Figure 4.

Effects of fluid resuscitation on respiratory rate in the three groups. There were no differences in respiratory rate among the groups during the 120 min trial or the 8 h follow-up. Comparing respiratory rates in the same group, the respiratory rate at T8h was lower than that at T0 in the Sb group (*p < 0.05) only; no change of respiratory rate appeared in the Ns or Hs groups. Resuscitation by fluids did not change the respiratory rate of patients during the 120 min trial.
