vPad-A1 OPERATORS MANUAL
The buttons in
Figure 105
change the selected point's
pressure, and buttons change its amplitude.
The AMAP button displays the current maximum pulse height, which
defines the largest simulated pulse that vPad-BP will produce during
an NIBP Simulation. If the device requires smaller pulses (e.g. the
test cuff is smaller than the typical adult cuff), then the AMAP
controls can be used to adjust the maximum pulse height as needed.
The
Shift controls move the entire Envelope horizontally along the pressure axis. Pressing a or
button moves all inflection points by the same pressure shift. The default increment is 10
mmHg of pressure, though users can enter any custom number from 0 to 50 in the input box.
Changes to the Shift increment will only be applied after pressing the "Done" button on the
keyboard.
Pressing the button in
Figure 103
dismisses the tool and returns to NIBP simulation
settings after warning users of unsaved changes.
After users have verified via the button that the displayed
Envelope produces the expected readings on the target device, the
button will launch a “Save Envelope” form.
The form is pre-populated with information extracted from the
Envelope template originally selected for editing. The Manufacturer
and Model fields should contain the device make and model,
respectively, both of which can be edited if necessary.
Pressing the Mode button toggles between "Adult" and "Neonatal"
mode. This should be determined by the targeted monitor type and
settings used during
Envelope customization.
The
Targets fields contain three NIBP measurements (SYS-DIA-
MAP) that will later inform users on what blood pressure readings
they should expect from a properly-functioning device of the same
make and model. The automatically generated Envelope name,
which will be listed in the Simulation dropdown menu, is derived
from the entered Targets.
Pressing in
Figure 106
saves all displayed pressure parameters to an Envelope file. If
none of the fields in the form were edited, then the originally chosen template will be overwritten.
