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 -245 and -255 mmHg on the external meter?
Yes Between -245 and -255 on the meter! See procedure number AUTOTEST- 3.2.0 (page 575).
No Between -245 and -255 CANNOT be achieved! ENSURE the Transducer Protector, at the meter
is not wet OR consider replacing it. If OKAY, see procedure number
AUTOTEST- 4.0.0X
(page 575).
AUTOTEST- 3.2.0 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
page 576, procedure number AUTOTEST- 5.0.0.
No Pressure does NOT hold! See procedure number AUTOTEST- 4.0.0X (page 575).
AUTOTEST- 4.0.0X PRESSURE CANNOT BE ACHIEVED OR IT DID NOT HOLD/ ISOLATE FOUR WAY
a) Figure right, clamp BOTH Four-Way Dialysate Line tubing
segments!
b) Can you achieve -250 mmHg and does it
HOLD it, +/- 15 mmHg, for one (1) minute
now. TWO (2) possible scenarios below:
1) IF still CANNOT achieve -250 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 AUTOTEST- 3.1.0 (page 575).
2) IF you CAN achieve -250 AND it HOLDS: See parts A THROUGH E below:
A) Turn the machine OFF!
B)
Remove BOTH clamps from the Four -Way dialysate line segments!
C) Return to Dialysis Program (“Select Program” → ‘Dialysis’ → ‘Enter’).
D) From the Home screen, set [Dialysate Flow] to “OFF” and press ‘Enter’.
E) Proceed to
page 509, procedure number TMP- 4.0.0.
