问题 A.恶性高热 B.Ⅱ°房室传导阻滞 C.肺栓塞 D.中度贫血 E.强直性脊柱炎 使呼气末二氧化碳浓度显著增高的是
选项
答案 A 
解析 :恶性高热时,体内二氧化碳产量显著增高导致经肺排出显著增多;而肺栓塞时,肺动脉血中二氧化碳与肺泡的交换显著减少,导致经肺排出也显著减少。

错误信息

  • 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.
