Is not acceptable
It is assisted dying. Today’s medical technology can keep a dying human being alive for many years beyond what would have been possible even a generation ago. But death should take its course without your (or anyone else’s) intervention.
Typically, if you would want to die naturally (without being supported by a machine), it is important to make your wishes known that you would prefer not to be kept resuscitated.
Normally, you have the right to refuse treatment against your wishes if you are dying, and your physician will respect your decision and can prescribe medication for pain.
