To test the alarms:
SpO
2
Test
The following procedure tests the performance of the SpO
2
measurement and alarm.
To perform this test, you need an adult SpO
2
sensor.
To perform the SpO
2
test:
Caution A functional tester cannot be used to assess the accuracy of a pulse oximeter
monitor. However, if there is independent demonstration that a particular
calibration curve is accurate for the combination of a pulse oximeter monitor and a
pulse oximeter sensor, then a functional tester can measure the contribution of a
monitor to the total error of a monitor/sensor system. The functional tester can
then measure how accurately a particular pulse oximeter monitor is reproducing
that calibration curve.
Step
1
With the monitor turned on, make sure that all alarms are enabled (the
monitor is not in Audio Pause or Audio Off mode).
2
Make sure the NBP alarm is enabled (the crossed bell icon does not
appear in the NBP numeric pane).
3
Connect the NBP hose to the NBP input connector, but do not place the
cuff on your arm.
4
Press the NBP key on the front panel.
5
Wait for the NBP module to cycle and check that an NBP error message is
displayed in the message area and an alarm tone sounds.
6
If you do not get the results in step 5, see “NBP Problems” on page 4-6.
Note — Philips employees record this value as AL:P or AL:F.
Step
1
Connect an adult SpO
2
sensor to the SpO
2
connector on the monitor.
Ensure that the red LED in the sensor is lit.
2
Connect the other end of the sensor to your finger.
3
Verify that the SpO
2
value displayed on the monitor is between 95% and
100%. If it is not, try the test again with a patient simulator.
4
If you still do not get the results in step 3, see “SpO
2
Measurement
Problems” on page 4-7.
Note — Philips employees record this value as SpO
2
:P or SpO
2
:F.
