Indices of the Ventilation Apparatus in Cases of Chronic Pneumonia, and Their Dependence of the Degree of Respiratory Failure (Pokazateli Apparata Ventilyatsii pri Khronicheskoi Pnevmonii v Zavisimosti ot Stepeni Dykhatelnoi Nedostatochnosti)
Abstract
The report is devoted to an analysis of the results of a complicated and dynamic examination of the ventilation apparatus in eighty-five patients having chronic pneumonia. The patients were examined both in a state of rest after performing an assigned physical task, and after inhaling ephedrine. The conclusions drawn from these studies are as follows: (1) There is a relationship between the functional condition of the ventilation apparatus and the clinically determined severity of respiratory failure: definite functional disturbances in a series of indices (MVL, VCL, pneumotachometric data, FVCL, frequency and depth of respiration) correspond to the degree of respiratory failure. (2) In chronic pneumonia, even during the early stages of development, there are disturbances of the bronchial permeability. (3) Dyspnea is not the first sign of respiratory failure. Even before it occurs, some functional disorders of the ventilation apparatus become manifest in chronic pneumonia patients (reduction of MVL, reduction of velocity of air stream in forced respiration, VCL and unevenness of ventilation).
