No
The document explicitly states "Mentions AI, DNN, or ML: Not Found" and describes the technology as "Masimo SET pulse oximetry and Respiration Rate from the Plethysmograph," which are established signal processing techniques, not AI/ML.

No
The device is intended for monitoring physiological parameters (SpO2, PR, RRp), not for delivering therapy or direct treatment.

No

Monitoring SpO2, Pulse Rate, and Respiration Rate are measurements of physiological parameters, not diagnostic interpretations of conditions or diseases.

No

The device description explicitly states that the Rad-G is a "handheld pulse oximeter" and is "provided with an internal battery and a connection to an external power supply," indicating it is a hardware device.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. These tests are performed outside the body (in vitro).
  • Device Function: The Rad-G Pulse Oximeter is a non-invasive device that measures physiological parameters (SpO2, Pulse Rate, Respiration Rate) directly from the patient's body (specifically, the finger) using light and a sensor. It does not analyze samples taken from the body.

Therefore, the Rad-G Pulse Oximeter falls under the category of a non-invasive physiological monitoring device, not an In Vitro Diagnostic.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Biocompatibility Testing: Not considered necessary for the Masimo Rad-G itself as it does not make direct patient contact. Accessories (Rad-G reusable and Rad-G YI sensors) were evaluated for biocompatibility, with patient contacting parts being the same as previously cleared RD SET versions (K193242).

Electromagnetic Compatibility, Electrical Safety, Environmental, Mechanical and Cleaning: Testing was conducted to support the Masimo Rad-G and Accessories meet its specification and its substantial equivalence. Cleaning validation was not conducted as the device is not intended for direct patient contact.

Software Verification and Validation Testing: Conducted and documentation provided per FDA's Guidance, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices", dated May 11, 2005. The software was considered a "moderate" level of concern. Test results supported substantial equivalence.

Human Factors Usability Testing: Previous human factors testing on the predicate device was considered sufficient to support acceptability, in accordance with the FDA Guidance, "Applying Human Factors and Usability Engineering to Optimize Medical Device Design", dated February 3, 2016.

Non-clinical Performance Testing: Bench testing performed to ensure successful integration of monitoring technologies and electrical sensor connection, as the subject device uses the same monitoring technologies as the predicate (K193242). Test results supported substantial equivalence.

Clinical Testing: Not deemed necessary as the subject device utilizes the same monitoring technologies as the predicate (K193242).

The Rad-G Pulse Oximeter and Accessories are indicated for noninvasive spot-checking or continuous monitoring of functional oxygen saturation of arterial hemoglobin (SpO2) and Pulse Rate (PR) of adult, pediatric, infant, and neonate patients during both no motion conditions, and for patients who are well or poorly perfused in hospitals, hospital-type facilities, transport, and home environments.

3. Technological Characteristics

Principle of Operation

The Rad-G Pulse Oximeter and Accessories utilize the same principles of operation for functional oxygen saturation of arterial hemoglobin (SpO2), Pulse Rate (PR), and Respiration Rate from the Pleth (RRp) as the Radical-7 previously FDA 510(k) cleared under K193242. The principles of operation of pulse oximetry is based upon the fundamental principle that hemoglobin bound to oxygen (oxyhemoglobin) and hemoglobin unbound to oxygen (deoxyhemoglobin) vary in the absorption of different wavelengths of the light and the absorptions can be used to estimate SpO2 and PR. RRp relies on the principle that the cyclic variations in plethysmograph can be used to establish a respiration rate measurement.

Mechanism of Action for Achieving the Intended Effect

The Rad-G Pulse Oximeter and Accessories, the same as the predicate, provide the intended effect similar to the previously cleared Radical-7 in that it utilizes an optical sensor that is applied to the patient's finger to pass light through the tissue to the photodetector that detects the signal variation resulting from differences in the absorption of light. The signals are then passed to the Rad-G Pulse Oximeter where they are processed to provide the SpO2, PR, and RRp values that are then displayed.

4. Summary of Technological Characteristics of Subject Device Compared to Predicate Device

Similarities and Differences between Predicate and Subject Device

The subject device, Masimo Rad-G and Accessories, and the predicate device, Masimo Radical-7 and Accessories (K193242), have the following key similarities:

  • Both devices utilize the same technology to continuously monitor Masimo SET Technology and support Respiration rate through Plethysmograph (RRp)
  • . Both devices have the same performance specifications for the parameters
  • . Both devices utilize a touch screen user interface with a similar graphical user interface layout
  • . Both devices are provide with internal rechargeable batteries so that they can operate on internal battery or AC power

Image /page/6/Picture/1 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 CORPORATION" followed by the address "52 Discovery, Irvine, CA 92618".

