摘要
目的:研究分析高原高空及坑洞内施工现场长管道吸氧的效果。方法:在海拔约3 600、4 200、4 800 m的施工现场,各随机选取高原高空及坑洞作业者40名(高空及坑洞作业者各20名),吸氧前先测血氧饱和度3次,计算出平均值,再用50 m长管道,连接40 L氧气瓶以10、5、2.5 MPa压力,4 L/min的氧流量吸氧3 min后测量血氧饱和度3次,每次间隔1 min,计算出平均值,并进行对比分析。结果:在高原不同海拔高度的高空及坑洞内用长管道、以不同供氧压力、相同氧流量吸氧后血氧饱和度都显著提高,有统计学意义(P<0.01)。结论:高原高空及坑洞内施工现场长管道吸氧能显著提高血氧饱和度,改善缺氧,是解决高原高空及坑洞内作业缺氧的一种简单、易行、安全、有效的方法。
Objective：To study the effect of oxygen inhalation by using a long pipeline in the construction sites above the ground and in the potholes in the plateau.Methods： Forty subjects（20 aerial personals and 20 pit operators） were admitted for each group at the altitude of 3 600 m,4 200 m or 4 800 m.The blood oxygen saturation was determined for 3 times before oxygen inhalation and the average value was calculated.The oxygen was inhaled through a 50-metre-long pipeline connected to a 40-litre-volume oxygen bomb with the pressure of 2.5,5 or 10 MPa.The blood oxygen saturation was tested again after oxygen inhalation（4 L/min） for 3 times at an interval of one minute,the average value was calculated,and the contrastive analysis was carried out.Results： The blood oxygen saturation in subjects above the ground or in the potholes was significantly improved after long-pipeline oxygen inhalation with the different oxygen pressure and the same oxygen flow rate（P0.01）.Conclusion： The long-pipeline oxygen inhalation at the high-altitude construction sites above the ground or in the potholes could increase the blood oxygen saturation and improve hypoxia,which may be a simple,safe and effective method for the treatment of hypoxia in people working at the construction sites above the ground or in the potholes in the plateau.
