A Medical Power of Attorney is a legal document that allows an individual, known as the principal, to appoint someone else, called the agent or attorney-in-fact, to make healthcare decisions on their behalf. This arrangement is particularly important if the principal becomes unable to communicate their wishes due to illness or injury. The agent is responsible for ensuring that the principal's medical preferences are honored. This document typically outlines the specific powers granted to the agent, which may include decisions about treatments, surgeries, and end-of-life care. It is essential for individuals to discuss their healthcare wishes with their chosen agent to ensure that their values and preferences are respected in critical situations.
