Indications for Use
The Masimo Rainbow SET® RadCheck Pulse CO-Oximeter and Accessories are indicated for noninvasive spot checking of functional saturation of arterial hemoglobin (SpO2), pulse rate, and total hemoglobin (SpHb). The Masimo Rainbow SET® RadCheck Pulse CO-Oximeter and Accessories are indicated for use, by trained personnel, with adult and pediatic patients during both no motion and motion conditions, and for patients who are well or poorly perfused in clinical and non-clinical settings.
Device Story
RadCheck is a portable, microprocessor-controlled pulse CO-oximeter for spot-checking vital signs. It utilizes 12-wavelength optical sensor technology to measure arterial oxygen saturation (SpO2), pulse rate, and total hemoglobin (SpHb). Input signals from the sensor are processed to output SpO2, pulse rate, SpHb, Perfusion Index (PI), and Total Arterial Oxygen Content (SpOC). The device is operated by trained personnel in clinical or non-clinical settings. Output is displayed on the device screen, allowing clinicians to assess patient status immediately. The device provides a noninvasive alternative to laboratory blood analysis, facilitating rapid clinical decision-making regarding oxygenation and hemoglobin levels.
Clinical Evidence
Clinical validation performed on healthy adult volunteers and surgical patients with varying skin pigmentation. Accuracy for SpO2 and pulse rate validated against laboratory CO-oximeter and ECG monitors under no-motion, motion, and low-perfusion conditions. SpHb accuracy validated in the 8-17 g/dl range. Bench testing conducted using Biotek Index 2 and Masimo simulators. Results demonstrate performance within specified tolerances (±1 SD).
Technological Characteristics
Microprocessor-controlled; 12-wavelength optical sensing; Polycarbonate/ABS blend housing; internally powered by non-rechargeable batteries; Type BF-applied part; IPX1 ingress protection. Connectivity via Masimo Rainbow sensors. Complies with EN 60601-1-2 (EMC) and IEC/UL 60601-1 (Electrical Safety).
Indications for Use
Indicated for noninvasive spot checking of SpO2, pulse rate, and total hemoglobin (SpHb) in adult and pediatric patients. Suitable for use in clinical and non-clinical settings by trained personnel under motion/no-motion conditions and varying perfusion states.
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 Masimo Rainbow SET® RadCheck Pulse CO-Oximeter and Accessories (RadCheck) have modified intended use/indications for use in comparison to the Rad 57t Pulse CO-Oximeters and Accessories (Rad 57t) in the K080238 filing. The main difference is that the RadCheck in this filing is for spot checking, whereas the Rad 57t in K0808238 is for continuous monitoring. The keypad membrane and the software of the RadCheck also differ from the Rad 57t.
The RadCheck in this filing is similar in construction to the Rad 57t in the K0808238 filing, including the 12-wavelength technology for the measurement of total hemoglobin. The performance of the Radcheck is similar to the Rad 57t. Similar to the Rad 57t, the RadCheck provides noninvasive monitoring of arterial oxygen saturation (%SpO2), pulse rate, and total hemoglobin concentration (g/d) SpHb). Other information displayed by the RadCheck include: Low Signal IQ (Low SIQ), Perfusion Index (PI), Total Arterial Oxygen Content (SpOC), battery life, and sensor status.

## Footnotes
- SpO2 accuracy was determined by testing on healthy adult volunteers in the range of 1 60-100% SpO2 against a laboratory CO-Oximeter.
- 2 The Masimo sensors have been validated for no motion accuracy in human blood studies on healthy adult male and female volunteers with light to dark skin pigmentation in induced hypoxia studies in the range of 70-100% SpO2 against a laboratory CO-Oximeter and ECG monitor. This variation equals plus or minus one standard deviation. Plus or minus one standard deviation encompasses 68% of the population weight.
- ന The Masimo sensors have been validated for motion accuracy in human blood studies on healthy adult male and female volunteers with light to dark skin pigmentation in induced hypoxia studies while performing rubbing and tapping motions, at 2 to 4 Hz at an amplitude of 1 to 2 cm and a non-repetitive motion between 1 to 5 Hz at an amplitude of 2 to 3 cm in induced hypoxia studies in the range of 70-100% SpO2 against a laboratory CO-oximeter and ECG monitor. This variation equals plus or minus one standard deviation which encompasses 68% of the population.
- 4 The Masimo SET Technology has been validated for low perfusion accuracy in bench top testing against a Biotek Index 2 simulator and Masimo's simulator with signal strengths of greater than 0.02% and transmission of greater than 5% for saturations ranging from 70 to 100%. This variation equals plus or minus one standard deviation which encompasses 68% of the population.
{4}------------------------------------------------
- The Masimo sensors have been validated for pulse rate accuracy for the range of 5 25-240 bpm in bench top testing against a Biotek Index 2 simulator. This variation equals plus or minus one standard deviation which encompasses 68% of the population.
- 6 If the batteries are to be stored for extended periods of time, it is recommended that they be stored between -20 to +30°C, and at a relative humidity less than 85%. If stored for a prolonged period at environmental conditions beyond these limits, overall battery capacity may be diminished, and lifetime of the batteries may be shortened.
