vPad-A1 OPERATORS MANUAL
4.7.3 Pressure Source and Manometer
The
Pressure Source and Manometer
(
Pressure
) feature can be used to verify the
pressure transducers in a
NIBP
monitor, or other pressure-measuring devices.
Pressure
parameters are not active during setup. Access the feature setup page by
swiping right from the
NIBP Simulation
page (
Figure 76
) or swiping left from the
Over Pressure
page (
Figure 88
), then press
when ready.
4.7.3.1 Mode
The
Pressure
module has three
Modes
of operation.
•
Auto
- Inflates and regulates system pressure
•
Manual
- Passively measures system pressure
•
Step
- Inflates pressure in regular steps until it reaches the target pressure
4.7.3.2 Maximum Pressure
The
Maximum Pressure
parameter refers to the highest target pressure for
Auto
and
Step
regulation.
It can be set from 10 to 400 mmHg, in 1 mmHg increments. Parameter controls are disabled in
Manual Mode
, since users and/or the
DUT
are in control of system pressure.
4.7.3.3 Delay Time
The
Delay Time
controls the pause duration between intermediate pressure
levels in
Step Mode
. It can be set from 1 to 600 seconds, in 1 second
intervals. Parameter controls are disabled in
Auto
and
Manual Mode
.
4.7.3.4 Pressure Step
The
Pressure Step
parameter sets the size of each intermediate pressure
interval in
Step Mode
. It can be set from 10 to 400 mmHg, in 1 mmHg
increments. Parameter controls are disabled in
Auto
and
Manual Mode
.
For example, in
Figure 83
, the setup page is in
Step Mode
. Once the test is
started, A1 will inflate system pressure from zero to the
Maximum Pressure
of 100 mmHg. In the process it will pause for 5 seconds
Delay Time
at
every 20 mmHg
Pressure Step
.
