问题 术中判断心跳停止最可能的依据是
选项 A.大动脉搏动消失 B.立即观察瞳孔变化 C.数呼吸频率 D.用听诊器听心音 E.测血压
答案 A
解析 :颈动脉(或股动脉)搏动消失,即可诊断为心跳呼吸骤停而立即抢救。切不可反复看瞳孔、听心音、测血压、数脉搏而延误抢救时机。

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.
