vPad-IV OPERATORS MANUAL
pca
Runs a PCA Pump Test with settings for bolus volume, basal rate and lockout as shown by
the editor. On completion of the
pca step, a summary of the measurement results is saved
in the Test Record.
occl
Runs an Occlusion Pressure Test with settings for pressure limits and test duration as
shown by the editor. Optionally, the test can be configured to maintain the pressure in the
channel after the test is completed; this mode is useful for testing devices which may
provide multiple occlusion pressure limits or thresholds. On completion of the
occl step, a
summary of the results is saved in the Test Record.
backpr
Displays real-time readings of pressure as measured by the channel, so that a back pressure
or vacuum being applied externally to the infusion device can be adjusted before a Flow
Rate or other test commences. The back pressure measured by this step is saved to the Test
Record. For further details on back pressure setup, see Section 3.5.2 and
Figure 16 on page
20.
prmon
Similar to back pressure, the pressure monitor shows real-time pressure readings while
displaying the average, maximum and minimum value of the pressure. The user may
manually control whether the channel input is blocked or occluded, or otherwise remains
open. Average, maximum and minimum pressures are saved to the Test Record when the
step is completed.
Further details of the above step types, in particular how these steps will appear and function during
execution of the sequence, are given in "Running Pump Tests" (Section 4.5, page 44) and "AutoSequence
Steps" (Section 4.5.6, page 49).
When a new step is added to the sequence, the step is initilized to default settings. Clicking the
Edit
button
opens the step editor to enable customization.
4.8.6.4 Step editors
Each step type has an associated editor that allows users to control appearance and behaviour of the step.
Test-related step editors enable users to configure test settings such as rate, volume-to-be-infused (VTBI),
stop condition and pass/fail tolerance.
Prompt Editor
During sequence execution, a
prompt
step displays instructions to
the user and/or other information. The prompt text can be freely
customized, and formatted with
bold
type for emphasis or
small
type for longer messages or detailed instructions. The text is center-
justified for normal and
bold font, and left-justified for
small
font.
