(Specification Table, SpHb Accuracy)- Note: SpHb accuracy not validated with motion or low perfusion.

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

  • SpO2, SpCO, SpMet (Adults): "Healthy adult volunteers" for SpO2 (60-100%), SpCO (0-40%), and SpMet (0-15%). The exact number of volunteers is not specified, but it's stated that "This variation equals plus or minus one standard deviation. Plus or minus one standard deviation encompasses 68% of the population weight." (Footnote 2). The data provenance is described as "human blood studies" and "induced hypoxia studies," implying prospective data collection in a controlled setting (likely the US, given the submission location).
  • SpO2, SpMet (Neonates): "16 neonatal NICU patients ranging in age from 7-135 days old and weighing between 0.5-4.25 kg." "Seventy-nine (79) data samples were collected." This appears to be prospective clinical data. The country of origin is not specified but is likely in the US.
  • SpO2 (Motion Conditions): "healthy adult male and female volunteers with light to dark skin pigmentation in induced hypoxia studies while performing rubbing and tapping motions." The specific number of volunteers is not provided. Data provenance is prospective human blood studies in a controlled environment.
  • SpO2 (Low Perfusion): "Bench top testing against a Biotek Index 2 simulator and Masimo's simulator." This is simulated data, not human patient data.
  • Pulse Rate: "Bench top testing against a Biotek Index 2 simulator." This is simulated data, not human patient data.
  • SpHb (Adults/Pediatrics): "healthy adult male and female volunteers and on surgical patients with light to dark skin pigmentation." The specific number of volunteers/patients is not provided. Data provenance is described as human clinical studies.

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

The ground truth was established by a "laboratory CO-Oximeter" for SpO2, SpCO, SpMet, and SpHb, and an "ECG monitor" for SpO2 (in conjunction with the laboratory CO-Oximeter) and a "Biotek Index 2 simulator" for pulse rate and low perfusion SpO2.

No human experts were explicitly stated to establish the ground truth for the measurements; rather, validated reference instruments were used. Therefore, the concept of "number of experts" and "qualifications of experts" as typically applied to image annotation (e.g., radiologists) is not directly applicable here. The accuracy of the reference instruments serves as the ground truth.


4. Adjudication Method for the Test Set

Not applicable. The ground truth was established by reference instruments (laboratory CO-Oximeter, ECG monitor, Biotek Index 2 simulator), not by human adjudication of observations.


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

No. The description focuses on the standalone performance of the device against reference standards, not on how human readers improve with or without AI assistance. This device is a measurement instrument, not an AI diagnostic tool that assists human readers.


6. Standalone (Algorithm-Only) Performance Study

Yes, this entire submission is primarily a standalone performance study. The reported accuracies (e.g., ±2%, ±3%, ±1 g/dl) are for the Masimo devices running their internal algorithms, comparing their output directly to established reference methods (laboratory CO-Oximeter, ECG, simulators). There is no human-in-the-loop component mentioned in these performance evaluations.


7. Type of Ground Truth Used

The type of ground truth used is reference standard measurements:

  • Laboratory CO-Oximeter: For SpO2, SpCO, SpMet, and SpHb.
  • ECG monitor: For SpO2 (used in conjunction with the CO-Oximeter).
  • Biotek Index 2 simulator and Masimo's simulator: For SpO2 (low perfusion) and Pulse Rate.

8. Sample Size for the Training Set

The document does not explicitly mention a "training set" in the context of machine learning or AI algorithms. The device utilizes "multi-wavelength calibration equations" (Section 5, Page 3), which would have been developed using a dataset, but the size of this dataset is not specified. The studies described appear to be validation (test set) studies for the final calibrated device.


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

As with point 8, the document does not detail how a "training set" ground truth was established. The device relies on "multi-wavelength calibration equations." It can be inferred that these equations were developed and calibrated using a similar methodology to the validation studies (i.e., comparing non-invasive readings to invasive or gold-standard laboratory CO-oximetry measurements across a range of physiological states and patient types). However, the specifics of this development process, including sample size or ground truth establishment for that specific phase, are not provided.

