| O2 Sat (%) | 96.5±0.5 | 96.5±0.5 | 96.6±0.3 | 96.2±0.3 |
| pH | 7.34±0.01 | 7.32±0.02 | 7.38±0.01 | 7.37±0.01 |
| Standard Base Excess (mmol/l) | −3.7±1.1 | −2.2±0.7 | −2.6±0.4 | −1.7±1.1 |
Values are mean ± SEM (n = 7, 10, 6 and 7 in Groups I, IIa., IIb. and IIc., respectively). No significant difference was found between the experimental groups.
