Ventilatory equivalent for carbon dioxide --W exercise

VEqCO2 W exercise

Definition

  • The ventilatory equivalent for carbon dioxide (VEqCO2) is the ratio of ventilation to carbon dioxide production at a point in time. It is an alternative measurement to the slope of ventilation to carbon dioxide production as calculated for the duration of exercise. VEqCO2 and time to lowest VEqCO2 may be predictors of mortality in patients with heart failure. [PMID: 22619715]
