Mechanisms affecting exercise ventilatory inefficiency-airflow obstruction relationship in male patients with chronic obstructive pulmonary disease

Abstract Background Exercise ventilatory inefficiency is usually defined as high ventilation ( V ̇ E $$ \dot{\mathrm{V}}\mathrm{E} $$ ) versus low CO2 output ( V ̇ CO 2 $$ \dot{\mathrm{V}}\mathrm{CO}2 $$ ). The inefficiency may be lowered when airflow obstruction is severe because V ̇ E $$ \dot{\mat...
