Chapter 1: Technology Overview
The following chapter contains general descriptions about parameters, measurements, and the technology used in
Radius PCG.
Principles of Operation
The measurement of CO2in the breathing gas mixture is based on the fact that different gas components absorb
infrared light at specific wavelengths. A beam of invisible infrared light is directed through the respiratory gas flow in
the EMMA Airway Adapter. As the beam passes through the Airway Adapter, some of the light is absorbed by the gas
mixture. The amount of absorbed light is measured by a miniaturized two-channel spectrometer positioned to receive
the infrared light beam.
The spectrometer incorporates a filter wheel fitted with two different optical "color" filters. The wavelength ranges of
these filters are chosen such that one filters out colors where carbon dioxide has very strong absorption and the other
filters out colors where carbon dioxide has no absorption.
The spectrometer also incorporates an infrared detector that converts the light beam to an electrical signal. The
electrical signal is converted to a digital value that is fed to a microprocessor. The ratio of the light measured through
the two filters is then used by the microprocessor to calculate the carbon dioxide concentration in the breathing gas
mixture.

EMMA Airway Adapter
Respiratory gas measurements are, as described in the previous section, obtained by continuously measuring the
infrared light absorption through the EMMA Airway Adapter. The Airway Adapter is fitted with optical XTP™ windows
that are transparent to light in the wavelength ranges of interest. The Airway Adapter may, for example, be inserted
between the endotracheal tube and the resuscitation bag or between the resuscitation bag and the patient mask.
The Airway Adapter is available in two models: Adult/Pediatric and Infant. Radius PCG operates to specification with
either Airway Adapter model when used with its appropriate patient population.
•The Airway Adapters are intended for single patient use. They are disposable and shall not be re-used.
Reuse of single patient use Adapters can cause cross infection.
•Airway Adapters shall be disposed of in accordance with local regulations for bio hazardous waste.
