Intergroup differences in pulmonary oxygenation.
| Group | T0 | T3 | T4 | |
|---|---|---|---|---|
| PaO2 (mmHg) | A | 79.8 ± 8.6 | 334.2 ± 53.1 | 310.6 ± 43.6b |
| B | 79.1 ± 10.6 | 316.0 ± 45.2 | 237.8 ± 40.4 | |
| PaCO2 (mmHg) | A | 40.7 ± 3.5 | 40.3 ± 2.1 | 41.7 ± 3.2 |
| B | 41.5 ± 2.8 | 40.9 ± 3.0 | 40.8 ± 3.0 | |
| pH | A | 7.41 ± 0.03 | 7.40 ± 0.03 | 7.39 ± 0.03 |
| B | 7.41 ± 0.02 | 7.40 ± 0.03 | 7.39 ± 0.05 |
Values are expressed as mean ± SD for continuous variables and two independent samples t-test is used for inter-group comparisons.
Group A is the experimental group; Group B is the control group.
Two independent samples t-test bp < 0.01, Group A vs. Group B.
PaO2, Arterial Partial Oxygen Pressure; PaCO2, Arterial Partial Carbon Dioxide Pressure; T0, after entering the operating room; T3, 20 min after the application of optimal PEEP; T4, at the end of one-lung ventilation.
