Tmp- 2.2.5 Achieve Negative Pressure; Tmp- 2.2.6 Negative (-)250 Achieved/Negative Pressure Holding Test; Tmp- 2.2.7X -250 Could Not Be Achieved Or It Did Not Hold/Isolate Four-Way - Fresenius Medical Care 2008K2 Troubleshooting Manual

TMP- 2.2.5 ACHIEVE NEGATIVE PRESSURE

a) Figure right, connect the Four-Way Assembly
(P/N 150034) to the dialyzer connectors.
b) Place the Four-Way at dialyzer level!
c) ENSURE a transducer protector IS NOT in
the 'to syringe' tubing segment!
d) If using a NEO-2 attach to the + (top, red) port. If
using a 90XL attach to the module's Gauge Port!
e) DO NOT allow tension in the Four-Way tubing
segments!
IMPORTANT! CLOSE THE SHUNT
f)
DOOR!
g) Call debug screen 2. To ENSURE the shunt door is indicated
closed CVRCLS = 1!
h) PULL on the syringe plunger. Can you achieve negative (-) 250 +/- 5 mmHg on the meter?
Yes -250 achieved! Clamp the 'to syringe' tubing segment to keep the pressure then see
procedure number
No CANNOT achieve -250 on the meter! ENSURE the transducer protector, at the meter, is not
wet OR consider replacing it! If OKAY, see procedure number
TMP- 2.2.6 NEGATIVE (–)250 ACHIEVED / NEGATIVE PRESSURE HOLDING TEST
Does -250 HOLD, +/- 15 mmHg, for one (1) minute?
Yes -250 HOLDS! Proceed to
No -250 does NOT hold! See procedure number
TMP- 2.2.7X -250 COULD NOT BE ACHIEVED OR IT DID NOT HOLD / ISOLATE FOUR-WAY
Figure right
a) , clamp BOTH Four-Way
dialyzer Line tubing segments.
b) Can you achieve negative (-)250 mmHg AND
does it HOLD (+/- 15 mmHg) for one (1) minute
now?
