An honest description of what dying looks and sounds like: breathing changes, the death rattle, mottling, terminal restlessness, and what is normal at the end.
Most people have never been in the room when someone dies, so the physical reality is frightening simply because it is unfamiliar. This piece describes plainly what families commonly witness: changes in breathing including long pauses and Cheyne-Stokes patterns, the wet sound often called the death rattle, cooling and mottled skin, decreased appetite and thirst, restlessness or reaching, and periods of unresponsiveness.
It explains which of these are normal parts of dying rather than signs of suffering, what comfort measures help, and when to call the care team.
