CVP level measure in the first 24 hours of admission to ICU. a vs. CVP measurement within 3 hours; b vs. CVP measurement from 4 to 6 hours; c vs. CVP measurement from 7 to 12 hours; a two-tailed value of <0.05 was considered statistically significant. CVP = central venous pressure; MAP = mean arterial pressure; CI = cardiac index; Lac = lactic acid; MPP = the mean perfusion pressure; ICU = intensive care unit.
