The description focuses on traditional signal processing algorithms for calculating SmO2 from NIRS spectra and does not mention AI or ML.
No
The device is described as a non-invasive monitor intended to measure and display oxygen saturation, and explicitly states it "should not be used as the sole basis for diagnosis or therapy."
No
Explanation: The "Intended Use / Indications for Use" section explicitly states, "The CareGuide System should not be used as the sole basis for diagnosis or therapy." While it provides monitoring data, it is not intended for stand-alone diagnostic purposes.
No
The device description explicitly details hardware components including a sensor with optical and electronic elements, light sources, a spectroscopic detector, a microprocessor, and a cord with a USB connection.
Based on the provided information, the CareGuide™ Oximeter is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, or tissue) to obtain information for diagnostic or monitoring purposes.
- CareGuide™ Oximeter Function: The CareGuide™ Oximeter uses Near Infrared Spectroscopy (NIRS) to non-invasively measure the hemoglobin oxygen saturation of microvascular blood in skeletal muscle tissue directly on the patient's body. It does not involve the collection or analysis of specimens taken from the body.
Therefore, the CareGuide™ Oximeter falls under the category of a non-invasive medical device used for physiological monitoring, not an In Vitro Diagnostic.
N/A
Intended Use / Indications for Use
The CareGuide™ Oximeter is intended for use as an adjunct, non-invasive monitor of the hemoglobin oxygen saturation of microvascular blood in a region of skeletal muscle tissue beneath the sensor. The sensor may be positioned on pigmented skin. The CareGuide displays the most recent value of SmO2, as well as a graphical trend of previous SmO2 measurements. The CareGuide System should not be used as the sole basis for diagnosis or therapy. Note: The prospective clinical value of data from the CareGuide™ Oximeter has not been demonstrated in disease states.

Device Description
The CareGuide sensor uses Near Infrared Spectroscopy (NIRS) to calculate muscle oxygen saturation (SmO2). The CareGuide Display is an all-in-one touch screen off-the-shelf computer. The display contains the user interface software, the algorithms that calculate SmQ2 from collected spectra, displays the current SmO2 result and trends previous results. The CareGuide reusable sensor contains the optical and electronic elements necessary to collect spectra from skin, fat and muscle. The sensor has a 3m long cord with a USB connection to the CareGuide display. The sensor contains 3 major components: (1) light sources to illuminate the skin; (2) a spectroscopic detector to analyze the reflected spectra back from the subject and (3) a microprocessor to control the optical components. The CareGuide Ray is a disposable sleeve which isolates the sensor optical elements from the patient's skin.

Summary of Performance Studies
The accuracy of the CareGuide Oximeter against the gold reference standard of a laboratory co-oximeter was demonstrated in an isolated perfused animal limb GLP study. The ability of the CareGuide Oximeter to measure tissue oxygen saturation in subjects with different skin color (pigmentation) has been demonstrated in the clinical environment.

The CareGuide Oximeter is substantially equivalent to the predicates by intended use and design.
- . The principle of operation of the CareGuide Oximeter is identical to that of the predicate devices. They all use NIR Spectroscopy to measure tissue oxygen saturation.
- . The CareGuide Oximeter is identical to the predicates in components. All devices have a Monitor with a Sensor.
- . The CareGuide Oximeter has the same underlying LED light source as the predicates. with the similar ranges of wavelength (700-900 nm between the three devices).
- The CareGuide Oximeter and the predicates all display output as a numeric trend. .
- The Intended Use is identical to the predicates. They are all intended for use as . oximeters, to measure tissue oxygen saturation.
Further, the CareGuide Oximeter has multiple number of wavelengths like the T-Stat predicate Oximeter
Summary of Safety and Effectiveness Data
Testing demonstrates that the CareGuide Oximeter is a safe and effective oximeter meeting all relevant consensus and FDA recognized standards. The test results in this submission demonstrate that the CareGuide Oximeter meets the expected performance requirements for an Oximeter, and is therefore equivalent to the predicates relative to safety and mechanical properties. The accuracy of the CareGuide Oximeter against the gold reference standard of a

laboratory co-oximeter was demonstrated in an isolated perfused animal limb GLP study. The ability of the CareGuide Oximeter to measure tissue oxygen saturation in subjects with different skin color (pigmentation) has been demonstrated in the clinical environment.
Conclusion
The CareGuide Oximeter is equivalent to predicate devices in terms of technology (NIR Spectroscopy) and intended use. The CareGuide Oximeter, with its multiple source configuration to overcome the effect of skin pigmentation, does not raise new questions of safety or effectiveness, as compared to the predicates. Therefore, the CareGuide Oximeter is substantially equivalent to the predicate devices.
