Not a nurse, but a health care
Did 8+ plus years in children's Hospice and work in a nursing home now
Always open the window and have been directly taught to
Now I'm an atheist, didn't marry in church, kids not christened etc
Still, whenever giving last offices or after death care (we had special room, so young people could rest with us instead of funeral directors) I still talk to the patient as well
A few reasons for this: it's sort of natural, particularly when you're used to describing what you're doing to non-verbal patients, vulnerable people etc
If family, particularly parents, happen to be in the room, you're narrating for them too, so they know what to expect
You're teaching inexperienced staff on the job, as you go, what next steps are
And it just feels more respectful. They may be deceased, but they were still a person
I'll try not to be crass with the language I use, but if you're like me and think that when you're dead, you're gone and know nothing about it, what difference does it make anyway?
I've looked after families from many different religions and cultures, and will do anything I can to respect people's beliefs. Doing that doesn't negate mine
Unfortunately, end stages of life can produce unpleasant smells, so opening a window doesn't hurt
Yes, it's superstition, but most health cares do it because it's part of the process, same as still talking to the patient etc
Plus, I've been surprised by how many strong non-believers, like myself, have had a wobble right near the end and taken faith, prayed, had their babies christened
Not my place to judge, and it's not like we'd hop up and go, oh we opened the window for their soul: the window would just be open
In their grief, it's unlikely they'd even notice, let alone question why
