Agonal breathing is irregular gasping that fails to move air, signaling cardiac arrest in a sudden collapse or the final stage of an expected death.
If someone collapses without warning and is only gasping, call 911 now.
For a loved one in hospice care, agonal breathing is an expected change. At this stage, your first call goes to your hospice nurse, and our San Diego team comes to you.
Key Highlights
- Agonal breathing appears in up to 40% to 60% of out-of-hospital cardiac arrests.
- An adult who is unresponsive and only gasping needs a 911 call and CPR.
- In a study of 357 people with advanced cancer, breathing with jaw movement was strongly linked to death within 3 days.
- When a hospice patient dies at home, families are advised to call the hospice line instead of 911.
- California EMTs start resuscitation unless they can confirm a valid DNR or POLST order.
Why Does Agonal Breathing Happen?
Agonal breathing happens when a reflex keeps pulling in gasps after the body can no longer breathe effectively. The American Heart Association describes the pattern as slow, irregular gasping that cannot ventilate the lungs.
The name comes from the Greek word for struggle, which is why the term frightens families. The gasps are automatic. A knee jerks when a doctor taps it, and the patient never chooses to kick. Agonal gasps work in a similar way.
Agonal breathing shows up in two very different settings. One is a sudden cardiac arrest, where fast action can save a life. The other is the last stage of a long illness, where the goal is comfort.
Families caring for an aging parent often notice agonal breathing alongside other end-of-life changes in the elderly, such as cool hands and long stretches of sleep.
Does Agonal Breathing Mean I Should Call 911?
Call 911 when someone collapses without warning and is only gasping, and call your hospice nurse first when the person is a hospice patient whose death is expected.
For bystanders: agonal gasps look like breathing, and that confusion costs time. The American Heart Association reports the pattern in up to 40% to 60% of out-of-hospital cardiac arrests and names it a common reason bystanders miss the emergency. The AHA tells the public to call 911 and start CPR whenever a person is unresponsive and only gasping. The 911 dispatcher will coach you through what to do until help arrives.
For hospice families: agonal breathing in a loved one on hospice is an expected part of dying. The Hospice Foundation of America advises families to call the hospice’s 24-hour line instead of 911 when a hospice patient dies at home.
A 911 call sends paramedics trained to resuscitate. California EMTs proceed with resuscitation unless they are certain a valid DNR order exists, so the state EMS agency recommends keeping the DNR or POLST form posted near the patient.
| Your situation | What the gasping likely means | Who to call first | What to keep in mind |
| Sudden, unexpected collapse | Cardiac arrest | 911 | The dispatcher will guide you through CPR |
| Hospice patient, DNR or POLST posted | Final stage of an expected death | Hospice nurse | Paramedics can honor a form they can see |
| Hospice patient, form missing or unsigned | Final stage of an expected death | Hospice nurse | If 911 is called, EMTs will attempt resuscitation |
| Hospice patient, and you feel unsure | Needs a nurse’s assessment | Hospice nurse | Call any time, day or night |
Do you give CPR for agonal breathing?
Yes, when the gasping comes with a sudden, unexpected collapse. The American Heart Association treats gasping as abnormal breathing, so bystanders should call 911 and begin chest compressions right away. For a hospice patient with a DNR or POLST order, CPR runs against the person’s own wishes, and the hospice nurse is the right call.
Should I call 911 if a hospice patient has agonal breathing?
In most cases, no. Your hospice nurse can come to the bedside, check your loved one’s comfort, and guide the family through the final hours. Paramedics who arrive without seeing a valid DNR form will attempt resuscitation. If you ever feel unsure what to do, call hospice first and follow the nurse’s direction.
Recommended: Keep the signed DNR or POLST form and the hospice phone number posted near the bed, where anyone in the home can find them.
Our medical social worker helps families plan advance directives and emergency wishes, so the paperwork is settled long ahead of this stage.
What Does Agonal Breathing Look and Sound Like?
Agonal breathing looks like slow, uneven gasps, sometimes with the jaw moving on each breath, and it can sound like snoring or gasping. Each breath can look like hard work, and the pace between breaths changes from one gasp to the next.
The jaw movement is where the nicknames guppy breathing and fish-out-of-water breathing come from. Hospice families hear both terms from nurses and in online searches.
| Breathing pattern | What you see and hear | When it tends to appear |
| Agonal breathing | Slow, uneven gasps; the jaw may move with each breath | Early in a cardiac arrest, or late in a terminal illness |
| Cheyne-Stokes breathing | Breaths that grow deeper, then shallower, then pause | Mostly in the last 3 days of life in advanced cancer research |
| Death rattle | A wet, gurgling sound with each breath | Mostly in the last 3 days of life in the same research |
What is guppy breathing?
