I'm new to the site and these forums- and I only answered this one because it is the most recent post (as the others are all from years ago). So, I don't have any info on oxygen, but I recently moved across the country to become a caretaker for my grandmother who had a stroke.
I understand the concern of wondering if you are going to wake up to a loved one's death, as I do the same. And- to be honest- I've worked in senior health care (one of the reasons I moved back to live with my grandmother) and daily death is part of the deal when dealing with the elderly, so it's something you just have to compartmentalize and get over the emotional attachment of being a family member and be "professional" when dealing with your "patient" and then be a "family member" when dealing with your "loved one".
What I was looking for was more skills for care taking, not really the hand-holding, emotional support side of it.
If anyone is interested in starting that type of discussion, I would love to be involved. And I apologize if I offended anyone with my opinion, but being a caretaker is just one of those jobs when you have to break down and cry, you do it while taking a shower. Otherwise, it's gotta be business as usual or else you are not benefiting your patient.
Best of luck to you all!
