  • Title: [Variability of respiratory function tests 9 weeks observation (author's transl)].
    Author: Pham QT, Mur JM, Gimenez M, Mastrangelo G, Henquel JC.

    Abstract:
    42 normal male subjects from 19 to 27 years, are examined in conditions of field studies once a week for 9 weeks. At each session are measured: flow volume curves with determination of vital capacity (VC), forced expiratory volume in one second (FEV 1.0), peak flow (V peak), flows at 0.75, 0.50, 0.25 of VC (V 0.75 VC, V 0.50 VC, V 0.25 VC). Single breath nitrogen test, with determination of slope of phase III (delta N2/liter) and closing volume/vital capacity (CV/VC). Single breath and steady state tests with carbon monoxide. Variability of functional pulmonary indices in this study is greater than those observed in the literature during shorter period of term. Some indices varied significantly during these 9 weeks of observation like V 0.25 CV, indices of transfer factor of CO and CV/VC (according to repetition of test or meteorologic factors?). Relevance of studying variations during a relatively long period, is pointed out in interpretation of results observed in prospective studies.
