If your loved one doesn't have an advance directive (also known as a living will,) you should help him prepare one immediately.

如果你深爱的人没有一份事前指示(也被称作遗嘱)，你应该立刻帮他准备一份。

An advance directive is a legal document that states what type of treatment you want - or don't want - in case you become physically unable to communicate.

一个预先声明是一份针对当您万一在生理上不能沟通的时候您希望或者不希望获得的治疗方式的法律文件。

If you have not completed an advance directive and become incapacitated, your doctor and family would have to agree on decisions about life-sustaining treatment.

如果您没有完成预先声明并归为无效，您的医生和家人须就生命支持治疗达成一致意见。
