Introduction
The Novametrix CO2SMO ETCO2/SpO2 Monitor, 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, SpO2 and 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.
CO2 Principles of Operation CO 2SMO measures carbon dioxide and respiratory rate with a unique solid-state device called a
CAPNOSTAT CO2 Sensor. The CAPNOSTAT CO2 Sensor 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 CO2 Sensor” 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 CO2 in the sample cell (the airway adapter). This results in a capnogram display and numerical values for CO2 and 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 CO2 levels, 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 CO 2 waveform. 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 CO2 waveform. 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.

SpO2 Principles of Operation
SpO2 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
HbO2 100 - (COHb + METHb) HbO2 = Fractional Hemoglobin COHb = Carboxyhemoglobin METHb = Methemoglobin Functional Saturation =
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 calculated by 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 INCOMP SpO2 PROBE
message indicates a non-SuperBright™ Sensor is in use.
