The document describes the use of "two separate algorithms" to calculate parameters from spectroscopic data, but there is no mention of AI, ML, or related terms like neural networks or deep learning. The description of the algorithms is limited to their function in converting reflected light to an absorbance spectrum and then calculating the parameters.
No.
The device is a non-invasive monitor that provides data (SmO2 and pHm) but explicitly states it "should not be used as the sole basis for diagnosis or therapy."
No
The document states, "The Multi-Parameter Mobile CareGuide 4100 Oximeter should not be used as the sole basis for diagnosis or therapy." This indicates it's an adjunct monitor, not a primary diagnostic tool.
No
The device description clearly details a physical sensor with light sources, a spectroscopic detector, and a microprocessor that performs data collection and analysis. While it interfaces with a display device via software, the core medical device functionality resides in the hardware sensor.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs analyze samples taken from the body (in vitro), such as blood, urine, or tissue. This device is a non-invasive optical sensor that measures parameters in the body (in vivo) by shining light through the skin and analyzing the reflected light.
- The intended use and device description clearly state it measures parameters of microvascular blood in a region of skeletal muscle tissue beneath the sensor. This is a direct measurement within the body, not an analysis of a sample taken from the body.
Therefore, the Multi-Parameter Mobile CareGuide™ 4100 Oximeter is a non-invasive medical device used for monitoring physiological parameters in vivo.

Intended Use / Indications for Use
The Multi-Parameter Mobile CareGuide™ 4100 Oximeter is intended for use as an adjunct, non-invasive monitor of the hemoglobin oxygen saturation and pH of microvascular blood in a region of skeletal muscle tissue beneath the sensor. The sensor may be positioned on pigmented skin. The Multi-Parameter Mobile CareGuide 4100 Oximeter is intended to allow for display of SmO2 and pHm data on a third party or Reflectance supplied device, which would interface with the Multi-Parameter Mobile CareGuide 4100 Oximeter via a powered USB connection. The Multi-Parameter Mobile CareGuide 4100 Oximeter is intended for prescriptive use (Rx only) by a trained healthcare professional inside and outside a hospital. The Multi-Parameter Mobile CareGuide 4100 Oximeter provides output of the most recent values of SmO2 and pHm in a trend, as well as operational device information. The Multi-Parameter Mobile CareGuide 4100 Oximeter should not be used as the sole basis for diagnosis or therapy. Note: The prospective clinical value of data from the Multi-Parameter Mobile CareGuide 4100 Oximeter has not been demonstrated in disease states.

Device Description
The Multi-Parameter Mobile CareGuide 4100 is a noninvasive optical sensor that determines two separate medical parameters and reports them out for display to the user in real-time. Light sources in the sensor illuminate the skin with near infrared (NIR) light passes through the skin and fat with only some loss to be primarily absorbed by small blood vessels in the muscle tissue. Light which is not absorbed is scattered back and analyzed by the spectroscopic detector, also contained in the sensor. The microprocessor in the sensor converts the reflected light to an absorbance spectrum which is then analyzed by two separate algorithms, also stored in the sensor's microprocessor. The two algorithms calculate muscle oxygen saturation (Sm22), and muscle pH (pHm).
The sensor is attached to the patient using the CareGuide Disposable. One Disposable is used per patient, but the CareGuide Sensor is reusable. To use, the adhesive liner is removed from the Disposable and, with the sensor clipped into the Disposable, is adhered to the patient's skin over either the deltoid, calf or thigh muscle.
When the sensor is first placed on the patient, software checks to make sure the LEDs are functioning properly and then the sensor automatically performs an optimization routine which sets up the spectral data collection parameters for the individual patient. Once conditions are established the sensor begins collecting spectra and reporting parameter values.
The Multi-Parameter Mobile CareGuide 4100 measures and provides for output of SmO2 and pHm data. The Multi-Parameter Mobile CareGuide 4100 communicates with either a 3rd party display or monitoring device, or RMI-supplied tablet, which is compliant with the Mobile CareGuide communications protocol. Sm02 and pHm values suitable for display and trending are sent via the Mobile CareGuide communications protocol to the display device as well as error information and device states.
