Test Failure Screen - Fresenius Medical Care 2008T Operator's Manual

Chapter 2—Daily Preparation for Treatment
Individual tests are identified as shown on the "Test & Options" screen. A failure of any of
the tests is indicated by a red X in the error box to the right of the test name.
The Alarm test consists of nine individual tests that verify the integrity of the settable alarm
limits of the system. Both the alarm and pressure tests should be conducted by the operator
prior to each treatment.
The Pressure Holding Test (PHT) consists of two separate tests that are conducted
sequentially. The purpose of the PHT test is to ensure the pressure integrity of the hydraulic
system under actual pressures generated during the normal operation of the system. PHT
must be performed before each high-flux treatment.
If all tests are completed successfully, a message TEST COMPLETE appears in the Status
box. The operator must press RESET once to clear the message. Patient-specific treatment
parameters (other than UF related) can be entered at any time during the test.
An audible alarm sounds only if a test has failed. In a failure situation, after all of the tests
have been completed, the message BOTH TESTS FAILED, ALARM TEST FAILED, or
PRESSURE TEST FAILED is displayed in the Status box depending on the nature of the
failure. A red X appears in the failure box designating the test(s) failed. The right side of the
screen provides additional information regarding the failure. A description of the test
messages can be found in Chapter 6, "Troubleshooting". Pressing the RESET key once
mutes an alarm, pressing it a second time resets the right side of the screen.
