现场应急救护程序d和r分别代表什么

现场应急救护程序d和r分别代表什么,第1张

现场应急救护程序d和r分别代表的是危险评估和检查伤病者反应。

急救是为了维持生命、防止伤病恶化、促进伤病恢复。而掌握“DRABC”这种简单又高效的急救方式,对于当事人和现场施救人员来说尤为重要。那么,这5个字母,分别代表的意思是:

1、D,是danger,即危险评估。当他人梁裤族需要救助时,施救者首先要判断救助行为是否会给自己带来危险,如在高速路上发现车祸,应先在前后各50米的范围内设置明显路障,再去查看车祸现场。

2、R,是response,即检查伤病者反应。当发现有纯告人需要救助时,应首先拨打120或其他电话呼救专业人员,同时观察救助者的反应。

3、A,是airway,即打开气道。去除口鼻异物、压前额、抬下颌,确保气道畅通。

4、B,是breath,即人工呼吸。用5至10秒钟,观察伤病者是否仍有自主呼吸。如无自主呼吸,高声呼橡弊救,并施行人工呼吸。

5、C,是dirculation,即胸外按压,恢复血液循环。

现场应急救护的原则

1、先复后固的原则

遇有心跳、呼吸骤停又有骨折者,应首先用口对口呼吸和胸外按压等技术使心、肺、脑复苏,直至心跳呼吸恢复后,再进行骨折固定。

2、先止后包的原则

遇有大出血又有创口者时,首先立即用指压、止血带或药物等方法止血,接着再消毒,并对创口进行包扎。

3、先重后轻的原则

指遇有垂危的和较轻的伤病员时,应优先抢救危重者,后抢救较轻的伤病员。

意思是“读和写”。

read :

英语单词,在汉语中有多种译法和解释,同时又是计算机语言函数和命令,用在不没虚租同的位置有不同的译法、解释及作用,应视情而定。

音标:[ri:d]

汉译:读

例子:

I want to read a book . ——我想读一本书。

The sign reads "No Smoking" . ——那个标牌写着"禁止吸烟"。

and:

And是英语中一个普通的枯兆连词,然而and并非只作并列连词用,它还具有一些不太常见的表达方式和意义,应根据上下文的特殊环境,作出判断才能准确理解其用法和意思。

音标:[ənd]

汉译:和

例子:

Peter dipped his whole head under, hat and all.——彼得连同帽子把整个头都浸在水里。

He jumped into the water, clothes and all.——他和衣跳进水里。

write:

write是一个英语单词,也是Unix命令行程誉渣序和内建指令。

音标:[raɪt]

汉译:写

例子:

He would write if you would answer. ——如果你回信的话,他就写信。

Please write your name and address in print.——姓名和地址请用印刷体书写。
