A health care proxy is a form of power of attorney concerning your health care decisions in the event that you can’t speak for yourself. It will be used infrequently but it is a necessary tool that you must have in order to protect yourself and your family.
If you become unconscious or cannot speak for yourself, a health care proxy gives someone that you trust the legal right to make medical decisions for you. It saves your family a lot of time and grief to have a person already named in a legal document able to makes medical decisions for you if tragedy strikes.
A health care proxy runs hand-in-hand with an advanced care directive (or living will) but may also be combined into one document. The health care proxy names a person to make your medical decisions if you can’t and the advanced care directive (or living will) gives that person some guidance as to what you would want done for you in terms of food and nutrition, heroic lifesaving measures, and other medical determinations on your behalf.
Medical personnel who are given a health care proxy that is drawn up in accordance with legal requirements must honor the decisions made by the agent (the person that you choose). And if you have discussed your preferences with your agent, they will carry out your wishes. You could also have a living will that will spell out your wishes. It takes the burden off your family of guessing who you would want to make those decisions and what those decisions should be.
In order for your health care proxy and living will to be useful, you need to give your agent a copy of the health care proxy to be available in case you can’t talk for yourself. You don’t do yourself any good if no one knows you have drawn up this document or can’t find it when you least expect to need it.
