### 5.3. Technological Characteristics
Principle of Operation
{5}------------------------------------------------
Image /page/5/Picture/2 description: The image shows the logo for Masimo Corporation. The logo consists of a red circle with a white checkmark inside, followed by the word "Masimo" in black, bold font. To the right of the word "Masimo" is the text "MASIMO CORP" followed by the address "52 Discovery, Irvine, CA 92618".
The measurement of CO2 in 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 two different optical "color" filters. The wavelength ranges of these filters are chosen such that one filters out wavelengths where carbon dioxide has very strong absorption and the other filters out wavelengths 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.
### Mechanism of Action for Achieving the Intended Effect
The EMMA works by attaching the EMMA Airway adapter between the endotracheal tube and resuscitation bag. The EMMA Airway Adapter once connected to the EMMA monitor becomes the path in which the breathing gas mixture passes. As the breathing gas mixtures passes, the infrared light passes through the light window provided in the adapter. The light window of the adapter aligns on the side with the infrared source and the other side with infrared detector. Based upon the amount of light absorbed when the different filters are in place, a CO2 and respiration rate is displayed on the EMMA monitor.
The EMMA Capnograph snaps in place on top of the EMMA Airway Adapter. The airway adapter may then, for example, be inserted between the endotracheal tube and the resuscitation bag or between the resuscitation bag and the patient mask.
Respiratory gas measurements are, as described in the previous section, obtained by continuously measuring the infrared light absorption through the "XTP Windows" that are transparent to light in the wavelength ranges of interest.
The Airway Adapters are fully sealed, except for the breathing circuit couplings. The breathing circuit couplings conform to existing standards for this type of couplings. The EMMA Sensor Body (reusable portion) does not come in contact with breathing circuit gases or the patient.
### 5.4. Summary of Technological Characteristics of Subject Device Compared to Predicate Device
The subject device incorporates a wireless module and a software modification to enable the radio and support the wireless communication of measurement data from EMMA.
There is no change to the intended use as part of this modification.
### 5.4.1 Similarities and Differences between Predicate and Subject Device
{6}------------------------------------------------
Image /page/6/Picture/2 description: The image shows the logo for Masimo Corporation. The logo consists of a red circle with a white checkmark inside, followed by the word "Masimo" in black, bold letters. To the right of the logo is the text "MASIMO CO" followed by the address "52 Discovery, Irvine, CA 92618".
The subject device, EMMA with wireless capabilities, and the predicate device, have the following key similarities:
- · Both devices have the same intended use;
- · Both devices have the same indicated populations;
- · Both devices have the same measurement technology:
- · Both devices have the same form factor
The subject device, EMMA with wireless capabilities, and the predicate device, have the following key differences:
- · Subject device includes the ability to wirelessly communicate
- · Subject device has a lower storage/transport specification
The purpose of this submission is the addition of the wireless capabilities to the EMMA. As part of the wireless function implementation, a radio module was incorporated into the hardware design and the software was updated to enable the wireless communication. There was no change to the measurement functions or the intended use of the device.
To support the wireless capabilities do not raise different questions of safety and effectiveness, the subject device was evaluated for electromagnetic compatibility testing to the latest IEC 60601-1-2 standard, radio co-existence testing, and cybersecurity risk mitigations.
The testing conducted supported the subject device to be substantially equivalent to the predicate device. Both devices have the same intended use and that the addition of the wireless capabilities does not raise different questions of safety and effectiveness.
