Near the end of life, breathing often becomes irregular: shallow, then deeper, with pauses that can last many seconds. A wet, rattling sound, often called the death rattle, comes from saliva the person can no longer swallow. It is hard to hear, but it does not seem to be painful for the dying person.
Of all the changes at the end of life, breathing is often the one families notice first and remember longest. You find yourself counting the seconds between breaths, leaning in to check, jumping at every gurgle. It is exhausting, and it is natural to wonder whether your loved one is struggling. This guide explains the common breathing changes in the last days and hours, what they usually mean, what helps, what does not, and when to call the hospice nurse.
Why breathing changes as the body slows down
Breathing is controlled by the brain in response to signals from the blood. As the heart, kidneys and other organs slow, those signals change, the muscles weaken, and the person spends more time deeply asleep. The National Cancer Institute describes breathing in the last days that may become irregular, with very shallow breathing, short periods of not breathing, or deep, rapid breathing. Cleveland Clinic notes that as death nears, a person may go longer periods without breathing. These patterns are part of the body shutting down, and they do not by themselves mean the person is in distress.
The most common breathing changes
Irregular breathing
Breaths may come fast for a minute and then slow, or be shallow and then suddenly deep. The rhythm no longer looks like normal sleep.
Pauses (apnea)
Breathing may stop for a few seconds, sometimes much longer, and then start again, often with a deeper breath or a sigh. The pauses may get longer over hours. Many families think each pause is the last one. It helps to know this can go on for a long time.
Cheyne-Stokes breathing
This is a specific cycle: breaths get gradually deeper and faster, then gradually shallower and slower, then there is a pause, and the cycle starts again. It is named for two doctors who described it, and the National Cancer Institute lists it among the signs seen as death approaches. It can look alarming, but it is a pattern of the brain’s breathing control, not a sign of choking.
Mouth breathing and jaw movement
The mouth often falls open. In the final hours, breaths may become small movements of the jaw or chin, with long gaps. These last breaths are usually a sign that death is very close.
Noisy, wet breathing: the “death rattle”
When a person is too weak to swallow or cough, saliva and mucus collect at the back of the throat. Air moving over it makes a gurgling or rattling sound. The National Cancer Institute says the rattle can be very upsetting for those at the bedside but does not seem to be painful for the person, and its guidance for clinicians notes that rattle does not appear to be distressing for the patient, even though families may understandably read it as struggling for breath. It is usually a sign that death may be hours to days away, though timing varies.
Breathlessness in someone who is still awake
This is different. A person who is awake, anxious, working hard to breathe, or saying they cannot get air needs help now, and there is a great deal the team can do. Call the nurse.
A rough timeline
| When | What you may notice | What helps |
|---|---|---|
| Weeks | Shortness of breath with activity, more time resting, waking less | Sitting up, a cool fan, pacing activity, medicines the nurse prescribes for breathlessness |
| Days | Irregular breathing during sleep, pauses, some noisy breathing | Repositioning, mouth care, a calm room, calling the nurse with changes |
| Hours | Longer pauses, Cheyne-Stokes cycles, rattle, jaw breathing, fewer and gentler breaths | Turning onto the side, mouth care, presence, touch, speaking softly |
This is a general guide, not a schedule. Some people move through these stages over a week; others in a single afternoon; some skip steps entirely. Our guide to signs death is near puts breathing in context with the other changes.
What families can do
- Change position. Raising the head of the bed a little, or turning the person onto their side with pillows behind the back, often lets secretions drain and quiets the rattle. The National Cancer Institute notes that repositioning is often helpful. Ask the nurse or aide to show you how to turn safely.
- Mouth care. Breathing through the mouth dries the lips and tongue. Moisten them with a damp swab, and apply a lip balm the nurse recommends. Do not give sips of water to someone who can no longer swallow; it may pool in the throat.
- Cool air. MedlinePlus suggests a breeze from an open window or a fan for people who feel short of breath. A small fan aimed gently across the face can ease the feeling of air hunger.
- Keep the room calm. Loose clothing and light bedding. Fewer people at once. Soft music if they liked it.
- Stay close, and talk. Many experts believe hearing may continue late, and families often find comfort in speaking to the person, holding a hand, and saying what they want to say.
