FIG. 4.

Vital sign differences between groups. Comparison of mean vital signs and arterial blood gases between groups and across time. (A) Heart rate. (B) MAP, mean arterial blood pressure. (C) pH. (D) PaCO₂, partial pressure of CO₂. (E) SpO₂, pulse oximetry. (F) Temperature. Injured animals are shown by dashed line, sham animals by solid line. Horizontal lines indicate statistical significance between time points for each group with a p value of ≤0.05. Error bars indicate standard error of the mean.
