My gran passed away last night, she was 92, not mobile and had been in a nursing home for the past two years. She has had a urine infection and been confused these past few days and tbh I feel this is a release for her. However, I am less than happy that her final moments were spent being pummelled on the chest by nursing home staff and paramedics.
Please please don't think for one moment I am upset with the people involved, I am not, they do a selfless and wonderful job. However, it seems that protocol now deems you cannot "just die" but efforts must be made to revive you. I am certain that those present were just doing their job but I so wish my Nan had been allowed to slip off without the heroics.
It IS a sudden death because despite the urine infection she had no other issues beyond the normal ones for her since her stroke. The Coroner has had to be informed etc and she had not seen a doctor for some time. I assumed she was on antibiotics but apparently not.
My Nan has wanted to die for a long time, she would not have wanted all the heart pummelling and I am relieved for her that it wasn't successful but so so wish she had just been put back into bed and had her hand held while they contacted the family. As a nurse years ago I don't recall us doing much else (circumstances depending), even for a sudden death when the patient had such underlying health issues as my Nan did. 
I am probably being unreasonable but just wanted a more peaceful death for her.
