Fil- 3.1.0 Pressure Test Hydraulics (1); Fil- 3.2.0 -250 Achieved/Pressure Test Hydraulics (2); Fil- 3.3.0X Pressure Not Achieved Or Did Not Hold/Isolate Four-Way - Fresenius Medical Care 2008K2 Troubleshooting Manual

FIL- 3.1.0 PRESSURE TEST HYDRAULICS (1)

a) Figure right, connect the Four-Way Assembly (P/N
150034) to the dialyzer connectors.
b) Place the Four-Way at dialyzer level! ENSURE a
transducer protector IS NOT in the 'to syringe'
tubing segment!
c) If using a NEO-2 attach to the +Port (top, red port). If using
a 90XL attach to the Pressure Module's Gauge Port.
d) DO NOT allow tension in the Four-Way tubing
segments!
IMPORTANT! CLOSE THE SHUNT
e)
DOOR!
f) Call debug screen 2. To ENSURE the shunt door
is closed CVRCLS (2
g) PULL on the syringe plunger. Can you achieve approximately
negative (-)250 mmHg on the external meter?
Yes -250 mmHg achieved. Clamp the Four Ways's 'to syringe' tubing segment to keep the
pressure then see procedure number
No -250 mmHg could NOT be achieved! ENSURE the transducer protector, at the meter, is not
wet OR consider replacing it! If OKAY see procedure number
FIL- 3.2.0 -250 ACHIEVED / PRESSURE TEST HYDRAULICS (2)
Watch the meter for one (1) minute. Does pressure HOLD +/- 15 mmHg for one (1) minute?
Yes Pressure holds! Proceed to
No Pressure does NOT hold! See procedure number
FIL- 3.3.0X PRESSURE NOT ACHIEVED OR DID NOT HOLD / ISOLATE FOUR-WAY
Figure right,
a) clamp BOTH Four-Way Dialyzer
Line tubing segments.
b) Can you achieve -250 mmHg and HOLD it (+/- 15
mmHg for one minute) now?
Yes -250 achieved and HOLDS!
Dialysate Line segments and proceed to
No Either the transducer protector at the meter is wet OR a Four-Way tubing connection is leaking.
Locate and repair the problem then return to (ABOVE) procedure number
