1. About PRO-Soft QA-510

1.1 Introduction

Pulse Oximetry is a state-of-the-art, non-invasive method to deter-

mine the percentage of a patient's oxygen saturation (SaO

) without

having to obtain an arterial blood specimen. The instrument used for

this determination is a pulse oximeter. An oximeter measures the

changes in the intensity of transmitted light as blood pulsates through

a patient's finger or earlobe. From this data, the pulse oximeter does

mathematical calculations to determine the percentage of oxygen

saturation of the blood.

METRON’s QA-510 SpO

Analyzer is a precision instrument for

testing these oximeters, and is designed for use by trained service

technicians. It allows the user to:

• Simulate a variety of environmental and patient conditions.

• Measure a pulse oximeter’s infrared and red LED.

• Check the pulse oximeter’s ability to generate an alarm when

SpO

or heart rate exceeds specified limits.

Testing with the QA-510 is usually a matter of setting up the pre-

ferred simulation parameters. Using PRO-Soft QA-510 simplifies the

process by providing an all Windows-based environment through

which simulation parameters are created by the user and sent to the

QA-510 unit. This in turn activates the corresponding simulation

state through the QA-510 Finger.

Testing

PRO-Soft QA-510 performs tests based on user generated test se-

quences and checklists. With the sequence tests you can perform sim-

ple or complex tests, including both the single and alarm limits test

modes, can be created and executed semi-automatically.

Test results are entered on the screen during testing. At the conclu-

sion of testing the user may print a report, store the tests and results

on disk, or both. Combinations of tests can be created and stored as

“sequences.” PRO-Soft QA-510 maintains a library of these se-

quences. In this way the user can store and retrieve sequences that are

appropriate for the kind of equipment being tested.

Sequences can then be used independently, or can be attached to a

checklist, written procedure, and equipment data in the form of a test
