搶救危重病人时,在給氧过程中,有时氧气一时輸不出去,当将流量开关关閉时,潮化器里的水就倒流至流量表內,这时如不及时排除,直接影响病人的及时用氧和影响流量的不准确,現根据我院实际工作中摸索出来的排除方法,現介紹如下,供同志們参考。一、倒流原因:常为橡皮管有折叠或插入病人鼻腔的导管部分有粘液堵塞。这时气体放不出去,将流量开关关閉时,在潮化瓶內暫时造成負压,而至使水产
When emergency patients are rescued, oxygen may not be able to be delivered for a time during the oxygen supply. When the flow switch is turned off, the water in the turbidizer flows back to the flow meter. If it is not eliminated in time, it directly affects the patient. The inaccuracy of the timely use of oxygen and the impact on the flow rate is now based on the exclusion method that has been explored in the actual work of our hospital and is now introduced as follows for reference by comrades. First, the reasons for the backflow: often there is a mucous plug in the catheter tube where the rubber tube is folded or inserted into the patient’s nasal cavity. At this time, the gas cannot be released. When the flow switch is turned off, the negative pressure is temporarily caused in the tidal flask, and the aquatic product can be produced.
