Those who are dying may lose their ability to swallow, resulting in such an accumulation. While it is medically established that the death rattle is a strong indication that someone is near death, it can also be produced by other problems that cause interference with the swallowing reflex, for instance, brain injuries.
It is sometimes misinterpreted as the sound of the person choking to death. In terminal care, drugs such as hyoscine hydrobromide or atropine may be used to reduce secretions and minimise this effect.
Death rattle may also be used to refer to machines. A machine (usually an engine) with death rattle typically suffers from a spun bearing or other major mechanical failure, causing it to make strange noises.
Widespread understanding of the significance of the death rattle has led to its common use in literature.
- In common parlance we call it a "death rattle." It is one of those terms that through use has passed into the realm of fantasy so that many no longer believe it is an actual biological phenomenon. In fact, it is. Forensics experts tell us that the death rattle is the result of involuntary spasms in the vocal box brought on by the increased acidity in the blood following death. The noise itself is alternately described as a loud bark or whooping rasp emitted by a victim sometime after death.

- He was getting up his last "effect"; but he never finished it.
- "Next morning, around six o'clock, the servant entered the room with a candle. He found his master lying on the floor, the pistol beside him, and blood everywhere. He called, he touched him; no answer came, only a rattling in the throat."
- "Life, like a child, laughs, shaking its rattle of death as it runs."
- "I think I may have dropped off into a light sleep, but my senses were still wide awake, and i suddenly startled into intense consciousness by a hurried, angry sound, the most awe-inspiring sound anyone can hear, the Death Rattle."
- "...but the baby's crying, and its death rattle were heard, and they were discovered."
