vPad-A1 OPERATORS MANUAL
4.7.5 Leakage Rate
A
Leakage Rate
test assesses the rate at which air leaks from a pneumatic system,
typically by inflating up to and then holding a certain pressure for a predetermined
amount of time.
Leakage Rate
parameters are not active during setup. Access the feature setup page
by swiping left from the
NIBP Simulation
page ( Figure 76 ) or swiping right from
the
Over Pressure
page (
Figure 88
), then press when ready.
4.7.5.1 Mode
The
Leakage Rate
feature may operate in one of two Modes:
•
Auto
- Inflates to
Start Pressure
automatically
•
Manual
- Passively measures system pressure
4.7.5.2 Start Pressure
The
Start Pressure
parameter sets the initial pressure for the
Leakage Rate
test in
Auto Mode
. It
can be set from 20 to 400 mmHg, in 1 mmHg increments. This setting has no effect in
Manual
Mode
.
4.7.5.3 Test Time
Test Time
determines how long the
Leakage Rate
test will try to hold the
Start Pressure
in the pneumatic system without active regulation. It can be
set from 30 to 600 seconds, in 1 second increments.
4.7.5.4 Running Leakage Rate Tests
Before starting an
Over Pressure
test, first place the NIBP monitor in
service mode or manual valve control/leak test mode, as appropriate. When
setup is complete, users can initiate a test in the selected
Mode
and show the
Result
screen with the button.
In the
Result
screen, a progress bar
above the
Comments
box will indicate if the test is currently active.
