Deciding about treatments that prolong life

Life Sustaining Treatments

Sometimes after injury or a long illness, the primary organs of the body no longer work properly without support. Your doctor may tell you that these organs will not repair themselves.

Medical care to prolong life can keep you alive when these organs stop working well.

  • The treatments extend your life but do not cure your illness.
  • These are called life-sustaining treatments.

Treatments to extend life can include the use of machines. This equipment does the work of the body organ. Examples include:

  • A machine to help breathing (ventilator)
  • A machine to help your kidneys (dialysis)
  • A tube into your stomach to provide food (nasogastric or gastrostomy tube)
  • A tube into your vein to provide fluids and medicines (also called intravenous tube)
  • A tube or mask to supply oxygen

Making the Decision for Yourself

If you are near the end of your life or you have an illness that will not improve, you can choose what kind of treatment you want to receive.

You should know that removing the life support equipment does not end life: the illness or the injury is the cause of the end of life.

  • Talk to your health care providers to learn about life-support care you are receiving or may need in the future.
  • Learn about the treatments and how they would benefit you.
  • Learn about side effects or problems the treatments might cause.
  • Think about the quality of life you value.
  • Ask your doctor what happens if life support care is stopped or you choose not to start a treatment.
  • Find out if you will have more pain or discomfort if you stop life support care.

These can be hard choices for you and those who are close to you. There is no hard and fast rule about what you may choose. People's opinions and choices often change over time.

How to Make Your Wishes Known

Talk to your health care providers about your choices. Other steps you can take to make sure your wishes are followed are:

As your life or health changes, you may also change your health care decisions. You can change or cancel an advanced care directive at any time. 

Making the Decision for a Loved One

You may serve as a health care agent or proxy for someone else. In that role you may have to make the decision to start or remove life support machines. It is a very hard decision to make.

If you need to make a decision about stopping treatment for a loved one:

  • Talk to their doctor.
  • Review the goals of their medical care.
  • Weigh the benefits and burdens of treatments on your loved one’s health.
  • Think about your loved one’s wishes and values.
  • Seek advice from other health care professionals, such as a social worker.
  • Seek advice from your loved one’s family members.
