Service Policy
Novametrix Medical Systems Inc. will provide Warranty Service Support to its customers within 48
hours of receiving a telephone request for technical support. This 48 hour period begins once a
service request is placed through the Factory Technical Support Department in Wallingford,
Connecticut. Novametrix provides factory direct technical support to its customers through a
technical support group located in Wallingford, Connecticut and company service representatives
located throughout the United States. All Technical Support for Novametrix products is provided
“Factory Direct”.
Novametrix provides 24 hour a day technical support accessibility via telephone numbers (800) 243-
3444 or [phone]. After hours technical support requests (before 8:00 AM and after 5:00 PM
Eastern Time) will be responded to promptly by the Technical Support On-Call staff. It is suggested
that any person calling in for technical support have the inoperative equipment available for
preliminary troubleshootingas well as product identification.Novametrix reserves the right to repair
or replace any product found to be defective during the warranty period. Repair may be provided in
the form of replacement exchange parts or accessories, on-site technical repair assistance or
complete system exchanges. Repairs provided due to product abuse or misuse will be considered
“non-warranty” and invoiced at the prevailing service rate. Any replaced defective material is
expected to be returned to Novametrix within 10 days of being provided in order to avoid additional
charges. Exchanged material should be returned promptly and directly to Novametrix using the
return paperwork and shipping label(s) provided. Transferring return materials to local sales or
dealer representatives does not absolve return responsibility.
Novametrixmanufactures equipment that is generally “user serviceable” and canusually be repaired
with the replacement of a plug-in electro-mechanical assembly by the clinical end user. When repair
parts are provided, the recipient can call into Novametrix for on-line replacement assistance and
repair assurance. In the event a replacement part requires increased technical capability, Technical
Support may request Biomedical assistance, provide on-site technical support or complete
replacement equipment. If the customer requires the return of their original product, the exchange
material will be considered “loaner material” and exchanged again after the customer equipment is
repaired.

Rev. 04 CO2SMO User’s Manual 3
Section 1 Introduction
The Novametrix CO2SMO ETCO2/SpO2Monitor, Model 7100, is a lightweight, easy to use, combination
capnograph and pulse oximeter monitor designed for use in a variety of clinical settings. It provides
reliable measurement, display and alerts for, end tidal carbon dioxide (ETCO2), respiration rate,
functional pulsatile oxygen saturation (SpO2) and pulse rate. The included sampling system allows CO2
monitoring of non-intubated patients.
Numerical and waveform information is presented on a bright Cold Cathode Display (CCD) with user
adjustable contrast to optimize viewing angles. A simple menu system allows user selection of
measurement and display options. Alerts are menu programmable or automatic. Presence of a pulse is
indicated audibly by a user-selectable “beep”.
Separate 24 hour trends for ETCO2, respiration rate, SpO2and pulse rate are updated every 8 seconds.
Trend “events” and audible alarm status (Audio Off) are also stored in trend memory.
CO2SMO has a serial port (RS232) for interfacing to external equipment. The monitor can be powered
from the AC Mains or from its rechargeable two-hour battery.

Principles of Operation
CO2SMO measures carbon dioxide and respiratory rate with a unique solid-state device called a
CAPNOSTAT CO2Sensor. The CAPNOSTAT CO2Sensor is placed onto an Airway Adapter and the
airway adapter is placed in the patient’s airway circuit—typically between the ventilator elbow and the
patient wye (See “CAPNOSTAT CO2Sensor” on page 17.) Infrared light is generated in one leg of the
“U” shaped sensor and then beamed through the windows of the airway adapter to a detector in the other
leg of the sensor. Carbon dioxide, flowing in the airway adapter as a result of respiration, absorbs some
of this light energy. The monitor relates the amount of detected energy to the amount of CO2in the
sample cell (the airway adapter). This results in a capnogram display and numerical values for CO2and
respiration rate. CO2SMO uses an adaptive digital detection algorithm system incorporating highly
accurate digital filters and adaptive thresholds to cover a wide range of monitoring situations including,
rebreathing, neonatal respiratory rates and CO2levels, and adult OR and ICU conditions without the
operator having to change monitor settings.
Respiration is calculated by measuring the time interval between detected peaks of the CO2waveform.
The inverse of this measurement is displayed as respiratory rate. Certain rebreathing circuits, or the
presence of artifact such as cardiogenic oscillations, may cause CO2SMO to react to non-respiratory CO2
fluctuations as if they were breaths—this condition affects only the numerical displays, the Capnogram
display continues to provide an accurate picture of the CO2waveform. A Respiratory Rate Editor can be
enabled to make the instrument more selective in its differentiation of waveforms caused by breathing
and those introduced by artifact. As a result, when the editor is in use, the monitor will adapt slowly to
sudden changes in respiratory rate.

Principles of Operation

SpO

Principles of Operation
CO2SMO measures oxygen saturation and pulse rate with sensors that contain red and infrared light
sources, called LEDs. Since oxygen saturated blood absorbs different amounts of light at each
wavelength (red and infrared) as compared to unsaturated blood, the amount of light absorbed by the
blood in each pulse can be used to calculate oxygen saturation.
The light energy from red (660 nm) and infrared (940 nm) LEDs is beamed through a sample cell—a
pulsating vascular bed, the patient’s finger or toe for example. The remaining light energy not absorbed
by the sample cell reaches a light receptor, called a photodiode, on the opposing side of the sensor. The
data received at the photodiode is sent back to the monitor where it is split into its red and infrared
components, digitized, processed by a microprocessor chip, and finally displayed as a numerical value
for oxygen saturation and a plethysmogram.
CO2SMO is calibrated to display “functional” saturation. This differs from the “fractional” saturation
value displayed by most co-oximeters
Functional saturation represents the amount of oxyhemoglobin as a percentage of the hemoglobin that
can be oxygenated. Dysfunctional hemoglobins (COHb and METHb) are not included in the
measurement of functional saturation.
Pulse Rate is calculatedby measuring the time interval between the peaks of the infrared light waveform.
The inverse of this measurement is displayed as pulse rate.
CO2SMO must be used in conjunction with SuperBright™ saturation sensors. An INCOMPSpO2 PROBE
message indicates a non-SuperBright™ Sensor is in use.
Functional Saturation = HbO2
100 - (COHb + METHb)
HbO2= Fractional Hemoglobin
COHb = Carboxyhemoglobin
METHb = Methemoglobin