- Look after the listeners. If the sound of the rattle is too much, step out for a few minutes. It is fine. Someone else can sit.
When medicines help
Medicines have a clear role for breathlessness and a more limited one for the rattle.
- For breathlessness and air hunger, a small amount of an opioid such as morphine can ease the sensation and slow rapid, anxious breathing. Used this way, it has not been shown to shorten life. Read morphine in hospice: myths and facts.
- For anxiety that makes breathlessness worse, the doctor may prescribe a calming medicine.
- For the rattle, the doctor may prescribe a medicine that dries secretions. The evidence that these work is mixed, and they do not help everyone, so positioning and mouth care stay important.
- For a specific cause, such as fluid on the lungs in heart failure, the team may adjust other medicines.
Several of these may be in the comfort kit, with written instructions. Give them only as the nurse told you, and call if you are unsure.
What about oxygen and suctioning?
Oxygen can help when breathlessness is caused by a low oxygen level, and many people with COPD or lung disease use it for months on hospice. But it is not automatically helpful at the very end. The National Cancer Institute’s guidance for clinicians says routine oxygen for patients without a documented low oxygen level is not supported by the evidence. In the last hours, a nasal cannula or mask can dry the nose and mouth or bother the person. It is fine to keep it on if it seems to comfort them, or to take it off; ask the nurse.
Suctioning. The nurse may use gentle suction of the mouth in some situations. It does not stop the body from producing secretions, and families are not expected to do deep suctioning at home.
What these changes usually are not
Irregular breathing, pauses and the rattle, in someone who is deeply asleep and whose face and body look relaxed, usually are not signs of choking or suffering. Signs that someone may be uncomfortable include a furrowed brow, grimacing, restlessness, moaning with each breath, or using the neck and shoulder muscles hard to breathe. If you see those, call. If you are not sure, call. For more on agitation, see terminal restlessness.
When to call the hospice nurse
If the person is on hospice, call the hospice line, not 911, when:
- They seem to be struggling to breathe, look frightened, or say they cannot get air.
- Breathlessness is not eased within the time the nurse told you to expect after a comfort medicine.
- The rattle starts, or gets louder, and you want help with positioning or medicine.
- Breathing changes suddenly, or you think death may be close and you want a nurse there.
- Breathing has stopped and you believe they have died. Take your time; there is no emergency. See what to do when someone dies at home in Michigan.
At Lily, a real person answers 24 hours a day, and a nurse can come to the house. What happens when you call hospice at night. If your loved one is not on hospice and has new or severe trouble breathing, call their doctor or 911 as you normally would. If they are seriously ill and breathlessness is becoming part of daily life, call Lily to talk it through, or read Is it time? A family’s gentle guide.
Common questions
Is the death rattle painful?
It does not seem to be. According to the National Cancer Institute, the rattle can be very upsetting for those at the bedside but does not appear to be painful or distressing for the person, who is usually deeply unconscious.
How long does the death rattle last before death?
It is often a sign that death may be hours to days away, but no one can predict it exactly for a particular person.
What is Cheyne-Stokes breathing?
A repeating cycle of breaths that grow deeper and faster, then shallower and slower, followed by a pause. It is common in the last days of life and reflects changes in the brain’s control of breathing.
How long can pauses in breathing last?
Pauses can last a few seconds or much longer, and they often lengthen over the final hours. Breathing may start again after what feels like a very long gap.
Should we give oxygen at the end of life?
Oxygen helps when a low oxygen level is causing breathlessness. At the very end it is not automatically helpful and can dry the nose and mouth. Ask the nurse whether it is still helping your loved one.
Should I give water if their mouth sounds dry or wet?
Not if they can no longer swallow. Moisten the mouth and lips with a damp swab instead, and turn them on their side if secretions are pooling.
Can they hear us when breathing changes like this?
Many experts believe hearing may continue late in dying. Talking softly, holding a hand and saying what you want to say can comfort both of you.
Does morphine for breathing speed up death?
Studies of opioid use in hospice and palliative care have not found that appropriately adjusted doses shorten life. Morphine is used to ease the feeling of breathlessness.
Hospice isn’t giving up. It’s showing up. If you are in Oakland, Macomb or Wayne County, call (248) 955-5100. A real person answers, 24 hours a day.
