There are two common misconceptions about DNR. I will address both.
- "DNR means 'do not treat'; they'll just leave him in bed to rot."
NOT true AT ALL. Example: I used to work in a hospice. ALL of our patients were DNR. We worked VERY hard to keep them comfortable. Active medical conditions can still be treated. Pain and distressing symptoms (e.g. shortness of breath) can be treated. ALL DNR means is that if a patient's heart stopped, they would not get CPR. That's it.
- "CPR would be successful. They're just writing Dad off."
CPR is successful in older people (65 years +) less than 1% of the time. In the vast majority of cases, death doesn't occur suddenly. The heart stopping is the last step in a sequence of events during which the body progressively shuts down. By the time the heart stops, there is literally no one left to save - the rest of the body is already gone.
In my area, we don't have a blanket DNR. Rather, we have something called "goals of care". Patients can choose from 3 levels of resuscitative care (full CPR, artificial respiration only, or medications and ICU treatment only), 2 levels of medical care (treat active medical conditions, may do surgery, but no CPR and no ICU admission), or 2 levels of comfort care (treat symptoms only).
When you consider that CPR is treatment, it doesn't have to be offered to patients who are unlikely to benefit from it. A doctor wouldn't put you on an antibiotic if you didn't have an infection, right? If it's unlikely your father would benefit from CPR, a DNR is completely appropriate.
