艾烟对健康成年人血压、呼吸频率、心率、心电、血氧饱和度的影响

The Effect of Moxa Smoke on Blood Pressure,Respiratory Rate,Heart Rate,ECG and Oxygen Saturation of Healthy Adults

目的：研究艾烟对健康成年人的血压、呼吸频率、心率、心电ST段、血氧饱和度等各项生理指标的影响，为艾烟的安全性评价研究提供依据。方法：30名受试者随机分为试验组（艾烟诊室）20人，对照组（无烟诊室）10人，试验组艾烟浓度控制在9～12 mg/m3。使用超思MMED6000DP监护仪监测试验前、试验中、试验后每位受试者的血压、呼吸频率、心率、心电ST段、血氧饱和度，并进行统计分析比较。对试验组受试者艾烟环境中的舒适或不适主观感受进行调查。结果：试验组和对照组在试验前、试验中、试验后各项指标比较均无统计学意义。艾烟环境前后，试验组各项指标比较无统计学意义。试验组有7例出现不适症状，2例出现舒适症状。结论：艾烟（9～12 mg/m3）对人体的血压、呼吸频率、心率、心电ST段、血氧饱和度等各项常见生理指标无明显影响，表明一定浓度艾烟是相对安全的。较高浓度艾烟会使人产生不适感受，因此艾烟浓度需要适度控制。

Objective：To explore the effect of moxa smoke on blood pressure,respiratory rate,heart rate,ECG and oxygen saturation of healthy adults,and provide the basis for safety evaluation of moxa smoke.Methods：30 subjects were randomly divided into experimental group （n=20,moxa smoke clinic）and control group （n=20,non-smoke clinic）.The density of moxa smoke was limited between 9 to12mg/m3 .Chaosi MMED6000DP monitor was used to record each subject＇s blood pressure,respiratory rate,heart rate,ECG ST segment and oxygen saturation before,during and after the experiment.Meanwhile we investigated the experimental group whether they had any discomfort feelings or not.Results：All the experiment indicators of the experimental group and the control group,before,during,after the experiment,were not statistically different.In experimental group,7 patients had bad symptoms and two had comfortable feelings. Conclusion：The moxa smoke （9~12mg/m3 ）has no significant effect on healthy adults＇blood pressure,respiratory rate,heart rate,ECG ST segment,oxygen saturation,which proved certain density of moxa smoke is relatively safe.While moxa smoke of higher density will make people feel uncomfortable,so it needs to be appropriately controlled.
