death rattle
Medical term for the gurgling sound sometimes heard in a dying person's breathing.
The death rattle is one of the physical signs that death is near.
Compound of 死前 (しぜん, 'just before death') and 喘鳴 (ぜんめい, 'stridor, wheezing'). The exact historical derivation is uncertain; the spelling is conventionally associated with the medical meaning.
