Okay. I'm not a doctor, but if I recall correctly from my time in hospice - the "death rattle" (more genteely described as "terminal congestion") is NOT the "lungs filling up with fluid."

The person who is dying has lost the ability to clear his/her throat and the phlegm is just rattling in the back of his/her windpipe.
