Blood gas during the experiment.
| Time | M0 | M20 | M40 | M60 |
|---|---|---|---|---|
| pH | 7.1 ± 0.1 | 7.1 ± 0.2 | 7.2 ± 0.2 | 7.3 ± 0.1 * |
| PaO2 (mmHg) | 15 ± 4 | 126 ± 61 * | 70 ± 29 * | 68 ± 12 * |
| PaCO2 (mmHg) | 75 ± 17 | 62 ± 12 | 49 ± 11 * | 44 ± 8 * |
| HCO3 (mEq.L−1) | 23 ± 8 | 20 ± 5 | 22 ± 6 | 23 ± 7 |
Values are means ± SD. PaO2, arterial partial pressure of O2; PaCO2 arterial partial pressure of CO2; HCO3, bicarbonates. M0 represents the moment when mechanical ventilation was started; M60, the time at which the umbilical cord was clamped. * Significant difference accepted as p ≤ 0.05.
