method of examining pulmonic is appropriate for early diagnosis of small respiratory airway diseases, we made examinations of several groups by using different apparatuses and different tests. The first group consisted of 1517 young men. We examined them by MMFR and FEV1 and established that MMFR 25-75/FVC had discovered double number with lessened values than FEV1. In the fourth group a hundred men, aged 50, were examined by plethysmography and measurement of closing volume and we established the results of MEF 25 and MEF 50 as the best, as well as IGV while Rt and Rs did not show sufficient susceptibility for small respiratory airway diseases, as for closing volume it showed increasing for all, especially for smokers.
