vPad-A1 OPERATORS MANUAL
Save R-Curve Data
• The button will save the entered R-Curve data to a new or existing device entry
as identified by the Manufacturer, Model, and (optional) Sensor fields on the menu.
• The button will discard all entered data without saving.
4.8.2.4 Calibration: NIBP Envelopes
NIBP simulations can be customized by touching the button on
the Settings screen. The button will launch a special NIBP Simulation setup interface similar to the
example of
Figure 76
, where it will be possible to select a Device and a Simulation (SYS-DIA-MAP)
from the dropdown menu. Pressing the Back button will return to the Settings screen.
Note
: The special NIBP Simulation setup interface does not allow navigation to other NIBP
features such as Pressure and Leakage Rate via the swipe gesture.
Each NIBP Simulation corresponds to an Envelope that is specifically customized for the chosen
Device. The Envelope contains parameters that allow the vPad-BP simulator unit to generate
precise pressure pulses during the course of a simulation test.
When creating an Envelope for a new or existing Device, it is generally
preferable to select as a starting point a set of simulation settings (including
Mode and Device) that already closely resembles the desired simulation.
Once an appropriate selection has been made for the template, touch the
EDIT icon to go to the Customize Screen as shown in
Figure 103
.
The “Customize Envelope” screen displays the selected Envelope and
targeted SYS-DIA-MAP readings in a graph. Various parameters in the
Envelope describe a relationship between the test system pressure
(horizontal x-axis) controlled by the NIBP monitor, and the height of
simulated pulses(vertical y-axis) as generated by vPad-BP.
The calibrated data points in an NIBP Envelope are also inflection points
where a “corner” changes the normally linear relationship between pressure
and amplitude, as shown in
Figure 103
. From left to right, the names of the
calibrated inflection points are:
