| 70-100 ± 3% | ≤ 3% (RMS) | Adults/Pediatrics/Infants/Neonates | Motion | |
| 70-100 ± 2% | ≤ 2% (RMS) | Adults/Pediatrics/Infants/Neonates | Low Perfusion | |
| PR | ||||
| 25-240 ± 3 bpm | ≤ 3 bpm (RMS) | Adults/Pediatrics/Infants/Neonates | No Motion/Low Perfusion | |
| 25-240 ± 5 bpm | ≤ 5 bpm (RMS) | Adults/Pediatrics/Infants/Neonates | Motion | |
| SpCO | 1-40 ± 3% | ≤ 3% (RMS) | Adults/Pediatrics/Infants | |

| RRa | 4-70 + 1 breath per minute | ≤ 1 breath per minute (RMS) | Adults |
Note: The document states "The studies resulted in accuracies (rms) of equal to or less than the respective accuracies as stated above in the Radical 7 specifications." This implies that the reported device performance met or exceeded the "Acceptance Criteria" values listed in the specification table.
2. Sample Size Used for the Test Set and Data Provenance
- SpO2, SpCO, SpMet (Adult/Pediatric/Infant): Healthy adult volunteers. The exact number of volunteers is not specified, but the range of SpO2 (60-100%), SpCO (0-40%), and SpMet (0-15%) was tested.
- SpHb (Adult/Pediatric): Healthy adult volunteers and surgical patients with light to dark skin pigmentation. The exact number of patients is not specified, but the range of SpHb (8-17 g/dl) was tested.
- SpO2 and SpMet (Neonatal): 16 neonatal NICU patients.
- Age range: 7-135 days old
- Weight range: 0.5-4.25 kg
- Number of data samples: 79 samples collected over a range of 70-100% SaO2 and 0.5-2.5% MetHb.
- RRa: Adults. The exact number of subjects is not specified.
Data Provenance: The studies appear to be prospective clinical studies conducted with human subjects. The country of origin for the data is not explicitly stated.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
This type of device (pulse CO-Oximeter) uses a laboratory CO-Oximeter as the ground truth reference, not human experts. Therefore, information regarding "number of experts" and "qualifications of those experts" is not applicable in this context.
4. Adjudication Method for the Test Set
Not applicable. The ground truth is established by a laboratory CO-Oximeter, which provides objective measurements, removing the need for human adjudication of results.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, If So, What Was the Effect Size of How Much Human Readers Improve with AI vs Without AI Assistance
No, an MRMC comparative effectiveness study was not done. This device is a measurement device and its performance is evaluated against a golden standard reference (laboratory CO-Oximeter), not against human interpretation or a human-AI collaborative workflow.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
Yes, the studies described are standalone performance evaluations. The device's measurements (SpO2, PR, SpCO, SpMet, SpHb, RRa) are directly compared against the ground truth established by a laboratory CO-Oximeter or other appropriate reference standards, without human interpretation in the loop impacting the accuracy determination.
7. The Type of Ground Truth Used
The primary ground truth used is measurements from a laboratory CO-Oximeter.
- For SpO2, SpCO, SpMet, and SpHb, the device was tested "against a laboratory CO-Oximeter."
- For RRa, the specific ground truth method is not detailed beyond "based on vibratory signals from respiratory sounds," but it would involve a highly accurate reference for respiratory rate.
8. The Sample Size for the Training Set
The document does not provide details on a separate "training set" or its sample size. The description focuses on clinical studies performed for performance validation, which typically serve as the test set for regulatory submission. It's possible that internal development and calibration involved various datasets, but these are not explicitly detailed as a separate "training set" in this 510(k) summary.
9. How the Ground Truth for the Training Set Was Established
As no explicit "training set" details are provided in this summary, the method for establishing its ground truth is also not mentioned. However, it can be inferred that any internal development or calibration data would likely have been established using similar reference standards (e.g., laboratory CO-Oximeters) as used for the validation studies.

Intended Use/Indications for Use
The Masimo Radical 7 Pulse CO-Oximeter and accessories are indicated for the continuous non-invasive 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 (RRa). The Masino Radical 7 Pulse CO-Oximeter and accessories are indicated for use with adult, pediatric, and neonatal patients during both no 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 blood contents differ in their absorption of red and infrared light and blood pulsation.
SpCO, SpMet, and SpHb: The Radical 7 includes the Masimo Rainbow SET technology board, which calculates functional oxygen saturation (SpO₂), fractional concentration of carboxyhemoglobin (SpCO), fractional concentration of methemoglobin (SpMet), total hemoglobin concentration (SpHb) and pulse rate.
Respiratory or Respiration Rate (RRa) General Description: The Masimo Rainbow SET technology also provides respiratory or respiration rate measurements, based on vibratory signals from respiratory sounds.

Clinical Summary
Clinical Studies: SpO2, SpCO and SpMet accuracy was determined by testing healthy adult volunteers in the range of 60-100% SpO2, 0-40% SpCO, and 0-15% SpMet against a laboratory CO-Oximeter. SpHb accuracy has been validated on healthy adult volunteers and on surgical patients with light to dark skin pigmentation in the range of 8-17 g/dl SpHb against a laboratory CO-oximeter. The variation in these studies equals one standard deviation which encompasses 68% of the population. SpO₂ and SpMet accuracy was determined on 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 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.
Clinical Results: No device-related adverse events. The clinical studies were performed in accordance with ISO 9919:2005. The studies resulted in accuracies (rms) of equal to or less than the respective accuracies as stated above in the Radical 7 specifications.
Non-Clinical Summary
The Radical 7 complies with the voluntary standards as detailed in this submission. Laboratory testing for rne radical 7 compleo with the voluntary overify that the Radical 7 met all design specifications and was circularitially equivalent to the predicate device. This device was not tested for biocompatibility because like the predicate device, it does not contain any patient contacting materials.
