vPad-A1 OPERATORS MANUAL
The button can abort the
Leakage Rate
test at any time. The test can then be restarted
with the button on the setup page.
At the beginning of an
Auto Mode
test, the A1 will begin pumping air into the pneumatic system
until pressure reaches
Start Pressure
. The
Test Time
countdown will automatically start after the
target pressure is reached.
In
Manual Mode
, any incoming pressure must be from an external source (i.e., from the NIBP
monitor itself, or alternatively from a hand pump). When pressure reaches the desired level, then
users can start the
Test Time
countdown by pressing the button on the
Result
screen.
For both
Modes
, the button is initially disabled; however, users can assign if, for
example, it becomes clear that a system leak is too large to reach
Start Pressure
. Otherwise, the
PASS result will be available at the conclusion of the test.
When
Test Time
expires, the A1 measures the pressure one last time, then
vents the pneumatic system. The test will then calculate and display the
Leakage Rate
in mmHg per minute.
