A written statement detailing a person’s desires regarding future medical treatment in circumstances in which they are no longer able to express informed consent, especially an advance directive.
The time may come when a person can no longer make decisions for his / her own future. In such event if their physical and/or mental condition should deteriorate to such an extent that there is no reasonable prospect of their recovery from physical illness or impairment which is expected to cause them severe distress or to render them incapable of rational existence, a request can be made that the person be allowed to die.
This request can further direct that:
No systems be used in order to keep the person alive in circumstances where, but for the use of such systems, he / she would have died;
That the person be given whatever quantity of drugs are required to keep him / her free from pain or distress even if the moment of death is hastened thereby.
The person may or may not consent to any form of tube feeding.
