vPad-IV OPERATORS MANUAL
Enter the upper pass/fail pressure limit of the test according to the manufacturer's inspection procedure or
alternatively per the performance specifications of the device under test. Optionally, you may also enter a
lower pass/fail limit for a
minimum
pressure that the infusion device must reach by the end of the test.
Disable this minimum limit by entering zero, or otherwise refer to the manufacturer's protocol when
inputting a value for the lower limit.
For best results, the pressure reading should be zeroed before the test is started. Follow the guidance
specified in Section 4.3.3.6 on page 31 when zeroing the pressure. If the vPad-IV Module is primed,
hydrostatic pressure or vacuum external to the unit may offset the zero calibration. Inaccuracy of the
pressure zero can be eliminated by draining the Module and opening the input to the atmosphere while the
setup menu for the Occlusion Pressure Test is being viewed. Once the Module has been emptied, and with
the input port open to the air, press the
Zero button on the menu to capture an accurate zero reference.
After zeroing, the Module may be refilled and the test started. If the purpose of the test is to check the
pressure transducer in the Module rather than test an infusion device, it is not necessary to refill the Module
with water; in this case, verification of the Module's pressure measurement may be optionally performed
with compressed air.
Users can stop an occlusion pressure test in progress at any time, even before the automatic stop condition
is reached. Normally, you will stop the test when the infusion device senses the downstream occlusion and
produces an audio-visual alarm. The peak pressure observed during the test, as well as the 'alarm' pressure
observed when the test is stopped, are saved in the Test Record.
4.3.8 AutoSequence Test
A vPad-IV AutoSequence is a customizable series of user instructions, visual inspections or "checks", and
one or more pre-configured tests of Flow Rate, Piggyback, PCA or Occlusion performance as described
above. Choosing the AutoSequence option in the test setup menu will open a selector that lists all
AutoSequences available on the tablet. Begin running an AutoSequence by clicking on its name in the list.
See Section 4.8.6 on page 67 for details on how to create or modify an AutoSequence with the
AutoSequence Editor .
