Patients on peritoneal dialysis have to keep track of their fluid intake, diuresis if any, and ultrafiltration rate of each cycle, as well as the total daily ultrafiltration rate. For each cycle it should be noted the time, amount in ml and the glucose level percentage of input fluid per cycle, and the output fluid in ml from which you can calculate the ultrafiltration rate which is the difference between the output and the input in the previous cycle.
