Autotest- 3.1.0 Create Negative Pressure; Autotest- 3.2.0 B; Autotest- 3.2.0 Between -248 And -250 On The Meter/Negative Pressure Holding Tests; Autotest- 4.0.0X Pressure Cannot Be Achieved Or It Did Not Hold/Isolate Four Way - Fresenius Medical Care 2008K2 Troubleshooting Manual

AUTOTEST- 3.1.0 CREATE NEGATIVE PRESSURE

a) The screen says "6. Pressurize until dialysate pressure reads -250 mmHg...".
b) PULL on the syringe plunger. Can you achieve between -248 and -252 mmHg on the external meter?
Yes Between -248 and -252 on the meter. See procedure number
No Between -248 and -252 CANNOT be achieved! ENSURE the Transducer Protector, at the meter
is not wet OR consider replacing it. If OKAY, see procedure number
(page 530).
AUTOTEST- 3.2.0 BETWEEN -248 AND -250 ON THE METER/ NEGATIVE PRESSURE HOLDING TEST
a) CLAMP the 'to meter' tubing segment.
b) Does the meter pressure HOLD, +/- 15 mmHg, for one (1) minute?
Yes Pressure HOLDS! Proceed to
No Pressure does DOES NOT hold! See procedure number
AUTOTEST- 4.0.0X PRESSURE CANNOT 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 between -248 and -252
AND does it HOLD it, +/- 15 mmHg, for one
(1) minute now. TWO (2) possible
scenarios below:
1)
IF still CANNOT achieve between -248 and -252 OR it does NOT HOLD: 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
2)
IF you CAN achieve -248 and -252 AND it HOLDS: See parts a THROUGH e below:
a) Turn the machine OFF!
IMPORTANT!
b)
c) Turn the machine on and return to Dialysis Program ("Select Program" → 'Dialysis' →
'CONFIRM').
IMPORTANT!
d)
e) Proceed to
page 531
Remove BOTH clamps from the Four -Way dialyzer line segments.
Turn Dialysate Flow OFF (Flow on/off lamp blinks)!
