上节课我们向大家介绍了

非专业人员的基础生命支持

那么这节课向大家介绍

专业人员的基础生命支持

专业人员的基础生命支持

包括胸外按压和通气两大部分

在按压和通气这两部分中

按压的重要性要大于通气

当施救者一旦判断出

患者心跳停止后

应立即开始胸外按压

在这里再次强调

高质量的胸外按压

在CPR中的重要性

高质量的胸外按压包括

一 胸外按压的位置

位于胸骨下段的终点

二 按压的方向应该垂直于胸廓

三 按压的频率至少100次每分

按压的频率至少5厘米

四 按压后应充分回弹

按压与回弹的比例应有1:1

五 按压尽量不要被打断

如果因为操作而需要中断按压

中断的时间不应该超过10秒

每做五组或两分钟胸外按压后

应更换一名施救者

以避免因力量不足

而导致按压质量下降

关于通气

首先要做的是打开气道

打开气道的目的

在于降低气道由于生理弯曲

而造成的阻力

保证气体能够进出气道

打开气道的方法有很多种

包括常用的仰额抬颌法

抬举下颌法等等

在这里向大家介绍仰额抬颌法

仰额抬颌法的操作手法

是用一只手的小鱼际

下压患者的颚部

另一只手的十指和中指

向上方抬起患者的下颌支

使患者的头部后仰

患者的气道接近直线

以方便气体的进出

在开放气道时应注意

如果患者不能够排除颈椎损伤

应该为患者佩戴颈托

或用手法固定患者的头部

以避免在开放患者气道的过程中

损伤患者的脊髓

专业人员区别于非专业人员

进行心肺复苏之处

在于要为患者提供通气

通气的方法分为口对口人工通气

和简易呼吸器通气

现在专业人员常用的通气方法

是简易呼吸器通气

成人用简易呼吸器的气囊容量

在1500毫升左右

使用的时候用单手挤压气囊

1/3左右

每次供气约500到600毫升即可

按压与通气的比例为30比2

在进行球囊通气的时候

要注意避免过度通气

许多急救人员

急于恢复患者的自主心率

在进行CPR操作的时候

容易过快 过用力地按压球囊

像这样

要知道

我们在进行胸外按压的时候

心脏的射血量

只有正常的30%

这些血液不能满足生理需求

一旦给患者造成过度通气

会使通气血流比升高

流入脑组织的血流中

氧含量过高

过高的血氧

会导致脑组织血管收缩

进一步加重脑灌注不足

所以在进行球囊通气的时候

应注意按照

30比2的按压通气比率

每次通气500到600毫升就可以了
