This question is so difficult to comment on. I want to tell an experience of mine to help you think things out.
I was caregiver to one particular lady who knew (with Hospice) that the end was very near. Up to then she still had some quality of life, but the last night she couldn't feed herself her nightly dish of ice-cream. Next day she ate all 3 meals at the table with help.
That night we laughed and fed her her ice-cream and as I pivoted her from the wheelchair into bed, she wanted to hold me for a while. We stood there and embraced and laughed and talked upbeat... like she
was hugging me goodby.
During that night she kept taking her bipap off. I kept checking on her (you can tell if the air isn't blowing with the right sounds) I repeatedly put it back on her............gently... all night. In the late morning when I came back to my shift, the caregiver told me she didn't wake up and was unconcious and passed quietly while sleeping.
Hospice was very pleased with the outcome. However no discussion was made either. Why? She had excellant care and a happy ending for all.
Now, if you ask me.... I believe she was ready to go and refused to keep the bipap on.
She needed it and didn't want it anymore. No words were shared.... no plans were
announced..... she just decided for herself. I'll never know.
