Figure 3. Changes (compared with preinfusion values) in (A) heart rate and (B) mean arterial blood pressure during and after infusion of 5% human serum albumin (HSA;[circle, open] all doses combined) or 5% recombinant human hemoglobin (rHb1.1;[round bullet, filled] 0.015 g/kg;[square, filled] 0.075 g/kg;[lozenge, open] 0.11 g/kg;[up triangle, filled] 0.15 g/kg). The rate of infusion varied from 0.8–1.9 h (see text). *P < 0.05 versus HSA at the same time point. #P < 0.05 versus preinfusion values for the same group. Data are means +/- SE.
