vPad-A1 OPERATORS MANUAL
4.1.3 Parameter Values and Options
Simulation settings may have anywhere from two choices (e.g. Adult vs. Neonatal ECG
Mode
) to hundreds
of possible values (e.g. ECG
Heart Rate
, adjustable from 20 to 360 BPM in 1 BPM steps). The manner of
user input depends on the number of choices available.
4.1.3.1 Button Controls
Typically, a parameter that has a limited number of possible settings will be
represented by a simple button accompanied by its title or description. An example of
a button control is
ECG Mode
. Touching the
Mode
button toggles the displayed text
between “Adult” and “Neonatal”. For parameters with more than two settings,
touching the button will cycle repeatedly through the available choices.
4.1.3.2 Numerical Input
A parameter which can be adjusted over a range of values may be represented by a group of icons as
shown in
Figure 20
, or alternatively as shown in
Figure 21
for certain parameters.
In either configuration, a button will display the current or active value of the parameter. Touching
the button displays a data entry menu, providing a set of
preset values from which to choose.
An example is the
ECG Amplitude
menu of
Figure 22
, which provides
eight preset selections. A vertical orange bar on the left of a preset button
indicates that it is the current, active value. Touching one of the preset
buttons will select the value shown on the button, and return the display to
the previous screen.
Some parameters have more choices than can be practically shown in a
group of buttons. An example is the
ECG Amplitude
parameter, for which
there are 32 choices but only 8 preset buttons on the menu. The message
“
Long press to change the preset value ” is a reminder that presets associated with
this parameter can be edited by the user to suit their needs or preferences.
If a value is desired that is not in the preset list, users have two options:
you can type the value into the “Enter Value” box and press “Accept”, or
change a preset button to the desired value so it can be used again later.
