About how often is kidney dialysis done, when an elderly and somewhat fraile 
patient is taking in limited fluids and eating very little?
 
She sleeps much of the day, occasionally seems disoriented, and it seems 
clear there is limited urinary output.
 
I'm not a doctor; however, in cases where dialysis is necessary, about how 
often is the procedure done in moderate to severe cases, where there is 
almost no urine produced?
