WebNational Center for Biotechnology Information WebThe breathing reserve is calculated as the ratio of maximal voluntary ventilation (MVV) at rest to maximal exercise ventilation. Most healthy subjects achieve a maximal exercise ventilation of only 60% to 80% of the MVV at rest. One characteristic of chronic pulmonary disease is a maximal ventilation that approximates the individual's MVV.
