It can very quickly restore normal respiration to a person whose breathing has slowed or stopped as a result of overdosing with heroin or prescription opioid pain medications.

对于因过量服用海洛因或处方阿片类止痛药而导致呼吸减慢或停止的人，它可以非常迅速地恢复正常呼吸。

A moment later the soft in-out of normal respiration, which I've listened to my whole life (mostly without being aware of it, thank God) , has been replaced by an unpleasant shloop-shloop-shloop sound.

过了一会，我一辈子都在听的自己那轻柔的呼吸声（绝大多数时间我对此毫无知觉，感谢上帝）突然被一种令人不快的呼——呼——呼——声所取代。
