question: my dad is in the hospital in was in icu for 2 weeks because of heart rate racing out of control going up, down he does suffer from chf and renal failure.  While in icu we were told that he got a blood infection and started getting treated wiith antibodics immedicately. Since then he was totally disoriented, breathing rapidly, could not stay woke for long periods of time, it was scary.  Doctor's told us that there was not much more they could do for my dad.  He also had blood in his urnine from the time he's been in icu.  He is out of icu, sent on the cardaic floor, now on the kidney floor.  On th kidney floor he was seeing things that were not there and talking about things from the past and things that did not make since.  There is still blood in the urnine, told that is from uti, still do not know if blood infection is cleared up.  Can a uti cause a blood infection (sepsis)  Please we need answers?
