You can put any wishes you have for medical care in your living will. You can instruct that certain types of care are given, or instruct that certain types of care are not given. For example, you can instruct that you should be put on a ventilator if needed, or instruct that you should never be put on a ventilator.
Your state’s form will request your input about various types of care, including:
Life-prolonging medical care. These treatments include: blood transfusions, CPR, diagnostic tests, dialyses, administration of drugs, use of a respirator, and surgery.
Food and water. Some permanently unconscious patients can live for a very long time if given intravenous food and water. Some people want this, some don’t.
Palliative care. Palliative care is care given to reduce pain when one chooses to forego life-prolonging treatments.
