The short answer
The last days of life follow a recognisable pattern. Knowing what breathing changes, noisy secretions, reduced intake and withdrawal mean helps families interpret what they are seeing.
Breathing in the last days becomes irregular, with pauses and cycles of deep and shallow breaths; this is expected and is not usually a sign of suffering.
Noisy breathing from pooled secretions occurs in roughly half to two-thirds of dying people and distresses families more than patients; drying medications have not outperformed placebo in trials.
People stop eating and drinking because they are dying; stopping eating is not what causes the death, and forced food or fluids can cause choking and discomfort.
Artificial nutrition has no known benefit in the last days of life and may increase the risk of aspiration and infection.

The full explanation.
Dying has a shape you can recognise
In advanced cancer, the last days usually follow a pattern. Knowing the pattern does not make it easier to watch. It does tell you which changes are expected, which are worth a phone call, and which have a treatment.
Breathing changes
Breathing becomes irregular. It may be shallow, then deep and rapid, then stop for ten or twenty seconds before starting again. That cycling pattern is called Cheyne-Stokes respiration, and in a large study of dying cancer patients it appeared almost entirely within the last three days of life. You may also see the jaw drop open and move with each breath. In an unconscious person these are reflexes rather than signs of suffering. Tell the nurse if the person frowns, tenses, or looks like they are working to breathe, because breathlessness can be treated with low-dose opioids and a fan.
The noisy breathing
Saliva and airway fluid pool in the throat when someone is too weak to swallow or cough. The resulting sound, often called a rattle, occurs in roughly half to two-thirds of people in the last days, typically beginning a day or so before death. It is loud, and it is hard to sit beside. The evidence is that it distresses the people in the room far more than the person in the bed, who is usually deeply unconscious by then. Randomised trials of glycopyrrolate, hyoscine, atropine and octreotide have not shown a clear advantage over placebo. Turning the person onto their side, raising the head of the bed, and stopping or reducing intravenous fluids tend to help more. Suctioning usually makes secretions worse.
Eating and drinking stop
This is the change families agonise over most. Appetite and thirst fall away, then disappear. The illness causes the person to stop eating; stopping eating is not what causes the death. In the last days the body can no longer use nutrition, and artificial feeding has no known benefit at this stage while raising the risk of aspiration and infection. Intravenous fluid above roughly 500 mL a day in the final week is associated with more secretions and swelling. Offer sips and tastes if the person wants them, and stop when they turn away. Mouth swabs, ice chips and lip balm treat the dryness that fluids would not.
Sleep, withdrawal and confusion
Most people spend more and more time asleep, answer slowly or not at all, and lose interest in what is happening around them. Confusion in the last days is common, reported in 50 to 90 percent of people before death. It can be quiet and withdrawn, or restless, agitated and frightening to watch, sometimes with hallucinations or picking at bedclothes. Some causes are reversible: an unrelieved bladder, constipation, dehydration, or a medication. Report new agitation rather than assuming it is simply the end.
Circulation and urine
Hands and feet turn cool and become blotchy or blue. Urine output drops sharply and darkens, often to less than a cup a day. A pulse at the wrist may become impossible to find. These are late signs, generally within the last days or hours.
Brief clarity
Some people become suddenly alert, recognise relatives, speak clearly, or ask for something to eat, after days of little response. Clinicians and families have described this for a long time. It is usually short and it does not mean the illness has turned around.
Presence
Most people can still hear after they can no longer speak or open their eyes. Say who you are when you come in. Say what you are doing before you move them. Ordinary conversation in the room is fine. Touch, music, and a quiet, unhurried voice are the things most families report being able to offer, and they are enough.

Common questions
Is the rattling sound in my mother's throat choking her?
No. The sound comes from saliva and secretions pooling in the throat of someone too weak to clear it. By the time it appears, most people are deeply unconscious and do not appear to experience it as distress. Turning her onto her side, raising the head of the bed and reducing intravenous fluids help more than suctioning, which usually increases secretions.
Are we starving him by not giving food or a drip?
No. Loss of appetite and thirst is part of the dying process, not the cause of it. In the last days the body cannot use nutrition, and intravenous fluid above about 500 mL a day is linked to more noisy secretions and swelling. Mouth care with swabs, lip balm and small sips if the person wants them addresses the discomfort that fluids would not.
He suddenly woke up, talked clearly and asked for food. Is he getting better?
A brief return of alertness close to death has been described repeatedly by clinicians and families, sometimes called terminal lucidity. It is usually short, and it does not mean the illness has reversed. Use it if you want to, without treating it as evidence that the prognosis has changed.
How will we know death has happened, and who do we call?
Breathing stops, there is no pulse, the eyes may stay open, and the muscles relax. If the person is on hospice, call the hospice number, not 911, at any hour; a nurse will come, confirm the death and contact the funeral home. Calling 911 can trigger resuscitation attempts unless a valid do-not-resuscitate or POLST form is at hand.
Should we tell him it is all right to go?
Some families find that useful and some do not. There is no evidence that permission changes the timing of death. People also commonly die in the few minutes a relative steps out of the room, which does not mean anyone failed to be present.
