Figure 2

Relationship between oxygen extraction ratio with low and high tidal volume (TV) strategies. See text for details. Correlation between O2ER during high TV strategy and O2ER during low TV strategy: r = 0.68 (P = 0.003). Linear regression (solid line): O2ER during high TV strategy = 0.07 + O2ER during low TV strategy. Dotted line: identity line. O2ER: oxygen extraction ratio; TV: tidal volume.
