His body's in the process of giving out...kidney failure, heart failure, which is normally followed with lung problems, his breathing is shallow...and there's the sepsis, too...this isn't going to be a problem. He is walking that border between death and life right now, if he hasn't already crossed over.
Kidney failure seems to always be the harbinger of death. Once the organs start to go it is only a matter of time. God bless him.
