vPad-A1 OPERATORS MANUAL
For example, in
Figure 71
, only
SpO2%
is enabled for the “Low Saturation” test type since it is the
critical parameter responsible for this
Alarm Condition
. Users may adjust the parameter to a level
that will trigger an alarm from the pulse oximeter. All other parameters are fixed and must remain
the same as for
Normal Condition
.
Unlike the regular
SpO2
setup interface, changes in
Alarm Test
setup are not reflected immediately in
the generated oximetry signals. The
Alarm Condition
will be applied after the
Alarm Test
begins.
When test setup is complete, the button launches a new test interface that guides users
through the chosen
Alarm Test
. The screen displays a summary of both the
Normal Condition
and
the
Alarm Condition
. A single action button appears near the centre of the interface:
When pressed in this initial state, the action button will apply
the
Alarm Condition
. The test enters the Alarm State.
4.6.4.2 Alarm State
The “Time to Alarm” box will begin counting up in number
of seconds. This keeps track of the amount of time required
for the pulse oximeter to respond to the
Alarm Condition
.
Pressing the button in this state indicates that the expected
alarm has been triggered. The “Time to Alarm” timer stops,
and the
Alarm Test
enters Alarm Stablization.
4.6.4.3 Alarm Stablization
Once the alarm has been triggered, the
Alarm Test
pauses to
allow the
Alarm Condition
to stablize. During the Alarm
Stablization stage, the action button is disabled. Instead of an
action, it displays a countdown of five seconds. When
countdown is complete, the
Alarm Test
enters Recovery.
