2. Sample Size Used for the Test Set and Data Provenance:

The document provides specific details for different parameters:

  • SpO2, SpCO, SpMet (Adults): "healthy adult volunteers" were tested.
  • SpO2, SpMet (Neonates): 16 neonatal NICU patients (age 7-135 days, weighing 0.5-4.25 kg). 79 data samples were collected.
  • SpO2 (No Motion): "healthy adult male and female volunteers with light to dark skin pigmentation in induced hypoxia studies."
  • SpO2 (Motion): "healthy adult male and female volunteers with light to dark skin pigmentation in induced hypoxia studies while performing rubbing and tapping motions."
  • SpO2 (Low Perfusion): Bench top testing using a Biotek Index 2 simulator and Masimo's simulator.
  • Pulse Rate: Bench top testing using a Biotek Index 2 simulator.
  • SpHb: "healthy adult male and female volunteers and on surgical patients with light to dark skin pigmentation."

Data Provenance:
The studies appear to be prospective human blood studies on healthy volunteers and surgical patients for SpO2, SpCO, SpMet, and SpHb. Neonatal data was also collected prospectively in a NICU setting. Benchtop testing was used for low perfusion SpO2 and Pulse Rate.

Country of Origin: The document does not explicitly state the country of origin for the human volunteer studies; however, the submission is from Masimo Corporation based in Irvine, CA, USA, and approved by the FDA in the USA, suggesting the studies were likely conducted in the US or under US regulatory standards.

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

The document does not specify the number of experts used or their qualifications for establishing ground truth. The ground truth for the physiological parameters was established using:

  • A laboratory CO-Oximeter for SpO2, SpCO, SpMet, and SpHb.
  • An ECG monitor for SpO2 (no motion and motion studies).
  • A Biotek Index 2 simulator and Masimo's simulator for low perfusion SpO2 and Pulse Rate.

4. Adjudication Method for the Test Set:

The document does not describe any adjudication method involving human experts for the test set. Ground truth was established by reference devices (laboratory CO-Oximeter, ECG monitor) or simulators.

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

No MRMC comparative effectiveness study is mentioned in the provided text. The device is a direct physiological measurement device, not an image interpretation or diagnostic aid that typically involves human readers. Therefore, the concept of human readers improving with AI vs without AI assistance does not directly apply here.

6. Standalone (Algorithm Only) Performance Study:

Yes, the accuracy statements are for the device's standalone performance (algorithm only without human-in-the-loop performance). The accuracies are reported as deviations from concurrently measured reference values (e.g., laboratory CO-Oximeter, ECG monitor, or simulators). For example:

  • "SpO2, SpCO and SpMet accuracy was determined by testing on healthy adult volunteers... against a laboratory CO-Oximeter."
  • "The Masimo sensors have been validated for no motion accuracy... against a laboratory CO-Oximeter and ECG monitor."

7. Type of Ground Truth Used:

The ground truth used for the accuracy studies consists of:

  • Reference device measurements: A laboratory CO-Oximeter and an ECG monitor.
  • Simulator data: Biotek Index 2 simulator and Masimo's simulator for specific conditions (low perfusion SpO2 and pulse rate).

8. Sample Size for the Training Set:

The document does not provide information regarding the sample size for any training sets. Given the nature of a pulse CO-Oximeter which uses established physiological principles and signal processing, it's possible that the "training" (development and refinement) of the algorithms was not conducted in the same manner as for AI/machine learning algorithms that typically require large, distinct training datasets. It likely involved extensive engineering, signal processing, and iterative testing rather than a formalized "training set" in the context of deep learning.

9. How the Ground Truth for the Training Set Was Established:

As no specific training set is described, there is no information on how ground truth for such a set would have been established. Any internal development and testing would have likely relied on similar reference methods as described for the performance studies.

Intended Use/Indications for Use

The Masimo Rainbow SET® Rad 87 Pulse CO-Oximeter and accessories are indicated for the continuous noninvasive monitoring of functional oxygen saturation of arterial hemoglobin (SpO₂), pulse rate, carboxyhemoglobin saturation (SpCO), methemoglobin saturation (SpMet), total hemoglobin concentration (SpHb), and/or respiratory rate (RR). The Masimo Rainbow SET® Rad 87 Pulse CO-

{1}------------------------------------------------

Oximeter and accessories are indicated for use with adult, pediatric, and neonatal patients during both no motion and motion conditions, and for patients who are well or poorly perfused in hospital-type facilities, mobile, and home environments.

Principles of Operation

SpO2 and Pulse Rate

Pulse oximetry is governed by the principles that oxyhemoglobin (oxygenated blood), deoxyhemoglobin (non-oxygenated blood), carboxyhemoglobin (blood with carbon monoxide content), and methemoglobin (blood with oxidized hemoglobin content) species differ in their absorption of visible and infrared light. The amount of arterial blood in tissue changes with the pulse (photoplethysography). Therefore the amount of light, absorbed by the varying quantities of arterial blood, changes accordingly.

SpCO. SpMet, and SpHb General Description

The Rad-87 include the Masimo Rainbow SET technology for SpCO, SpMet and SpHb measurements, based on the same principles of pulse oximetry. The Masimo Rainbow SET technology uses a multiwavelength sensor to distinguish between oxygenated blood, deoxygenated blood, blood with carbon monoxide, blood with oxidized hemoglobin and blood plasma.

Once the Masimo Rainbow SET technology receives the signal from the sensor, it calculates the patient's functional oxygen saturation (SpO2), fractional concentration of carboxyhemoglobin (SpCO), fractional concentration of methemoglobin (SpMet), total hemoglobin concentration (SpHb) and pulse rate.

Respiratory Rate General Description

The Masimo Rainbow SET technology also provides respiratory rate measurements, based on vibratory signals from respiratory sounds.

Method of Operation

SpO2, SpCO, SpMet, and SpHb

The instrument (Rad 87) is turned on. A sensor is attached to a patient's finger. The other end of the sensor is attached to a patient cable. The other end of the patient cable is connected to the Dual Channel cable or directly to the instrument. The connection of the patient cable to the Dual Channel cable is only needed when pulse CO-oximetry monitoring is concurrent with respiratory rate monitoring.

The instrument will begin continuously displaying the patient's pulse rate and SpO2 value. Depending on the type and/or configuration of the instrument, monitoring information would also include SpCO, SpMet, SpHb, PVI, and/or SpOC. The practitioner can then use the information to help assess the condition of the patient and as an aide in determining if any intervention is required by the practitioner.

Once the practitioner determines the patient no longer requires monitoring, the cable is disconnected from the sensor, the sensor is removed (and disposed of if it is a single use device), and the power to the instrument is turned off.

Respiratory Rate

The instrument (Rad 87) is turned on. A sensor is attached to a patient's neck. The other end of the sensor is connected to a patient cable. The other end of the cable is connected to the Dual Channel cable. The Dual Channel cable is then connected to the instrument.

The instrument will begin continuously display the patient's respiratory rate. The practitioner can then use the information to help assess the condition of the patient and as an aide in determining if any intervention is required by the practitioner. Once the practitioner determines the patient no longer requires monitoring, the patient cable is disconnected from the sensor, the sensor is disposed and the power to the instrument is turned off.
