Linear relationship between PPVs under the VT of 6, 8 and 10 ml/kg after volume expansion. PPV6: pulse pressure variation at a VT of 6 ml/kg; PPV8: pulse pressure variation at a VT of 8 ml/kg; PPV10: pulse pressure variation at a VT of 10 ml/kg. Equation (a) represented the linear correlation between PPV6 and PPV 8. Equation (b) represented the linear correlation between PPV6 and PPV 10. Equation (c) represented the linear correlation between PPV8 and PPV10.
