| name | Expired minute volume/Carbon dioxide production during exercise | ||
| description | 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. PMID: 24144928 | ||

| property | VRto = Volume Ratio | ||
| time | Pt = Point in time: To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements. | ||

| scale | Qn = Quantitative: The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range. The test result value may optionally contain a relational operator from the set {<=, <, >, >=}. Valid values for a quantitative test are of the form "7", "-7", "7.4", "-7.4", "7.8912", "0.125", "<10", "<10.15", ">12000", 1-10, 1:256 | ||
