Calculated OCQ and COQ curves. The graph shows the calculated OCQ (cO2/cCO2) and COQ (cCO2/cO2) values according to the corresponding O2 and CO2 concentration in the off gas. Assumed is a RQ of 1 meaning for every respired portion of O2 a equivalent portion of CO2 is produced. The curve progression indicates best sensitivity for OCQ at concentrations of O2 and CO2 on the left side of the graph which usually occur at low respiratory activity.
