What are the final stages (visual symptoms) of somebody dying from copd-emphysema

answered:

Shortness of breath

Heart
In general, people who are very end stage COPD will have alot of difficulty breathing and typically will have fast and shallow breathing. Eventually they cannot keep up and start retaining CO2 which makes them mentally altered and hypoxic which also makes them sluggish/loopy (and usually causes a grayish cast to the features). These changes are shortly followed by cardiac arrythmias and death.

Final stages...

Copd
In the final stages of COPD, the patient cannot ventilate themselves at all and they cannot get enough oxygen into their body. They have severe shortness of breath and often get agitated because of this. They tend to have cyanosis, or a blue color to fingers, toes, lips,etc. There are medicines that can be used to make the patient as comfortable as possible but it is not a comfortable death.
