C.反比通气

D.同步间歇指令通气

E.双水平气道正压通气

答案

参考答案：C

解析：慢阻肺患者其呼气阻力大于吸气阻力，而反比通气是使吸气时间延长，适逢其反，且易引起气压伤，故不适用。其余通气方式均能主要克服吸气阻力，故可用。

We often hear people talking about a generation gap (代沟). The name is new,but the idea is old. Young people and their parents don’t understand each other. The world has always kept changing. During the second century after Christ a wise man said, “Bury me on my face because in a little while everything will be turned upside down.”  There has always been a gap between generations, but more people talk about it now. Old Mr. Ellis thinks he understands what has happened. “When I was a boy, I thought the world was a beautiful place. My life was very pleasant. But when I was older, I learned about people who were treated badly, people who didn’t have enough to eat. I wanted to help them, and I married a girl who wanted to help them, too. We went to meetings and talked a lot, but it didn’t seem to make much difference. ”“Our children grew up in a world at war. They didn’t know when the fighting would stop. They wanted their children to have nice clothes and toys. They didn’t want to think about the future. They thought nothing could be done about it.” “Now I have grandchildren, and they have their own ideas. They are trying to make the world better. They are trying to help other people. They’re making people listen to them. I am proud of their generation.”
