Fig. 1From: Initial central venous pressure could be a prognostic marker for hemodynamic improvement of polymyxin B direct hemoperfusion: a retrospective cohort studyPatient flow diagram for this study. Among 112 patients who received PMX-DHP for septic shock, 70 patients met the requirements of our study but 42 patients were excluded for several reasons as follows: age, 2; reasons for admission to ICU, 13; vasopressors not used, 9; no record of CVP, 18. The 70 patients were the divided into two groups: low central venous pressure (CVP) (CVP <12 mmHg; n = 33) and high CVP (CVP ≧12 mmHg; n = 37)Back to article page
