Is the excess fluid loss/gain limit related to the patient fluid removal set flow rate?

Hi Manny,
The 'excess patient fluid loss/gain limit' alarm is NOT related to the 'patient fluid removal (PFR) set flow rate. The Prisma Excess Patient fluid loss or gain is a user set limit that defines the maximum patient fluid variance (either a loss or gain) that is permissible within a 3 hour time window. The limit, which ranges from 130 to 400 mL is programmed during set up according to physician order or hospital protocol. The limit cannot be adjusted during therapy. This is an added layer of protection for patients. Once the limit is breached, the treatment must be terminated via 'end treatment' as opposed to changing the set. It is important to remember that the limit does not replace clinical judgment. Patient hemodynamic stability must be continuously a*sessed.
The PFR or 'patient fluid removal' is used for volume management and is the amount of fluid prescribed by the physician to be removed hourly by the Prisma pump.

Maureen,
Perhaps this is semantics, but I think that the patient excess fluid limit is related to the PFR rate. The fluid balance applied toward the excess limit is the variance from the the run-time-adjusted actual patient fluid removal volume. If I set a PFR of 100 ml/hr (1.67 ml/min) and the pump, due to alarms and bag changes, only runs for 56 out of 60 minutes, then the time-adjusted PFR would be 93 mL (56 minutes times 1.67 ml/min) . If the actual PFR is 73 ml then I would have a patient gain of 20 ml. The fluid balance is recalculated every minute over a running 3 hour window. Is this correct?
