I recently saw a video on Facebook which criticized people who hold on to full code, i.e. "do everything," in the ICU way past when they should have let natural death occur. I think it was more a criticism of patents’ families who try to impose their will on them and keep them alive by artificial means much longer than they wish to be. I, for one, can vouch for the fact that it is important for everyone to have an end-of-life conversation with their loved ones long before it is needed, and let them know their wishes in no uncertain terms. And this conversation is necessary even if one has an advance directive or a "do not resuscitate" order.
I wish I would have had that conversation with my mother. I should have initiated it with her, as she was not one who would have. I feel guilty now about having kept her alive with all kinds of uncomfortable, and possibly painful, measures a little longer than she probably wanted. However, everyone is different, and whatever decision they make after being presented with all the relevant facts is theirs alone and needs to be respected, and should not be criticized for being the "wrong" decision. Otherwise, the word "decision" in that case is just euphemistic. In other words, don't tell me I have a decision to make, if, in your mind, there's only one viable choice. That's not a decision. Just a pet peeve of mine.
