Functional patterns in chronic obstructive airway diseases and their significance for the clinical short time prognosis
Ab s t r a ct. 68 patients with acute exacerbation for their chronic obstructive airway disease were divided in three groups by means of the intrathoracic gas volume (IGV). The measured IGV was expressed in percent of an expected value (IGV % E), which was estimated for each measured total airway resistance (Rt}. In these three groups other lung functional patterns, clinical prognosis and relation to etiological factors were tested. While the mean R t showed no significant differences between the groups, we correlated a high value of IGV % E (_>125%, group I) with a high degree of substantial emphysema respectively high lost of lung elastic recoil, an indifferent value of IGV % E (91-124%, group If) with the prevalence of a functional emphysema, and a low value of IGV % E (
