Measurements included lung volumes, maximal expiratory flow-volume curves, and closing volumes. Miners, when compared with controls, showed a marked decline in maximal expiratory flow at mid-vital capacity (V 50%) over the 4-year period which took place without significant change in the 1-second forced expiratory volume (FEV1). Frequency dependence of dynamic compliance (Cdyn) in association with an increased upstream airways resistance (Rus), and also loss of lung elastic recoil (PL(St)) which were present at the time of the original study led to similar declines in V 50%. An abnormally elevated closing capacity expressed as a percentage of total lung capacity (CC/TLC)% was found in 9 miners (53%) and none of the controls. Closing volume as a percentage of vital capacity (CV/VC)% was abnormal in 4 miners (23.5)% and no controls. Measurement of closing volume did not relate well to the variety of mechanical abnormality present on the original study; namely, loss of recoil or small airways obstruction.

Group A showed decrease in FIV1.0, PIFR and VI50 when compared with corresponding expiratory parameters. Group B only showed a decrease in PIFR compared with PEFR. In all patients the high flow area near TLC in expiratory V/V curves was replaced by a flat flow pattern, extending variably into lower lung volumes. Predominant inspiratory flow reduction was present in Group A. Usually the normal expiratory plateau (IVPF curves) was absent even at very low lung volumes (about 25% VC) in the 8 patients studied (Group A, B, C). In Group B, inspiratory and expiratory resistances (IVPF curves) were similar up to about 50-60 cm H2O Palv; above this level inspiratory resistance was higher. The flow-pressure pattern (IVPF curves) of a normal subject with a relatively low resistance added at the mouth (9 mm i.d.) was very close to that of the resistance alone throughout inspiration. Above 60 cm H2O Palv expiratory resistance appeared to be lower, as in Group B. Calculated pressure drop due to convective acceleration across the resistance coincides with its pressure-flow relationship. These results do not support the hypothesis of inspiratory reduction in tracheal caliber as a contributing cause to inspiratory flow decrease. The difference PEFR-PIFR at highest Palv was inversely related to the degree of obstruction. Consequently, flow-volume curves of moderate sublaryngeal lesions may show disproportionate reductions in VI (like Group A) despite its fixed nature. Results obtained in six patients submitted to surgical treatment are discussed.</p>","PeriodicalId":75638,"journal":{"name":"Bulletin de physio-pathologie respiratoire","volume":"11 6","pages":"803-22"},"PeriodicalIF":0.0,"publicationDate":"1975-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12405043","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
