Deciding to Stop Life Support: What Families Should Know
The short answer: when someone cannot speak for themselves, the decision to stop life support falls to the person they chose in writing, or, if they did not choose anyone, to the relative state law puts first, usually a spouse, then adult children. Your job is not to decide what you want. It is to say what they would have wanted, based on what you know of them. In US medical ethics there is no ethical difference between stopping a treatment that is no longer helping and never starting it. When life support is stopped, care does not stop: the team turns to keeping the person comfortable, and the family can usually be there. Death can come within minutes, or take hours or days, and occasionally the person lives on for longer than anyone expected.
Nothing on this page is medical advice for your situation. The people with the facts are the doctors and nurses caring for your family member. This page is about what families wish they had known when they walked into that meeting.
Who Decides
If they wrote it down. An advance directive (sometimes called a living will) says what treatment the person wanted. A health care power of attorney, or health care proxy, names who decides for them. If either exists, find it and give a copy to the team. The named person decides, even if other relatives disagree.
If they had a POLST. Some seriously ill people sign a POLST (some states use another name, such as MOLST), a medical order that travels with them and tells emergency staff and hospitals what treatment they want. It carries a lot of weight.
If there is nothing in writing. Most states have a default order of who can decide: typically a spouse, then adult children, then parents, then adult siblings, with some states adding other relatives or a close friend. The hospital's social worker or case manager can tell you who counts in your state. Where several people share the same level, for example three adult children, the team usually looks for agreement.
What You Are Being Asked
This is the part that families most often get wrong, out of love.
You are not being asked whether you are ready to let them go. Nobody ever is. You are being asked to be their voice: what would they choose, if they could sit up for five minutes and hear what the doctors are telling you?
Things that help you answer:
- What they said. "Don't keep me on machines." "I want everything done." "If I can't recognize my grandkids, let me go." Even offhand remarks count.
- How they lived. What they could not bear. What made life worth it to them.
- Their faith. Most religious traditions accept stopping treatment that only prolongs dying, but views differ, especially on artificial nutrition. If faith mattered to them, ask their clergy or the hospital chaplain.
When you genuinely cannot tell what they would want, the standard shifts to their best interests: what gives them the most benefit and the least suffering.
Questions to Ask the Medical Team
Ask for a family meeting with the doctor in charge, not just updates from whoever is on shift. Bring a notebook, or ask if you may record it. Good questions:
- What is happening, in plain words? What is the illness or injury, and what is the treatment doing?
- What is the best realistic outcome? Not the best possible one. If they survive, what would their life look like: awake? at home? able to talk, eat, breathe on their own?
- How sure are you? What would make you more or less sure, and how long would it take to know?
- What happens if we continue? And what happens if we stop?
- Could we try for a set period? Some teams offer a time-limited trial: continue treatment for a defined number of days, then meet again to decide based on whether the person is improving.
- Can we see the palliative care team? Palliative care specialists are experts in comfort and in these conversations. Asking for them is not giving up.
You can ask for a second opinion. If you disagree with the team, or the family cannot agree among itself, most hospitals have an ethics committee or ethics consultation service. Ask the nurse or social worker how to reach it.
What Happens When Life Support Is Stopped
Families who knew what to expect often say it helped. The details vary, but usually:
You choose a time, within reason. Families often wait for a relative to arrive, or for a chaplain or imam or rabbi to come. Ask how long you can reasonably wait.
The room is changed. Monitors and alarms are often turned off or silenced. Tubes and equipment that are no longer needed may be removed. Many units let you bring music, photos, a favorite blanket, and let more visitors in than usual.
Comfort medicines are given. Before and after the ventilator or other support is removed, the team gives medicines to prevent breathlessness, pain and distress, often an opioid such as morphine and sometimes a sedative. The aim is comfort. Palliative care guidance is clear that, given this way, they ease distress without shortening life; the underlying illness is what causes death. The last days explains this in more detail.
Breathing changes. After a breathing tube is removed, breathing may become irregular, with long pauses, or noisy from secretions in the throat. This is common, and usually more distressing for the family than for the person. Tell the nurse if it worries you; there are things they can do.
How long it takes. No one can tell you exactly. Some people die within minutes, many within hours, some over a few days. A few go on to live for longer than expected, and may move to a hospice or a quieter room. Ask the team what they expect in this case, and what happens if it takes longer.
You can stay, or not. Some families want to hold a hand at the end. Some cannot bear to be in the room and say goodbye beforehand. Both are acts of love. You can also step out and come back.
Organ Donation
If organ or tissue donation might be possible, the hospital is required to notify the local organ procurement organization, and a specialist may speak to the family. That conversation is supposed to be kept separate from the decision about life support. You decide about treatment first, and about donation on its own terms. Organ donation and the family explains how donation after life support is stopped works, and how it differs from brain death.
If This Is Brain Death
Brain death is different. If doctors have declared brain death, the person has already died, legally and medically, even though a ventilator is still moving air and the heart is still beating. There is no decision about stopping treatment to make; the ventilator is removed after the family has had time, or after organ recovery. Ask the team directly which situation you are in. Families sometimes hear "brain injury" and think "brain death," or the other way round.
When the Family Disagrees
It is common for one sibling to be ready and another not, or for a relative who lives far away to arrive and demand everything be done.
- Go back to the person. Not "what do you want," but "what would Mom have said?"
- Get everyone in the same meeting with the doctor, so nobody is relying on someone else's summary.
- Ask for palliative care or a chaplain to help. They lead these conversations every week.
- A time-limited trial can give a doubting relative time to see for themselves.
If one person has the legal authority, they decide. That does not make the disagreement go away, and it can shape a family for years. Taking a few more days to bring people along is sometimes worth it, if the team agrees it will not cause the person suffering.
Afterward
Many people who made this decision for someone they love carry a question afterward: did I do the right thing? Did I give up too soon, or wait too long?
If you made the choice from what you knew of them and what the doctors told you, you did what was asked of you. Doctors and nurses see this every week; the families who agonized are the ones who loved most. If guilt keeps returning, guilt after a death is about that. If what you feel is relief, after a long ICU stay, that is normal too; relief after a death is about that.
Ask the hospital whether they offer bereavement follow-up. Many ICUs and hospice teams call families in the weeks after.
Quick Answers
Who decides to stop life support? The person named in a health care power of attorney, if there is one. Otherwise, the relative state law puts first, usually a spouse, then adult children.
Is stopping life support the same as killing someone? No. In US medical ethics, stopping a treatment that is not helping is no different from not starting it. The illness or injury is what causes death.
How long does it take after life support is removed? It varies. Minutes to hours is common, sometimes days, and a few people live longer than expected.
Will they be in pain? The team gives medicines to prevent pain and breathlessness. Tell the nurse if anything looks uncomfortable.
Can the family be in the room? Usually yes. You can also say goodbye beforehand and step out.
In the days after, families often want somewhere to put what they remember. GetMemorial gives you a quiet place to gather photos, stories and messages from everyone who loved them, private or shared, as you choose. Start an online memorial whenever you are ready.
