I watched this in action with my father's death. My mother had a long nursing career and had a talk with the doctor that lasted about 15 minutes (it was 20 years ago), after that a large morphine dose was added to his IV. Within 5 minutes I watched my dad stop breathing. My Dad was in his early sixties, morbidly obese, this condition was aggrevated by his lifelong fear of doctors. Dad needed hip replacements but wouldn't consider it because of his medical phobia. This caused his lack of mobility which caused urinary track infections from his dificulty moving to a toilet chair. He was in the hospital for chronic UTI's when my mom made the decision. He was lucent and not at all ready to die. Mom has passed too and it feels cathartic to say this.
