Figure 2From: Extravascular lung water in patients with severe sepsis: a prospective cohort studyScatter plot showing the relationship between (a) oxygenation (arterial oxygen tension [PaO2]/inspired fractional oxygen [FiO2] ratio) and extravascular lung water (EVLW) in all patients (R2 by linear regression = 0.27; P < 0.001), and (b) between minimum PaO2/FiO2 ratio and maximum EVLW in nonsurvivors (R2 = 0.60; P = 0.005).Back to article page
