3.1 INTRODUCTION

Perform regular and preventive
maintenance inspections to ensure that the
EtCO

Module remains in good operating

2

condition:

• Perform regular inspections before each
use.

• Perform preventive maintenance
inspections annually.

These requirements and guidelines are
intended to complement the intent of Joint
Commission on Accreditation of Healthcare
Organizations (

JCAHO) requirements.

3.2 REGULAR AND PREVENTIVE
MAINTENANCE INSPECTIONS,

Use the Maintenance Software (version 7 or
later) to perform calibration and preventive
maintenance.

Contact CareFusion Technical Support if
you need help obtaining or using the

4 PRINCIPLES OF OPERATION

Chapter 4 — PRINCIPLES OF OPERATION

4-1Alaris

®

EtCO2Module (8300 Series)

Technical Service Manual

4.1 INTRODUCTION

This chapter describes the principles of
operation for the EtCO

2

Module and its

major subsystems.

Refer to the PC Unit/Pump Module
Technical Service Manual for Point-of-Care
Unit information.

4.2 GENERAL INFORMATION

The EtCO

2

Module uses Oridion’s patented

Microstream

®

non-dispersive infrared (NDIR)
spectroscopy to continuously measure the
amount of CO

2

during every breath, the

amount of CO

2

present at the end of

exhalation (EtCO

2

) and during inhalation

(FiCO

2

), and the Respiratory Rate. The

EtCO

2

Module is a side stream capnograph.

The Microstream

®

Disposables deliver a
sample of the inhaled and exhaled gases
from the ventilator disposable or directly
from the patient (via an oral/nasal cannula)
into the monitor for CO

2

measurement.
Moisture and patient secretions are
extracted from the sample by the
Microstream

®

inline filter while maintaining

the shape of the CO

2

waveform.

The 50 mL/min sampling flow rate reduces
liquid and secretion accumulation,
decreasing the risk of obstruction in the
sample pathway in humid ICU
environments. The small sample size
required by Microstream

®

eliminates the
need for water traps and prevents excess
fluid accumulation.

The EtCO

2

Module draws a gas sample
through a microsample cell (15 microliters).
This extremely small volume is quickly
flushed, allowing for a rise time of

PRINCIPLES OF OPERATION

4-2

Alaris®EtCO2Module (8300 Series)

Technical Service Manual

approximately 190 ms and accurate CO

2

readings, even at high respiration rates.

The Microbeam IR source illuminates the
microsample cell and the reference channel.
This proprietary IR light source generates
only the specific wavelengths characteristic
of the CO

2

absorption spectrum. The IR light
that passes through the microsample cell
and the IR light that passes through the
reference channel are measured by IR
detectors.

The microcomputer in the EtCO

2

Module

calculates the CO

2

concentration by

comparing the signals from both channels.

No operator intervention is required for
routine moisture or condensate.

All Microstream

®

Disposables contain an
inline hydrophobic filter to extract
condensate and/or patient secretions while
maintaining measurement and waveform
integrity. For humid conditions within the
operating parameters of the EtCO

2

Module

and Microstream

®

Disposables, humidity

has no quantitative effect on the CO

2

concentration, given the small 50 mL/min
sample size rate. In high humidity
environments or extended monitoring
periods (24-72 hours) only Microstream

®

Disposables designed for those instances
should be used. In the event of humidity or
condensate outside the EtCO

2

Module’s

operating specifications, the EtCO

2

Module
will present a “Remove Blocked Disposable”
message.

Due to the relatively small sampling size
needed for EtCO

2

readings, partial pressure

does not affect the ability of the EtCO

2

Module to measure EtCO2, as long as the
50 mL/min rate can be achieved.

Microstream

®

Disposables are single-use,
disposable devices which must be changed
with each use. The manufacturer’s sample
flow, 50 mL/minute, does not affect the
disposable’s life; however, humidity and
specific patient conditions may shorten the
effective life of the disposables.
Microstream

®

Disposables are rated for up
to 24 hour and 72 hour use, depending on
the specific Microstream

®

Disposable.

The EtCO

2

Module provides readings in
compliance with BTPS (body temperature,
pressure, saturation) standards. There is no
effect on accuracy due to cyclic pressure up
to 10 kPa.

NOTE: BTPS (body temperature, pressure,

saturation assumed 37°C, 47 mmHg)
calculations are made according to:

PCO2= FCO2X (Pb - 47)

Where:

FCO

2

is the fractional concentration of CO

2

in dry gas, and FCO2= % CO2/100.

Pb is the ambient pressure.
PCO

2

is the partial pressure of CO2at

BTPS.

Technical Service Manual

Chapter 5 — CORRECTIVE MAINTENANCE

WARNING

Disconnect the EtCO2Module from the Alaris

®

System before performing maintenance. qualified
personnel using proper grounding techniques
should open the instrument case.

CAUTION

CMOS devices are sensitive to static electrical

charges and may be damaged during repair if the
repair activity is not performed in an electrostatic
discharge (

ESD) protected environment using

approved ESD protective procedures, including
personnel grounding.

NOTE: Due to product changes over time,

components/ assemblies illustrated in this chapter
may differ from the instrument you disassemble. If
there are any questions, look for Service Bulletins
related to this chapter or contact CareFusion
Technical Support.

5.1 INTRODUCTION

This chapter describes how to disassemble
and reassemble the EtCO

Module.

2

For more efficient repair, read the “Principles
of Operation” chapter for information on the
mechanical and electrical functions of the
EtCO

Module.

2

The surface mount devices on the circuit
boards are not field repairable. Return
circuit boards to an authorized CareFusion
Service Center for repair. Attempting
circuit board repairs voids all warranties.

Whenever the EtCO2Module is repaired,
perform the minimum tests required for new

instrument checkout (use Maintenance
Software v

7 or later).

For information on replacement parts, see
the “Illustrated Parts Breakdown” chapter.

Following any level of maintenance, perform
the applicable tests (refer to “Level of
Testing Guidelines” table).

Follow these procedures in order for the
most efficient disassembly of EtCO

2

Module

subassemblies. To reassemble the EtCO

2

Module, reverse the disassembly steps.

NOTE: Perform all maintenance on an

antistatic surface, preferably a grounded
antistatic mat.

Before adhering gaskets and labels to the
instrument, clean the surface with a cotton
swab or soft cloth lightly dampened with

70% Isopropyl Alcohol.
