TMP- 1.0.17 CHECK FILLING PROGRAM (FILACT)
Call debug screen 1. Watch FILACT for one minute. Proceed accordingly:
FILACT = 1 (constant or intermittent): Proceed to page 168,
PROBLEMS.
FILACT = 0 (constant): See procedure number
TMP- 1.3.0 CHECK VENOUS PRESSURE STABILITY
a) Assure the P port (at the Level Detector module) is EMPTY.
ven
b) From debug screen 1, if (and ONLY if) VEN does NOT = 0 +/- 5 calibrate VENOUS
PRESSURE per procedure.
c) Referring to the Figure (right), attach a piece of
tubing, with a syringe attached, to the P
d) Push on the syringe plunger until VEN is approximately
+300 mmHg then clamp the syringe.
e) A decrease of greater than 3 mmHg in 30 seconds may
indicate a leak inside the Level Detector module.
IMPORTANT!
f) Do NOT detach the tubing so that
VEN remains about 300 mmHg for subsequent
procedures.
g) See procedure number
TMP- 1.4.0 PRESSURE TEST
IMPORTANT!
a) Turn Dialysate flow is OFF (Dialysate Flow on/off LED
blinks).
b) Referring to the Figure (below, right), attach the four way test assembly
to the dialyzer connectors. Hang the assembly over the dialyzer holder.
c) If using a NEO-2 meter, attach to the TOP pressure port (see Figure
right)!
IMPORTANT!
d) Close the shunt door!
e) ASSURE all assembly connections are TIGHT!
f) Pull on the syringe plunger. Are you able to
create approximately -250 mmHg AND
HOLD it (+/- 20 mmHg per minute) on the
external meter?
Yes See procedure number
1.4.2 (page 183).
No Negative pressure leak! Remove the tubing from the P
port then see procedure number
