When my dad died, he spent the last week or so in the hospital at the palliative care unit (where the primary concern is to ease suffering and not extend life, for those fatally ill). When I arrived I was given a small booklet called something like "At the end of life" which in a very matter-of-fact went through how life ends. It described how the body works, what gives in first and last, what often happens at the moment of death (eg agonal breathing). It based this on medical facts and experience, not religion or beliefs. I found it to be a great support during those days. Leaving out beliefs and religion and focusing on the medical/biological, and to-the-point made it easier to accept. There is likely something like this booklet in every language for those that search for it.
