The American Medical Association (AMA) recommends the use of an advance directive called a "Living Will" as a type of advance medical directive.
Through the event that they are unable to articulate their choices, people can declare their preferences for medical care through a living will, which is a legal document. Usually, it specifies the precise medical procedures or therapies that a person would or would not want in particular circumstances, such as life-supporting techniques, resuscitation, or the use of artificial feeding and hydration.
When a person is unable to make their own medical care decisions, a living will serves as a guidance for family members and healthcare professionals.

What is an advance medical directive?
An advance medical directive is a legal document in which a person specifies what actions should be taken for their health if they are no longer capable of making decisions for themselves due to illness or incapacity. Advance directives may also be referred to as living wills, durable power of attorney for health care, or healthcare proxy, depending on the state. In the United States, every state has its own set of laws regarding advance directives.
They were initially designed to protect the right of terminally ill individuals to refuse lifesaving medical treatments. Now, advance directives are used to protect the patient's right to accept or refuse medical treatment.
What is the Durable Power of Attorney for Health Care?
The Durable Power of Attorney for Health Care is a type of advance directive in which an individual designates someone to make decisions about their medical care if they become incapacitated. This person is referred to as the "healthcare agent" or "healthcare proxy." This document grants the designated person the authority to make medical decisions on behalf of the patient if they are unable to do so themselves.
It may include instructions for the proxy or agent to make decisions, but it isn't a requirement.
What is the American Medical Association (AMA)?
