| Overall (n = 19) | Routine intraoperative arterial pressure management (n = 9) | Personalized intraoperative arterial pressure management (n = 10) | P-value | |
|---|---|---|---|---|
| Average intraoperative mitoPO2, mmHg | 39 (30 to 50) | 46 (30 to 51) | 38 (31 to 44) | 0.653 |
| Lowest intraoperative mitoPO2, mmHg | 7 (5 to 20) | 14 (6 to 22) | 5 (4 to 7) | 0.072 |
| Lowest intraoperative 5-min average mitoPO2, mmHg | 9 (7 to 26) | 17 (8 to 24) | 9 (5 to 23) | 0.390 |
| Percentage of surgical time with mitoPO2 < 50 mmHg, % | 81 (48 to 90) | 85 (52 to 93) | 78 (52 to 87) | 0.772 |
| Percentage of surgical time with mitoPO2 < 40 mmHg, % | 43 (21 to 73) | 35 (20 to 73) | 46 (29 to 73) | 0.810 |
| Percentage of surgical time with mitoPO2 < 30 mmHg, % | 28 (7 to 55) | 23 (7 to 45) | 35 (10 to 56) | 0.596 |
