The Rainbow Adhesive Sensors are indicated for the continuous nonitoring of functional oxygen saturation of arterial hemoglobin (SpO2), pulse rate, carboxyhemoglobin (SpCO), and/or methemoglobin (SpMet) saturation. The Rainbow Achesive Sensors are indicated for use with adult, pediatric, and neonatal patients during both no motion and for patients who are well or poorly perfused in hospital-type facilities, mobile, and home environments.

Device Description

The Rainbow Adhesive Sensors are fully compatible disposable sensor for use with Masimo Rainbow SET compatible pulse CO-Oximeter monitors. They represent a design change to the Masimo Rainbow DCI-DC CO-Oximetry Sensors.

The Rainbow Adhesive Sensors are similar in the predicate devices except for a recessed emitter. The emitter and detector assemblies are connected to the sensors have an adhesive bandage to allow the sensor to be attached to the patient's finger, hand, foot or toe. The same emitters (with 8 wavelengths) are used in Rainbow Adhesive Sensors. Four sizes of Rainbow Adhesive Sensors are available for use with adult, pediatric, infant and neonatal patients. The four sensors are essentially identical except for the emitter and detector spacing and size and orientation of the patient contacting materials in the Rainbow Adhesive Sensors are the same that is used in Masimo's LNCS and LNOP single use sensor lines. The Rainbow Adhesive Sensors are supplied non-sterile for single patient use.

SpO2 (Neonatal): "hospitalized neonatal patients" - The specific sample size is not stated, but the study was prospective (clinical study).
SpCO & SpMet (Adult): "healthy adult volunteers" - The specific sample size is not stated, but the study was prospective (human blood studies).
SpMet (Neonatal): "hospitalized neonatal patients" - The specific sample size is not stated, but the study was prospective (clinical study).

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications:

The document does not provide details on the number or qualifications of experts used to establish ground truth.

4. Adjudication Method for the Test Set:

Not applicable. The ground truth was established through objective laboratory measurements (CO-Oximeter blood samples) rather than expert consensus on subjective interpretations.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study:

A MRMC comparative effectiveness study was not explicitly mentioned or performed. The study focuses on the device's accuracy against a reference standard, not its impact on human readers' performance with or without AI assistance.

6. Standalone Performance (Algorithm only without human-in-the-loop performance):

Yes, the studies described are for standalone performance. The device's accuracy (SpO2, SpCO, SpMet) is measured directly against a reference standard (arterial blood samples analyzed by a CO-Oximeter), without human interpretation of the device's output influencing the ground truth comparison.

510(k) SUMMARY

Technology Comparison

The Rainbow Adhesive Sensors are substantially equivalent in intended use, design, principles of operation, and performance to predicate sensors and operate on identical principles of non-invasive optical assessment of tissue oxygenation using emitters and detectors.

The Rainbow Adhesive Sensors are designed, and manufactured for full compatibility with Masimo Rainbow SET and Masimo Rainbow SET compatible pulse CO-Oximeters. The Rainbow Adhesive Sensors are constructed of similar materials and components of equivalent specifications as used in the predicate devices.

The accuracy of the Rainbow Adhesive Sensors are equivalent to those of the predicate devices.

Performance Testing

Biocompatibility

Test results of all the patient contacting materials used in the Rainbow Adhesive Sensors demonstrated that the materials were non-toxic, non-irritating, and non sensitizing.

Environmental Testing

Applicable environmental testing per the Reviewers Guidance for Premarket Submissions - November 1993, i.e. electrical, mechanical and environmental were performed and all tests passed

Clinical Testing

Clinical studies were performed using Rainbow SET technology with Rainbow Adhesive Sensors on healthy adult volunteer subjects during motion conditions who were subjected to a progressive induced hypoxia and measuring the arterial hemoglobin saturation value with the instruments against the arterial hemoglobin oxygen determined from arterial blood samples with a CO-Oximeter. Clinical testing of the Rainbow Adhesive sensors resulted in an accuracy of less than 2% SpO2 Agys in the range of 70%-100% SaO2 and less than 3% SpO2 Apps in the range of 60%-80% SaO2 for adults, pediatrics and infants.

Additional clinical studies were performed using Masimo Rainbow SET technology with Rainbow Adhesive Sensors on hospitalized neonatal patients resulted in an accuracy of less than 3% SpO2 Aross in the range of 70%-100% SaO2.

The Masimo Rainbow SET technology with Rainbow Adhesive Sensors have been validated in human blood studies on healthy adult volunteers against a laboratory CO-Oximeter from 1-40% for carboxyhemoglobin and 1-15% for methemoglobin. Clinincal testing of the Rainbow Adhesive sensors resulted in an accuracy of less than 3% SpCO Agos in the range of 1%-40% SaCO and an accuracy of less than 1% SpMet ABMS in the range of 1%-15% SaMet.
