CAUTION

Should an instrument be dropped or severely jarred, remove it from use immediately. It should

be thoroughly tested and inspected by qualified service personnel to ensure proper function prior to reuse.

2.1 INTRODUCTION

SpO

This chapter describes initial

Module

setup and configuration. Due to product changes over time, configurations described in this chapter may differ from the instrument being serviced.

2.2 NEW INSTRUMENT CHECKOUT

Prior to placing a new instrument in use, perform a check-in procedure using the Maintenance Software.

When powering up the instrument, verify the instrument beeps and all display segments flash. This confirms that the instrument has performed its self test and is operating correctly. During operation, the instrument continually performs a self test, and alarms and displays a message if it detects an internal malfunction.

Contact CareFusion authorized service personnel if the instrument has physical damage, fails to satisfactorily pass the startup sequence, fails a self test, or continues to alarm.

4.1 INTRODUCTION

This chapter describes the

SpO

Module

principles of operation. Reference the PC Unit / Pump Module

8000/8100 Series) Technical Service Manual

( for Alaris

System principles of operation.

4.2 GENERAL INFORMATION

SpO

Module operation is based

on the principles of pulse oximetry. Oxyhemoglobin and deoxyhemoglobin differ in their absorption of red and infrared light (spectrophotometry). The volume of arterial blood in tissue and the light absorbed by the blood changes during the pulse (plethysmography).

Because oxyhemoglobin and deoxyhemoglobin differ in light absorption, the amount of red and infrared light absorbed by blood is related to hemoglobin oxygen saturation.

4.3 8210 Series (Nellcor Technology)

SpO

A pulse oximeter determines

passing red and infrared light into an arteriolar bed and measuring changes in light absorption during the pulsatile cycle. Red and infrared low-voltage light-emitting diodes (

LED) in the oximetry sensor serve as

light sources; a photo diode serves as the photo detector.

To identify the oxygen saturation of arterial hemoglobin, the monitor uses the pulsatile nature of arterial flow. During systole, a new pulse of arterial blood enters the vascular bed, and blood volume and light absorption increase. During diastole, blood volume and light absorption reach their

SpO

lowest point. The

SpO

measurements on the difference

Module bases its

between maximum and minimum absorption (measurements at systole and diastole).

Alaris® SpO2 Modules

Technical Service Manual

4-1

PRINCIPLES OF OPERATION

4.3 8210 series (Nellcor Technology)

(Continued)

By doing so, it focuses on light absorption by pulsatile arterial blood, eliminating the effects of nonpulsatile absorbers (such as, venous blood, tissue and bone).

Because light absorption by hemoglobin is wavelength dependent and the mean wavelength of

LEDs varies, an oximeter

must know the mean wavelength of the sensor’s red

SpO

. During monitoring, the instrument’s

LED to accurately measure

software selects coefficients that are appropriate for the wavelength of that individual sensor’s red

LED. Those

coefficients are then used to determine

SpO

To compensate for differences in tissue thickness, the light intensity of the sensor’s

LEDs is adjusted automatically.

The

SpO

Module measures functional

saturation (oxygenated hemoglobin expressed as a percentage of the hemoglobin that can transport oxygen). It does not detect significant amounts of dysfunctional hemoglobin (such as, carboxyhemoglobin or methemoglobin). In contrast, hemoximeters (such as,

IL482)

report fractional saturation (oxygenated hemoglobin expressed as a percentage of all measured hemoglobin, including measured dysfunctional hemoglobin).

To compare functional saturation measurements to those from an instrument that measures fractional saturation, fractional measurements must be converted as follows:

functional saturation =

fractional saturation

100 - (%carboxyhemoglobin + %methemoglobin)

When saturation is calculated from a blood gas partial pressure of oxygen

x 100

), the calculated value may differ

(

SpO

from the

measurement of the SpO2

Module. This usually occurs because the calculated saturation was not appropriately corrected for the effects of variables that

shift the relationship between

and

pH, temperature, the partial pressure

PCO

of carbon dioxide (

), 2,3-DPG, and

fetal hemoglobin. To compare functional saturation measurements to those from an instrument that measures fractional saturation, fractional measurements must be converted as follows:

The Signal Extraction Technology

Module uses the Masimo®

(SET®) to decompose the red and infrared pulsatile absorbance signal into an arterial signal plus a noise component. Its value is used to find

SpO

the equation in the Masimo

saturation in an empirically derived

SET® software. The values in an internal look-up table are based on human blood studies against a laboratory co-oximeter on healthy adult volunteers in induced hypoxia states during motion and nonmotion conditions.

Chapter 7 – ILLUSTRATED PARTS BREAKDOWN

7.1 INTRODUCTION

The illustrated parts breakdown for the instrument is divided into major assemblies and individual parts.

7.2 ILLUSTRATIONS

The exploded views serve as visual aids for identifying the parts of each assembly. If a part/assembly is identified with an item number (appearing in a bubble), that number corresponds with the item number on the parts list. If a part/assembly is not identified with an item number, it is available only as part of a higher assembly or kit.

Due to product changes over time, components/assemblies illustrated in this chapter may differ from the instrument being serviced.

7.3 PARTS LIST

The parts list provides the following information for saleable parts and assemblies:

Item: This number corresponds with number in illustration.

Part Number: This is the Alaris

number needed when placing an order. When a part number is not provided, that

part is either not sold by CareFusion, is provided as part of a kit or higher assembly, or can only be replaced/repaired by CareFusion authorized service personnel.

Description: Descriptive information that may be helpful when placing an order.

QTY: Total number of each item used.
