... Questionnaire from 63 to 48 points (p = 0.028). Conclusion: LVR coil treatment in homogeneous patients improves hyperinflation, airway resistance, exercise capacity and quality of life with an acceptable safety profile. The benefit of LVR coil treatment is not limited to patients with heterogeneous emphysema...

... and compared with a number of sensitive tests for the detection of incipient bronchial obstruction: dynamic and static lung compliance (C L dyn, C L Stat); maximal expiratory flows at 50% and 25% (MEF 50% , MEF 25% ) of the forced vital capacity (FVC); closing volume (CV); airway resistance (Raw), and residual...

... states of respiratory mechanics i.e. resting tidal breathing at functional residual capacity (FRC) versus forced expiratory manoeuvre from total lung capacity to residual volume. The evaluation of airway resistance and forced expiratory volume at 1 s (FEV 1 ) may thus assist in the interpretation...

... added inspiratory resistive loading. We measured the ratio of forced expiratory volume in 1 s to forced vital capacity (FEV 1 /FVC) and airway resistance (R aw ) as indices of airway obstruction, and the ratio of functional residual capacity to total lung capacity (FRC/TLC) as an index of hyperinflation...

...J. Green; S.T. Chiang; Y.C. Yang; G.M. Shiao; S.C.

...W.K.R. Barnikol; K. Diether The classical quantity to characterize the state of the human bronchial system is the airway resistance (R aw ). We have developed a new method for measuring the anatomical dead space (VD) and we have shown that the bronchial system may be characterized by the anatomical...
