问题肺动脉栓塞导致的休克哪项不正确

选项 A．可有意识突发不清 B．氧饱和度往往尚正常 C．一般有右心负荷增加表现 D．可无胸痛咳嗽的临床表现 E．PAWP往往降低

答案 B

解析：肺栓塞如导致休克，往往是主肺动脉病变，会出现通气血流比例失调而致氧饱和度低。

错误啦！

消息: [程序异常] : MISCONF Redis is configured to save RDB snapshots, but it's currently unable to persist to disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.
