'Whatever you think of resuscitation for someone with dementia who is peg-fed, the doctors had no right to make this decision without consulting the patient and his family.'
That is really the crux of the matter, edam, and that DS was given as a reason for DNR. In this case, consulting the patient wouldn't really be feasible because of his dementia.
Medically, the DNR was likely warranted, because of his dementia, and again, venting someone IS a resuss measure.
A friend whose husband died of cancer put it better, DNR is the difference between death and the possibility of a death which may be painful and traumatic to the patient, it is for those who will die, however, no matter what.
People who need to be put on a vent and who are already as ill as this man, well, there's a not insignificant chance they will not survive the procedure. We were made clear of this as well, when she went on the vent, as she was obviously not well when it became required.
In Scotland, at least, the team is allowed to make that decision on medical grounds and override the family, as far as I know, but they should and do, and did in our case, explain why if she threw another clot ressussing her was not an option.
When she did develop the pneumothorax, we were taken aside by the lead cons in ICU and our own cons, and made clear that the only way to control it was to turn down the vent and what it would be like if the pressure in the vent were maintained. The outcome was going to be the same, she was going to die, but death from the pneumothorax was going to be painful and traumatic for her, versus turning it off and letting her slip away.
Where the error is is in not consulting the family and giving DS as a reason not to resuss.
