Biomedical Test System

SPO2 Module

You should now observe the readings on the pulse oximeter for SPO2 and
heart rate. You can enter test results in two ways:

You can make a judgment yourself and press

F1 PASS

FAIL

to store with the record. FAIL is stored with a "#".

Or you can press

F3 DATA

to enter the actually observed pulse

oximeter readings into the medTester using the numeric,

UP/DOWN

, and

LEFT/RIGHT

keys, followed by

ENT

to complete.

Now the medTester will compare entered data to the preset
limits for SPO2 and heart rate. If any readings are out of
limits, the medTester will note that and give you a chance to
repeat the test.

SPO2 Alarm Test

This test measures how long it takes for the pulse oximeter to alarm after the
SPO2 goes to either a high or a low level.

First the medTester sets the SPO2 simulator to the programmed alarm
starting values for SPO2, heart rate, and amplitude. After settling, you can
press

F5 START

to go to the programmed high SPO2 alarm value. The

medTester then sets the SPO2 simulator to the high alarm value and waits for
you to press

when the pulse oximeter alarms, thus recording the time taken

to alarm. The results are displayed and the option is offered to repeat the test
if desired.

Next the low SPO2 alarm is tested in the same way.

Rate Alarm Test

Similarly, the rate alarm test is performed for high and low rates.

Asystole Test

Similarly, the asystole alarm is tested. For this test the amplitude is set to zero
percent to go to asystole.

Amplitude Test

This test measures what amplitude is the minimum that can be detected by
the pulse oximeter.

First, the medTester sets up the starting alarm test values, except amplitude is
set to start at ten percent. You are prompted to find the threshold that is the
lowest amplitude that will still be recognized by the pulse oximeter.

You can use the

UP/DOWN

keys to change the amplitude display on the

medTester, then you must press

F5 APPLY

to command the SPO2 simulator

to move to the new amplitude. When you find the threshold, press

F5 STORE

to record the results.
