vPad-A1 OPERATORS MANUAL
4.7.4 Over Pressure and Pop-Off
The
Over Pressure
feature is intended to test the pressure relief valve limits in an
NIBP
monitor. A typical test routine involves pumping air into the pneumatic
system until the high pressure triggers the relief valve, which will then vent the
system to a safe pressure level.
Over Pressure
parameters are not active during setup. Access the feature setup
page by swiping right from the
Pressure
page (
Figure 82
) or swiping left from the
Leakage Rate
page (
Figure 91
), then press when ready.
4.7.4.1 Target Pressure
The
Target Pressure
parameter controls the highest pressure reached during
an
Over Pressure
test. This is generally the maximum acceptable relief
pressure for the safety valves. It can be set from 0 to 400 mmHg, in 1 mmHg increments.
4.7.4.2 Release Time
The
Release Time
designates the amount of time allowed for the pressure relief valves to vent
system pressure to a safe level. This value is generally specified by the manufacturer of the monitor.
It can be set from 1 to 999 seconds, in 1 second increments.
4.7.4.3 Running Over Pressure Tests
Before starting an
Over Pressure
test, first place the NIBP monitor in
service mode or pop-off/relief pressure test mode, as appropriate. When
setup is complete, the
button will intiate the test and show the
Result
screen.
In the
Result
screen, the
Target Pressure
parameter is displayed as “Pop
Off Pressure”. The result assignment (PASS/FAIL) buttons are disabled
while inflation and pressure relief is in progress, as indicated above the
Comments
box by a spinning wheel .
The button can abort the
Over Pressure
test at any time when
it is busy. The test can then be restarted with the button.
