Key facts

Expired minute volume/Carbon dioxide production during exercise
Volume.expired per minute/Carbon dioxide production^W exercise
The ventilatory efficiency slope is calculated as the ratio of minute ventilation to carbon dioxide production. It is correlated with disease severity for various cardiopulmonary conditions, including pediatric pulmonary hypertension and adult heart failure. PMID24144928
