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.
