Another natural escape used to be pneumonia, or cardiac arrest. Unless DNR is in place before the disease takes hold, then choice is taken away, especially if spouse/next of kin insists the person has to be force fed, one way or another and given antibiotics.
DNR is solely an instruction to not attempt to resuscitate, i.e. after the heart has stopped. It does not have any influence on treatment prior to death. The patient would need to write a witnessed Advanced Decision (Living Will) making their choices plain. Alternatively, a Lasting Power of Attorney would give a relative or other trusted nominee the right to make health decisions. Sorry if that sounds a bit know-all, it’s not meant to. I went through all this with my Mum so have experience.
