Figure 2.

Linear correlation of Δ[Lac] to ΔVO2. The latter represents the difference in VO2 calculated using either SraO2 or SpaO2 in place of mixed venous SO2 in the Fick's Equation (Δ[Lac] mmol.L-1 = 0.0026 ΔVO2 ml.min-1 + 0.0975; r2 = 0.34; p < 0.0001). Standard error of the estimate 0.15 mmol.L-1.
