| 目的：探讨不同体位对严重肥胖者血氧饱和度的影响。方法：16 名平均体重指数(BMI)为40± 5 肥胖者和16 名年龄匹配的
正常体重者被纳入研究。分别在不同体外下(坐位、仰卧位、侧卧位)对所有参与者进行动脉血气监测。结果：肥胖者于坐位时动脉
PaO2为75± 4 mmHg，PaCO2为37± 3 mmHg；仰卧位时动脉PaO2为62± 5 mmHg，PaCO2为47± 5 mmHg；侧卧位时PaO2为
73± 3 mmHg，PaCO2为39± 2 mmHg；而正常体重者无明显变化。结论：严重肥胖者于平卧位时更容易出现低氧及高碳酸血症。 |

| Objective:To investigate the effect of different positions on the oxygen saturation in subjects with severe obesity.Methods:Eight obese subjects (OS) with a mean body mass index (BMI) of 40± 5 kg/m2 and Eight age-matched normal-weight control
subjects (CS) were enrolled in the study. Under different positions (sitting, supine and lateral positions ), all participants arterial blood gas
were be monitored.Results:Obese subjects when supine had a significantly less value of PaO2 and a more severe hypercapnia. In sitting
postures , PaO2was 75 ± 4 mmHg, PaCO2 was 37 ± 3 mmHg; In supine postures, PaO2was 62 ± 5 mmHg, PaCO2 was 47 ± 5 mmHg;
In lateral postures, PaO2 was 73 ± 3 mmHg, PaCO2 was 39 ± 2 mmHg; while no significant changes in the normal weight.Conclusion:Patients with severe obesity were more prone to have hypoxia and hypercapnia in the supine position. |