Guppy breathing is a nickname for gasping in which the mouth opens and closes with each breath, much like a fish pulling at water. Clinicians track a closely related sign called respiration with mandibular movement. In research on people with advanced cancer, that sign was one of the late changes most closely linked to death within days.
What is the difference between agonal breathing and death rattle?
Agonal breathing is a gasping reflex. The death rattle is a wet, gurgling sound from saliva that collects in the throat once a person can no longer swallow. Both can happen in the same person during the final stage, and a hospice nurse reads them together with other changes in the body.
Is a Person Aware During Agonal Breathing?
A person with agonal breathing is most likely unconscious, and Cleveland Clinic explains that the gasps are only a reflex, with no agony behind them.
Gasping looks hard from the chair beside the bed. The person in the bed is most likely past the point of noticing it.
Our nurses read comfort from the face and body, the same way we assess pain at the end of life for patients who can no longer speak. Any sign of distress gets a response from the team.
Red flags that mean call your hospice nurse now:
- Your loved one seems awake and frightened.
- Your loved one grows restless or agitated, which can point to terminal agitation.
- You cannot tell whether breathing has stopped.
Our nurses are on call 24/7 and will come to the bedside when a breathing change worries you.

How Long Does Agonal Breathing Last Before Death?
Agonal breathing near death follows no reliable clock, so hospice teams treat it as a sign that the body has entered its final stage.
In a study of 357 people with advanced cancer, breathing with jaw movement was strongly linked to death within 3 days. The same research found that only 54% of patients showed any of the late physical signs in their final 12 hours.
A calm, quiet final day is common, and the absence of gasping does not mean a sign was missed.
Other changes tend to show up in the same window, including mottling of the skin and the shifts families see during the transitioning stage of hospice.
Say your dad is home on hospice and, at 2 a.m., his breathing turns to slow gasps with long gaps between them. Call the hospice nurse, sit close, and hold his hand. Counting seconds between breaths will not tell you when the last one comes, and your nurse can talk you through what you are seeing.
What Can Families Do During Agonal Breathing?
Families can stay close, call the hospice nurse, and leave comfort care to the team.
Holding a hand, talking softly, praying, or playing a favorite song are all good ways to spend these hours. You do not have to fix the breathing, and you cannot do this part wrong.
Families searching for words can lean on our guide to what to say to someone who is dying, which offers simple phrases for the bedside.
When breathing distress gets out of control at home, our team can start Continuous Care, which brings hospice staff to the bedside for several hours a day, up to 24 hours a day, until symptoms settle.
TL;DR: What to Remember About Agonal Breathing
- Agonal breathing is a gasping reflex that cannot move enough air into the lungs.
- After a sudden collapse, call 911 and follow the dispatcher’s CPR instructions.
- For a hospice patient, call the hospice nurse first and keep the DNR or POLST form posted near the bed.
- The person is most likely unconscious during agonal breathing, and the timing of death still varies.
If someone you love has a life-limiting illness, we can walk you through what the final days may look like and put a plan in place early.
Frequently Asked Questions About Agonal Breathing
Can agonal breathing happen to someone who is not dying?
Yes. Agonal breathing often appears early in a sudden cardiac arrest, when the person can still be saved. The American Heart Association urges bystanders to treat gasping as a sign of cardiac arrest, call 911, and start CPR right away, since the benefit of CPR far outweighs the risk of pressing on a chest that did not need it.
Does agonal breathing happen to everyone who is dying?
No. Many people die without any dramatic breathing change. In the advanced cancer study mentioned above, only 54% of patients showed any of the late physical signs in their last 12 hours of life. A quiet, gentle final stage is common, and a missing sign does not mean the family overlooked anything.
Is agonal breathing a sign that death is near?
In hospice care, yes. Gasping breaths, especially with the jaw moving on each breath, point to the final stage of dying. Exact timing still varies from person to person, so hospice nurses read the breathing alongside other changes, such as skin color, responsiveness, and pulse, to guide the family.
What should I do after the last breath?
Call your hospice line. A hospice nurse comes to confirm the death and helps with next steps, including contacting the funeral home. You do not need to call 911. Families can take time to sit with their loved one, hold a hand, and say goodbye while they wait for the nurse to arrive.
Can I hold my loved one during agonal breathing?
Yes. Touch and presence are welcome during agonal breathing and after death. Hold a hand, rest a palm on an arm, or sit close and talk. If you feel unsure about moving or repositioning your loved one, ask your hospice nurse to show you what keeps them comfortable.