The subject device, Masimo Rad-G and Accessories, and the predicate device, Masimo Radical-7 and Accessories (K193242), have the following key differences:

  • The subject device includes an indication for spot-checking
  • . The subject device only provides a smaller subset of monitoring parameters
  • . The subject device has different environmental specifications, including ingress protection rating
  • . The subject device has a different physical appearance (e.g. enclosure size and shape)
  • . The subject device does not require a docking station in order to be powered by AC power

See Table 4.1 for the comparison between the subject device and predicate device.

As compared to the Radical-7, the main modifications are in the added spot-checking indication, physical appearance, ability to connect directly to as external AC/DC power supply versus a docking station, environmental specifications, and the software which was modified to be compatible with the Rad-G hardware and support the simplification of the user interface to limit the number of displayed parameters, as compared to the Radical-7.

The substantial equivalence of the Rad-G to the predicate device. Radical-7, was supported by the same intended use and technological characteristics in providing SpO2, PR, and RRp. To support the indication for spot-checking do not raise different questions of safety and effectiveness, the MightySat (K181956), which is cleared for spot-checking and has similar technological characteristic, was included as a reference predicate. The non-clinical testing supported the other differences related to the software, environmental specifications, AC power source, and physical characteristics do not raise new questions of safety and effectiveness. The testing was found to support the substantial equivalence of the subject device to the predicate.

5. Performance Data

Biocompatibility Testing:

The Masimo Rad-G is not intended to make direct patient contact. Therefore, biocompatibility testing was not considered necessary.

The accessories which are intended to make contact with the patient were evaluated for biocompatibility. The accessories to be used with the Rad-G are the same as those for the predicate, Radical-7 (K193242), with the exception of the Rad-G reusable and Rad-G YI sensors.

For the Rad-G reusable and Rad-G YI sensors, the patient contacting parts are the same as the previously cleared RD SET version under K193242. The difference between the Rad-G reusable DCI and Rad-G YI sensor is in the device connector which makes them compatible to the Rad-G device.

Electromagnetic Compatibility, Electrical Safety, Environmental, Mechanical and Cleaning

Electromagnetic Compatibility, Electrical Safety, Environmental, and Mechanical testing was conducted to support the Masimo Rad-G and Accessories meet its specification and its substantial equivalence. As the Rad-G is not intended to make direct patient contact, cleaning validation was not conducted.

Software Verification and Validation Testing

Software verification and validation testing were conducted and the documentation is provided as recommended by FDA's Guidance, Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices, dated May 11, 2005. The software for this device was considered as a "moderate" level of concern, as defined by the FDA guidance, Guidance for Industry and FDA Staff -Pulse Oximeters - Premarket Notifications [510(k)s], dated March 3, 2013, which identifies that a failure or latent flaw in the software could directly result in minor to moderate injury to the patient. The test results were found to support the substantial equivalence of the subject device.

Human Factors Usability Testing

As the subject device and the predicate provide similar user interface, the previous human factors testing conducted on the predicate device was considered to support the acceptability of the human factors and usability risks of the subject device. The acceptability of the human factors and usability risks took into account the FDA Guidance, Applying Human Factors and Usability Engineering to Optimize Medical Device Design, dated February 3, 2016.

Non-clinical Performance Testing

As the subject device utilizes the same monitoring technologies as the predicate (K193242), non-clinical performance bench testing was performed to ensure the successful integration of the monitoring technologies and electrical sensor connection. The test results were found to support the substantial equivalence of the subject device.

12

Image /page/12/Picture/1 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, sans-serif font. To the right of the logo is the text "MASIMO CORPORATION" in a smaller, gray font, followed by the address "52 Discovery, Irvine, CA 92618" also in gray.

Clinical Testing

As the subject device utilizes the same monitoring technologies as the predicate (K193242), additional clinical testing was not deemed necessary to support the substantial equivalence.

6. Conclusion

The subject device and the predicate device have the same intended use, and the difference in technological features do not raise different questions of safety and effectiveness. The data provided supports the substantial equivalence of the Masimo Rad-G and Accessories to the proposed predicate device.
