vPad-A1 OPERATORS MANUAL
4.6.3.4 Artifact
The
Artifact
dropdown menu displays a selection of noise signals that can be
superimposed over the normal
SpO2
signal. An
Artifact
can be used, for
instance, to test the ability of an oximeter to function correctly in a noisy
environment.
4.6.4 Alarm Tests
The
SpO2 Alarm Test
checks a pulse oximeter for its ability to respond to an
Alarm
Condition
, such as a sudden drop in
Blood Oxygen Saturation
or a deteriorated
patient signal. There are four stages in an
Alarm Test
: 1) Test Setup; 2) Alarm State;
3) Alarm Stablization; and 4) Recovery.
4.6.4.1 Test Setup
The setup stage begins as soon as the
SpO2
module is launched from the
tabbed toolbar on the A1
Main
screen. At this time, users should make sure
that the pulse oximeter is displaying stable measurements in agreement with
the active settings of
Figure 68
, and that an alarm is not currently active.
This initial state is called the
Normal Condition
.
The button launches the
Alarm Test
setup interface. By
default, the screen will display the
Normal Condition
as copied from the
SpO2
parameter setup which is currently in use, per
Figure 68
.
The upper dropdown menu includes a list of
Alarm Test
types (
Figure 72
).
When a test type is selected, the setup interface enables only the controls that
are relevant for that specific
Alarm Condition
.
