Unfortunately, sometimes later in life we reach a situation where we can not make sound medical decisions for ourselves. For these situations, Oklahoma has a document named the Advanced Directive for Health Care.
Here is part of the description from the Office of the Oklahoma State Attorney General's website:
"The Advance Directive for Health Care can be used to ensure your wishes are followed if you later become incapacitated and incapable of making an informed decision regarding your health care. If you signed a Directive to Physicians or other Advance Directive for Health Care under Oklahoma law prior to 2006, it is recommended that you complete the new Advance Directive because of additional options under the current law."
The Oklahoma Bar Association also describes what an Advanced Directive is on this page.
