Online Pht Failure; Changing The Bibag Disposable During Treatment - Fresenius Medical Care 2008T Operator's Manual

Online PHT Failure

If the machine fails the online PHT, the message " ONLINE PHT FAILED " is displayed in the
Status Box. The blood pump does not stop during this alarm condition. This alarm can be
cleared by pressing the RESET button.
Online PHT failures can be caused by problems that make it difficult to control the patient's
fluid balance. Some failure alarms can be caused by air entering the hydraulic system from
faulty concentrate or dialyzer line connections. The operator should inspect the machine for
external air intake and fluid leaks, and make the appropriate corrections if possible.
Discontinue the treatment and take the machine out of service if an online PHT failure alarm
recurs. The hydraulics should be inspected by a qualified technician before returning the
machine to service.
If an online PHT failure occurs once during a treatment, perform the Pressure Holding Test
(from the "Test & Options" screen) before the next treatment to verify the integrity of the
hydraulic system.

Changing the bibag disposable during treatment

Note: When changing the bibag disposable during treatment, the automated empty feature
cannot be used so the bag will need to be emptied manually.
Note: If a bag is changed during treatment, a pause of 6-10 minutes should be expected as
the new bag fills. The dialysis machine will automatically go into bypass mode until the new
bag is on-line and conductivity comes into the acceptable range.
If the bibag disposable needs to be changed during the treatment, use the following steps:
1. Lift up on the dark-gray bibag door handle to open the bibag door.
2. Wait 30 seconds to relieve the pressure in the bag.
3. Lift up the bibag disposable by the handle, remove the used bag and dispose of it per unit
protocol. Since the used bag is not empty of fluid, be careful to prevent spills.
Note: If disposing of leftover bicarbonate solution down a drain, be sure to run plenty of hot
water down the drain too. This will help prevent bicarbonate buildup in the plumbing.
4. For the new bibag disposable, remove the white plastic seal from underneath the water
and bicarbonate nozzles. Hang the bag on the machine's bibag connector nozzles.
5. Close the bibag door, making sure it latches firmly in place. An audible click indicates
the door is closed. The treatment will resume after the machine fills the bag with heated
water.
