Association of time-related increased lung weights (LW) and hemoglobin (Hb) in blood to analyze interrelationships that could explain fluid-shifts from blood into the lung. The degree of hemoconcentration was predicted based on the gain of lung weights (LWincrease) [mg] of phosgene-exposed rats relative to the lung weights (LWc) and hemoglobin (Hbc) [g/L] of pooled control rats. The blood volume was calculated using the following relationship: bloodvol [mL] = body weight [g] × 6.4 [%] [142]. As an approximation, increased lung weights were considered equal to increased lung water content. Data points represent means ± SD (three rats per group and time point)
