Analysis of EVLWI
| Variable | Survivors (n = 58) | Nonsurvivors (n = 65) | p value |
|---|---|---|---|
| EVLWImin (mL/kg) | 7.3 ± 2.7 | 8.5 ± 4.1 | 0.059 |
| EVLWImax (mL/kg) | 11.7 ± 4.3 | 13.7 ± 5.9 | 0.041 |
| EVLWImean (mL/kg) | 9.2 ± 3.3 | 10.7 ± 4.6 | 0.043 |
| Day EVLWImax (day) | 2.4 ± 1.4 | 3.1 ± 2.2 | 0.026 |
| ΔEVLWI (mL/kg) | −1.3 ± 3.5 | 2.1 ± 5.0 | <0.001 |
| ΔmaxEVLWI (mL/kg) | −3.3 ± 3.8 | 2.5 ± 5.3 | <0.001 |
EVLWImin, minimal EVLWI during ICU stay; EVLWImax, maximal EVLWI during ICU stay; EVLWImean, mean EVLWI during ICU stay; ΔEVLWI, difference between first and last extravascular lung water index; ΔmaxEVLWI, maximal difference between extravascular lung water index.
