What is not Euthanasia?
To withdraw or withhold treatment.
Not For Resuscitation (NFR) or Do Not Resuscitate (DNR).
To give necessary medications to control patients' symptoms, knowing the side effects may kill them.

How can we help? Use morphine, or Deep Palliative Sedation, which is effective, legal and ethical, is the last resort that can be used for these intractable symptoms.
