2组患者PaO2、OI、气道平台压和气道阻力比较
Comparison of PaO2, OI, APP, and AR at different time points between the two groups (Mean±SD)
| Time point | Experiment group (n=62) | Control group (n=62) | |||||||
| PaO2 (mmHg) | OI (mmHg) | APP (cmH2O) | AR (cmH2O/LS) | PaO2 (mmHg) | OI (mmHg) | APP (cmH2O) | AR (cmH2O/LS) | ||
| Compare to Control group, *P < 0.05. PaO2: Arterial oxygen partial pressure; OI: Oxygenation index; APP: Airway plateau pressure; AR: Airway resistance. | |||||||||
