Table 6 Predictive capabilities of computed tomography-based estimation of central venous pressure

From: Computed tomography to estimate cardiac preload and extravascular lung water. A retrospective analysis in critically ill patients

  CVP CT (R1) vs. CVP 95% CI lower 95% CI upper   CVP CT (R2) vs. CVP 95% CI lower 95% CI upper
Sensitivity 36% 17% 55% Sensitivity 32% 14% 50%
Specificity 80% 45% > 99% Specificity 100% 49% 100%
PPV 90% 71% > 99% PPV 100% 63% 100%
NPV 20% 3% 38% NPV 23% 5% 40%
  1. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and 95% confidence intervals (95% CI) for computed tomography (CT)-based estimations of central venous pressure (CVP CT) with regard to measured elevation of central venous pressure (CVP; CVP > 9 mmHg) are shown. CVP CT is separately shown for radiologist 1 (R1) and radiologist 2 (R2).
