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.
采用体力测定法对56例慢性支气管炎患者和46名健康受试者进行递增运动研究。比较了运动极限时的身体潜能、通气的定性和定量特征、血流动力学及气体交换情况。已证实，在疾病早期，运动时因支气管通畅性恶化会出现过度通气倾向，同时气体交换水平的通气效率显著降低。还发现能量活动程度与支气管通畅性密切相关。作者基于线性回归方程，利用外呼吸功能参数给出了确定工作适应性预后的实用建议。
