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 in the dialyzer holderl!
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 or kinks in the Four-Way
tubing segments!
e)
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 between
-245 and -255 mmHg on the external meter?
Yes -250 mmHg achieved. Clamp the Four Ways’s ‘to syringe’ tubing segment to hold the
pressure then see procedure number FIL- 3.2.0 (page 469).
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 469).
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 470, procedure number FIL- 3.5.0.
No Pressure DOES NOT hold! See procedure number FIL- 3.3.0X (page 469).
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 509, 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 (
page
468).
