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!
e)
IMPORTANT! CLOSE THE SHUNT
DOOR!
f) Call debug screen 2. To ENSURE the shunt door
is closed CVRCLS (2 nd column from left) = 1!
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
FIL- 3.2.0 (page 426).
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- 3.3.0X
(page 426).
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
page 427,
procedure number FIL- 3.5.0 .
No Pressure does NOT hold! See procedure number FIL- 3.3.0X (page 426).
FIL- 3.3.0X PRESSURE NOT ACHIEVED OR DID NOT HOLD / ISOLATE FOUR-WAY
a)
Figure right,
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!
IMPORTANT!
Remove BOTH clamps from both Four-Way
Dialysate Line segments and proceed to
page 466
, procedure number TMP- 4.0.0
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
FIL- 3.0.0 (

425
).
