| PaO (mmHg) | 239.10±104.65 | 223.82±88.69 | 0.433 |
| PaCO (mmHg) | 56.36±11.29 | 63.10±12.44* | |
| Pondus Hydrogenii | 7.33±0.61 | 7.29±0.06* | |

| Remifentanil (ml) | 5.41±2.43 | 5.24±2.99 | 0.759 |
| Adverse events | |||
| Intraoperation hypoxemia, n (%) | 3 (6.0) | 7 (14.0) | 0.318 |
| Intraoperation severe hypercapnia, n (%) | 1 (2.0) | 5 (10.0) | 0.204 |
| Post-operation hypoxemia, n (%) | 1 (2.0) | 2 (4.0) | 1.000 |
| Chemosis, n (%) | 0 (0.0) | 1 (2.0) | 1.000 |
| Delayed recovery, n (%) | 0 (0.0) | 1 (2.0) | 1.000 |
| Transfer to ICU, n (%) | 1 (2.0) | 2 (4.0) | 1.000 |
| Data are expressed as mean±standard deviation or as numbers and percentages. * Statistically significant compared with group W, Group W – Wei nasal jet tube group; Group M – endoscopic face mask group; Propofol: 10 mg·ml; Remifentanil: 40 μg·ml. PaO – arterial partial oxygen pressure; PaCO – arterial partial pressure of carbon dioxide; ICU – Intensive Care Unit. Intra-operation severe hypercapnia: Intra-operation PaCO ≥80 mmHg. | |||
