密闭式静脉输液是农村社区卫生服务中心或服务站常用的输液方式,为药液加入密闭式输液瓶内采用一次性输液管输液。近年来,笔者在对服务对象进行输液治疗过程中,通过常规巡视与观察,发现输液管在周围环境温差增大的情况下,输液管内壁渐... 密闭式静脉输液是农村社区卫生服务中心或服务站常用的输液方式,为药液加入密闭式输液瓶内采用一次性输液管输液。近年来,笔者在对服务对象进行输液治疗过程中,通过常规巡视与观察,发现输液管在周围环境温差增大的情况下,输液管内壁渐产生气泡甚至气段,极易发生空气栓塞现象。 展开更多

Climate change is the main problem of mankind, especially because of it's increasing speed and by specialists' forecast the situation will become worse. Climatic changes are correlated with the degradation of biosphere. It is a question of saving life on authors planet. The authors should begin taking strong measures, else Earth has a chance to repeat the destiny of Mars and Venus, as some scientists are afraid of. So reasoning like "When will it be and will it be at all" is for lazy, careless and selfish people. Now, because of the industrial emission of greenhouse gases, the temperature of the atmosphere is growing, the climate is changing: sudden temperature differences, snowfalls where it used to be impossible, thickness of arctic ice decrease is about 40% (a great ice-hole has been found on the north pole), repetition of droughts has increased in 8 times, power of hurricanes-2 times, increased power of floods. This is the result of lack of foresight, over-materialism and greediness, unwillingness to see the consequences because of the momentary advantages. How it is possible to trap CO2, SO2 and other gases? Commercially gas purification at thermoelectric power stations, ferrous and non-ferrous metallurgy plants, cement and chemical plants is being made with filters and cyclones that trap solid parts, and using different absorptive and adsorptive methods. Unfortunately at present there is no effective method of COE trapping. 展开更多
