What medical decisions can my healthcare agent make that I should discuss in advance?

A healthcare agent named in your medical power of attorney steps in when you can't communicate, making decisions such as consenting to or refusing treatments, choosing doctors and facilities, and deciding about surgeries, life support, and pain management. Because they'll interpret your wishes in situations you can't foresee, have an honest conversation covering your views on life-sustaining treatment, feeding tubes, resuscitation, organ donation, and what quality of life matters to you. A living will documents some of these preferences, but no document covers every scenario, so your agent's understanding of your values is essential. Pick someone who can stay calm under pressure and advocate for you even against other relatives' objections. Revisit the conversation as your health and views change over time.
