It seems like DNR's put a huge burden on caregivers, EMT, police. fire department, 911 etc.
Their mission is to render aid and save lives.

I feel sad about that happening to your mother. My hope is that the fireman receives better training.

I was told by my Mother’s nurse that if 911 is called you are giving permission to resuscitate, so the EMT was doing his job. Her advice for my Mother was to wait an hour before calling anyone if she stopped breathing.

I had a DNR and when I had lung surgery they resuscitated me and put me on a ventilator. Later on I told the doctor that I told her I didn't want to be resuscitated or put on a ventilator. He told my sister who was my executor that he Considered a murder to not save my life. Now I'm not sure what to say but they don't always follow your wishes. I was not happy at the time but now I'm I'm OK but it's sometimes I still go through so many exacerbations and that I wish they had just let me go.
