PHT- 2.2.0 CHECK UF PUMP SIGNAL / FLUID OUTPUT
a) Call debug screen 0 and locate the UF pump and its adjacent dot (see Figure right).
b) Referring to the Figure (below, right), remove the Fluid Sample Connector from the
Fluid Sample port and position it so that it can be observed.
c) When (and ONLY when) the "Get Neg TMP" message is
present AND TMP is less than 220 mmHg AND there are NO
alarms the UF dot should blink** white – blue – white,
approximately every
** NOTE: If (and ONLY if) the dot NEVER blinks proceed to
page 215, SECTION 14 – UF PUMP
d) When (and NOT until) the UF dot blinks white-blue are there
'strong fluid pulses' through the Fluid Sample Connector?
Yes Return the Fluid Sample Connector and see procedure number
No Proceed to page 215,
PHT- 3.0.0 CHECK TMP INCREASE
Does TMP reach 220 mmHg or greater in one more minute or less?
Yes See procedure number
No a) Turn the machine off and back on.
b) Return to Dialysis Program (remember to press the 'CONFIRM' key) then see procedure
number
PHT- 4.0.0 VERIFY THE PRESSURE TESTS
Allow the tests to complete. Ignore test Failures above Negative Pressure! Two scenarios:
1) Negative and/or Positive Pressure Test FAILS: See procedure number PHT- 5.0.0 (page 195).
2) BOTH Pressure Tests (Negative and Positive) PASS: See procedure number PHT- 4.2.0 (page
194).
PHT- 4.2.0 REPEAT PRESSURE TESTS
From the 'Test & Options' screen, select the 'Pressure Test' button then press the 'CONFIRM' key to
repeat Pressure Tests. Two scenarios:
1) The "Get Neg TMP" message lasts longer than two minutes: Return to procedure number
2.2.0 (page 194).
2) The "Neg Flow On" message appears within two minutes: Do BOTH pressure Tests (Negative
and Positive) pass again?
