I signed the DNR, with the consent and agreement of my family. When I signed it, we went over it in great detail so that it was understood exactly what this meant. All normative means of sustaining life, such as food and water, antibiotics, and other such care such as maintaining the ventilator she is on will be continued. If my wife has a "code", they will adminster drugs to try to restart the heart, but will not take "heroic" measures such as CPR, shocking the heart, or other extreme measures.
The DNR was very clear about this and I am assured that normal care will be take to maintain her life and the best comfort she can have at this time.
Your prayers for her soul are appreciated. She has not been in any form of church for over 20 years. May the Lord meet with her and have mercy upon her in this condition.
