Indications for Use

The Rainbow Resposable Sensors are indicated for the continuous noninvasive monitoring of functional oxygen saturation of arterial hemoglobin (SpO2), pulse rate, methemoglobin saturation (SpMet), and/or total hemoglobin (SpHb). The Rainbow Resposable Sensors are indicated for use with adult and pediatric patients during no motion conditions and for patients who are well or poorly perfused in hospitals, hospital-type facilities, mobile, and home environments.

Device Story

Rainbow Resposable Pulse CO-Oximeter Sensors provide noninvasive optical assessment of tissue oxygenation; inputs include light signals from emitters processed by detectors; device transforms optical signals into physiological parameters (SpO2, pulse rate, SpMet, SpHb). System consists of reusable emitter/detector/cable assembly and single-patient-use tape assembly. Used in hospitals, mobile, and home environments; operated by clinicians or patients. Output displayed on compatible Masimo Rainbow SET monitors; assists healthcare providers in patient status assessment and clinical decision-making. Benefits include continuous monitoring of hemoglobin parameters without invasive sampling.

Clinical Evidence

Clinical studies conducted on adult and pediatric patients. Accuracy metrics reported for SpO2 (±2-3%), pulse rate (±3 bpm), SpMet (±1%), and SpHb (±1 g/dL) under no-motion and low-perfusion conditions. Biocompatibility testing confirmed non-toxic, non-irritating, and non-sensitizing materials. Environmental, electrical, and mechanical testing passed per FDA guidance.

Technological Characteristics

Noninvasive optical tissue oximetry using emitters and detectors. Compatible with Masimo Rainbow SET monitors. Reusable emitter/detector/cable assembly with single-patient-use tape. Materials equivalent to predicate. Electrical, mechanical, and environmental testing performed per 1993 FDA guidance.

Indications for Use

Indicated for continuous noninvasive monitoring of SpO2, pulse rate, SpMet, and SpHb in adult and pediatric patients. Use restricted to no-motion conditions; applicable for well or poorly perfused patients in hospitals, hospital-type facilities, mobile, and home environments.

Regulatory Classification

Identification

An oximeter is a device used to transmit radiation at a known wavelength(s) through blood and to measure the blood oxygen saturation based on the amount of reflected or scattered radiation. It may be used alone or in conjunction with a fiberoptic oximeter catheter.

### Device Description

The Rainbow Resposable Sensors are fully compatible sensors for use with Masimo Rainbow SET and Masimo Rainbow SET compatible pulse CO-Oximeter monitors. They represent a design change to the Masimo Rainbow Adhesive Sensors in the K0801659 filing.

The Rainbow Resposable Sensors have the similar intended use/indications for use and performance specifications as the Rainbow Adhesive Sensors in the K0801659 filing. The main difference is that the entire Rainbow Adhesive Sensor is single-patient use. However for the Rainbow Resposable Sensor, the tape assembly is single-patient use and the emitter/detector/cable assembly is detachable from the tape assembly. This emitter/detector/cable assembly is reusable. Also, the Rainbow Resposable Sensors are not indicated for the measurement of carboxyhemoglobin saturation and motion conditions.

# Predicate Devices

The predicate devices for this filing are the Rainbow Adhesive Pulse CO-Oximetry Sensors (K081659).

# Intended Use/ Indications for Use

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

# 510(k) SUMMARY

## Technology Comparison

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

They are designed, configured, and manufactured for full compatibility with Masimo Rainbow SET and Masimo Rainbow SET compatible pulse CO-Oximeters. The Rainbow Resposable Sensors are constructed of similar materials and components of equivalent specifications as used in the predicate devices, with accuracy that is also equivalent to those of the predicate devices.

## Performance Testing

#### Biocompatibility

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

#### Environmental

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

Clinical studies for the Rainbow Resposable Sensors are similar to those of the Rainbow Adhesive Sensors, resulting in the following sensor specifications for adult and pediatric patients:

| Measurement | Accuracy<br>Range | Accuracy |
|--------------------------------------------------|-------------------|--------------|
| Arterial Oxygen Saturation (SpO2), No Motion | 60-80% | $\pm$ 3% |
| Arterial Oxygen Saturation (SpO2), No Motion | 70-100% | $\pm$ 2% |
| Arterial Oxygen Saturation (SpO2), Low Perfusion | 70-100% | $\pm$ 2% |
| Pulse Rate, No Motion | 25-240 bpm | $\pm$ 3 bpm |
| Pulse Rate, Low Perfusion | 25-240 bpm | $\pm$ 3 bpm |
| Methemoglobin (SpMet), No Motion | 1-15% | $\pm$ 1% |
| Total Hemoglobin Concentration (SpHb), No Motion | 8-17 g/dL | $\pm$ 1 g/dL |
