Figure 3From: Vascular pedicle width in acute lung injury: correlation with intravascular pressures and ability to discriminate fluid statusCorrelation of VPW with PAOP and CVP. (a) demonstrates that VPW correlates moderately well with PAOP (VPW = 57 + 0.9*PAOP; r = 0.41; P < 0.001). (b) demonstrates the weak correlation between VPW and CVP (VPW = 66.4 + 0.45*CVP; r = 0.21; P = 0.001).Back to article page
