PHT- 5.6.0 CHECK PDIAL AT 0 mmHG / PERFORM POSITIVE TEST
a) Using the syringe set pressure on the external meter to 0 mmHg. If (and ONLY if) PDial does NOT =
0 +/- 25 see procedure number
b) Push on the syringe plunger. Are you able to create approximately +250 mmHg AND HOLD it (+/- 20
mmHg per minute) on the external meter?
Yes a) Remove the tubing and syringe from the P
b) Return the dialyzer lines to the shunt and close the door.
c) See procedure number
No Remove the tubing and syringe from the P
(page 199).
PHT- 7.0.0 CHECK AIR REMOVAL SYSTEM
a) Turn Dialysate flow off (Dialysate flow on/off LED blinks) and
allow one minute for the deaeration pump to stop.
b) Referring to the Figure (right), tee a gauge to the INPUT
(clear tubing) of the deaeration pump.
IMPORTANT!
c) Turn Dialysate flow ON (Dialysate flow
on/off LED off).
d) Referring to Appendix A
okay?
Yes See procedure number
No See procedure number
PHT- 7.1.0 CALIBRATE DEAERATION PRESSURE
Calibrate DEAERATION AND LOADING PRESSURE per procedure. Is the calibration successful?
Yes See procedure number
No Proceed to page 211,
PHT- 7.2.0 REPEAT PRESSURE TESTS
a) Return to Dialysis program (remember to press the 'CONFIRM' key).
b) Allow up to eight minutes for Temperature and Conductivity to stabilize.
c) Call the Home screen and assure Venous Pressure = 0 mmHg.
d) Clear all alarms Select the screen's 'Test & Options' button.
e) Select the 'Both Tests' button then press the 'CONFIRM' key.
f) Allow the tests to complete. Ignore test Failures above Negative Pressure! Two scenarios:
1) Negative and/or Positive Pressure Test FAILS: See procedure number
2) BOTH Pressure Tests (Negative and Positive) PASS: Repeat the Pressure Tests. If they pass
again calibrating deaeration fixed the problem. If (and ONLY if) either fail see procedure number
