原始语种摘要: The lungs and heart are irrevocably linked in their oxygen (O2) and carbon dioxide (CO2) transport functions. Functional impairment of the lungs often affects heart function and vice versa . The steepness with which ventilation ( V ′E) rises with respect to CO2 production ( V ′CO2) ( i.e. the V ′E/ V ′CO2 slope) is a measure of ventilatory efficiency and can be used to identify an abnormal ventilatory response to exercise. The V ′E/ V ′CO2 slope is a prognostic marker in several chronic cardiopulmonary diseases independent of other exercise-related variables such as peak O2 uptake ( V ′O2). The V ′E/ V...
