title: [Ergospirometry in the diagnosis of disorders of the oxygen transport system in patients with chronic bronchitis].
abstract: Ergospirometry was used to carry out a study with the increasing exercise in 56 patients with chronic bronchitis and 46 healthy subjects. The limit physical potentialities, qualitative and quantitative characteristics of ventilation, hemodynamics, gas exchange at the height of the exercise were compared. It has been established that in the early disease stages, there was a tendency to hyperventilation during exercise in response to the deterioration of bronchial patency, which was accompanied by significant deterioration of the efficacy of ventilation with respect to the level of gas exchange attained. A close relationship has been discovered between the magnitude of energy activity and bronchial patency. The authors give practical recommendations for determining work fitness prognosis on the basis of the linear regression equation with the use of the parameters of external respiratory function.