Principles of Operation

SpO2 General Description

Pulse oximetry is a continuous and non-invasive method of measuring the level of arterial oxygen saturation in blood. The measurement is taken by placing a sensor on a patient, usually on the fingertip for adults, and the hand or foot for neonates. The sensor connects directly to the pulse oximetry instrument or with a patient cable. The sensor collects signal data from the patient and sends it to the instrument displays the calculated data in tw

ways: 1) as a percent value for arterial oxygen saturation (SpO2), and 2) as a pulse rate (PR). Figure 1 shows the general monitoring setup ..

SpCO, SpMet, and SpHb General Description

Instruments containing Masimo Rainbow SET technology also offer a continuous and non-invasive method of measuring the levels of carboxyhemoglobin concentration (SpCO), methemoglobin concentration (SpMet) and total hemoglobin in blood (SpHb). It relies on the same principles of pulse oximetry to make SpCO, SpMet and SpHb measurements. The measurements are taken by placing a sensor on a patient, usually on the fingertip for adults. The sensor connects directly to the instrument or with a patient cable. The sensor collects signal data from the patient and sends it to the instrument. The instrument displays the calculated data as percentage values for the SpCO and the SpMet and as grams/deciliter (g/dL) for SpHb. Instruments containing Masimo Rainbow SET technology are a combined SpO2, SpMet and SpHb monitor with the same setup as that of a pulse oximeter, shown above, and can display percentage or concentration values for SpCO, SpMet and SpHb as well as SpO2 and pulse rate.

Pulse oximetry is governed by the following principles:

  • Oxyhemoglobin (oxygenated blood), deoxyhemoglobin (non-oxygenated blood), carboxyhemoglobin 1. (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 your pulse (photoplethysography). Therefore, the ં મં amount of light absorbed by the varying quantities of arterial blood changes as well.

Instruments containing Masimo Rainbow SET technology use a multi-wavelength sensor to distinguish between oxygenated blood, deoxygenated blood, blood with carbon monoxide, blood with oxidized hemoglobin and blood plasma. Signal data is obtained by passing various visible and infrared lights (LED's, 620 to 1270 mm) through a capillary bed (for example, a fingertip, a hand, a foot) and measuring changes in light absorption during the blood pulsatile cycle (see Figure 3). The photodetector receives the light, converts it into an electronic signal and sends it to the Radical 7/ Rad 87/ Rad-57t for calculation.

Once the instrument containing Rainbow SET technology receives the signal from the sensor, it utilizes Masimo Signal Extraction Technology (SET) to calculate the patient's functional oxygen saturation (SpO2), fractional concentration of carboxyhemoglobin (SpCO), fractional concentration of methemoglobin (SpMet), total hemoglobin concentration (SpHb) and pulse rate (PR). In instruments containing Masimo Rainbow SET technology. multi-wavelength calibration equations are used to estimate the saturation and concentration values.

Method of Operation

The Radical 7, Rad 87, and the Rad 57t have the same method of operation. The instrument is turned on. An oximetry sensor is attached to a patient's finger and one end of a patient cable is connected to the sensor and the other end connected to the instrument.

The monitor 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 CaO2. The practitioner can 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 CO-oximetry sensor is removed (and disposed of if it is a single use device), and the power to the monitor is turned off.

Seventy-nine (79) data samples were collected over a range of 70-100% SaO2 and 0.5-2.5% MetHb with a resultant accuracy of 2.9% SpO2 and 0.9% SpMet.
  • 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.
  • 3 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.
  • 5 The Masimo sensors have been validated for pulse rate accuracy for the range of 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.
  • This represents approximate run time at the lowest indicator brightness and pulse tone turned 6 off using fully charged battery.
  • 7 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.
