Abstract:Background: Currently, excess ventilation has been grounded under the relationship between minute-ventilation/carbon dioxide output ( V ˙ E − V ˙ CO 2). Alternatively, a new approach for ventilatory efficiency ( η E V ˙) has been published. Objective: Our main hypothesis is that comparatively low levels of η E V ˙ between chronic heart failure (CHF) and chronic obstructive pulmonary disease (COPD) are attainable for a similar level of maximum and submaximal aerobic performance, conversely to l… Show more
