搶救傷員進(jìn)行人工呼吸的方法有哪幾種，具體是怎樣操
人工呼吸是搶救傷員的一種急救措施：凡是由于觸電、溺水、缺氧窒息、二氧化碳及瓦斯窒息或一氧化碳中毒而處于假死狀態(tài)的傷員，均可對(duì)其施行人工呼吸急救措施。施行人工呼吸前，首先將患者抬到新鮮風(fēng)流較溫暖的地方．使其躺在擔(dān)架上或衣服上，迅速解開其上衣和腰帶，脫掉膠靴；取出口中、鼻孔中之堵塞物，并網(wǎng)棉被或醫(yī)子將身體蓋好，以免受涼；檢查有無內(nèi)外傷，以便決定采用何種人工呼吸法。常用的人工呼吸法有三種：（1）口對(duì)口呼...
澳大利亞煤礦安全培訓(xùn)——永良公司專業(yè)培訓(xùn)
項(xiàng)目簡介：隨著國家改革開放步伐的加快，我國的各行各業(yè)都處在一個(gè)經(jīng)濟(jì)騰飛的階段，在經(jīng)濟(jì)發(fā)展的同時(shí)也暴露出很多問題。煤礦行業(yè)的安全問題就是比較突出的一個(gè)方面。目前我國煤炭行業(yè)存在很多安全問題，百萬噸煤炭的傷亡事故率居高不下，給國家財(cái)產(chǎn)和人民生命安全造成嚴(yán)重?fù)p失。澳大利亞的煤礦企業(yè)有著優(yōu)良的安全紀(jì)錄和經(jīng)驗(yàn)，連續(xù)四年百萬噸煤的傷亡事故率為零，如此優(yōu)良的安全紀(jì)錄是值得我們關(guān)注的。結(jié)合澳大利亞煤礦公司的先進(jìn)管...
