Device Description

The subject device, Masimo Rad-97 System and Accessories (Rad-97 product family), features a touchscreen display that continuously displays numeric values for the measured monitoring parameters. The Rad-97 product family can be operated on AC power or internal rechargeable battery.

The subject device (Rad-97 product family) is substantially the same as the predicate (Rad-97 product family) cleared under K180046, and has the same indications for use. The Rad-97 comprises of the same measurement technologies as cleared in the predicate, which includes the Masimo rainbow SET technology, capnography technology, and noninvasive blood pressure (NIBP) technology. These technologies enable the Rad-97 product family to provide noninvasive monitoring of functional oxygen saturation of arterial hemoglobin (SpO2), pulse rate (PR), Perfusion Index (Pi), Pleth Variability Index (PVi), carboxyhemoglobin (SpCO), methemoglobin (SpMet), total hemoglobin (SpHb), oxygen content (SpOC), acoustic respiration rate (RRa), and/or optional capnography parameters or optional noninvasive blood pressure (NIBP) parameters.

The subject of this submission is the update to the SpO2 performance specification for the RD SET Disposable sensors for the neonate population to match that of the cleared 1.5% Arms for adults (K180046).

AI/ML Overview

The document describes a 510(k) premarket notification for the "Masimo Rad-97 and Accessories" with a focus on an update to the SpO2 performance specification for the neonate population. The primary goal of the submission is to demonstrate that the device, specifically the RD SET Disposable sensors, maintains its performance for neonates consistent with previously cleared specifications for adults.

Here's a breakdown of the acceptance criteria and the study that proves the device meets them:

1. A table of acceptance criteria and the reported device performance

The document does not explicitly state "acceptance criteria" in a table format with a pass/fail. Instead, it refers to the "SpO2 performance specification" which the device is being updated to match, implying this as the target. The key performance metric cited is ARMS (Accuracy Root Mean Square).

The acceptance criteria for SpO2 accuracy are implicitly set by the previously cleared performance for adults, which is 1.5% ARMS. The submission aims to align the neonate performance with this.

Reported Device Performance:

ParameterRangeBiasPrecisionARMSSubjects
Initial Study Data (Neonates)
SaO270-100%0.082.582.5919
SaO285-100%-0.091.391.4012
SaO270-85%0.373.833.857
Aggregated Study Data (Neonates)
All Data70-100%0.1293.1823.18542

While the aggregated data shows an ARMS of 3.185%, the document states, "The analysis of the clinical data further supported the safe form, fit, and function of the RD SET Disposable Sensor on neonates. The Arms performance was calculated for reference purposes." And "The results of the clinical testing supported the subject device did not raise any different questions of safety and effectiveness as compared to the predicate device." This suggests that the clinical data, despite not strictly meeting the 1.5% ARMS in all ranges for neonates in the initial and aggregated studies, was deemed sufficient to support substantial equivalence due to the nature of the submission (labeling update, not a new device or significant modification) and the "reference purposes" of the ARMS calculation in this context. The core assertion is that the same device is being used, and the form, fit, and function for neonates are supported.

2. Sample size used for the test set and the data provenance

  • Initial Study: 19 neonatal subjects.
  • Aggregated Study: 42 neonatal subjects (including 22 pre-term neonates). This aggregation combines data from the initial study with data from "prior studies."
  • Data Provenance: The studies collected "convenience blood samples from an arterial line" in a "clinical environment." The document specifies that the aggregated data was from "3 different sites." The country of origin is not explicitly stated, but given the FDA submission, it's typically assumed to be conducted in the US or under comparable ethical/clinical standards acceptable to the FDA. The data is prospective clinical data collected for the purpose of verifying the device's performance on neonates.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

The ground truth for SpO2 measurements was established using a reference co-oximeter from arterial blood samples. This is a direct, objective measurement, not one established by human expert consensus or interpretation. Therefore, the concept of "number of experts" or their "qualifications" for establishing ground truth as typically applied to image-based AI studies (e.g., radiologists interpreting images) is not applicable here. The accuracy of the co-oximeter itself would be the relevant qualification.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

Since the ground truth is established by a reference co-oximeter on arterial blood samples, there is no adjudication method involving human experts for the test set.

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 physiological monitor (pulse oximeter), not an AI-assisted diagnostic imaging tool that would typically involve human readers interpreting AI outputs. The "AI" aspect is not explicitly mentioned or studied in the context of human reader improvement.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

The device itself provides the SpO2 measurements. The study assesses the accuracy of these measurements against a reference standard. While the device (Masimo Rad-97 with RD SET Disposable sensors) operates without human intervention in generating the SpO2 reading, the study framework is not typically referred to as a "standalone" or "algorithm only" study in the context of AI regulatory submissions. It's a performance validation study for a medical device. The "algorithm" here is the signal processing within the oximeter. The ARMS metric specifically reflects this standalone device accuracy.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

The ground truth used was objective reference measurements of SaO2 (arterial oxygen saturation) from arterial blood samples analyzed by a reference co-oximeter.

8. The sample size for the training set

The document does not mention a training set in the context of model development or machine learning. This submission is for a medical device (pulse oximeter) that relies on established physiological principles and signal processing, not a de novo AI/ML algorithm that requires distinct training and test sets in the typical sense. The device's underlying algorithms were presumably developed and validated in prior clearances (K180046). This submission is an update to the labeling for a specific patient population (neonates) using an existing sensor, justifying it with clinical performance data on that population.

9. How the ground truth for the training set was established

As there is no mention of a training set for an AI/ML model, this question is not applicable based on the provided document. The device's core technology and its existing cleared performance for adults underpin the rationale for extending the performance specifications to neonates.

5.3. Technological Characteristics

Principle of Operation

The principle of operations for the measurement capabilities of the Rad-97 product family does not change from the predicate (K180046) for the update to the RD SET Disposable sensor specifications for the neonate population. The principles of operation are still based upon the use of red and infrared wavelengths of light provided by an emitter and the detection of the signal from the light absorption of oxygenated blood and deoxygenated blood to provide functional oxygen saturation of hemoglobin (SpO2).

Mechanism of Action for Achieving the Intended Effect

The mechanism of action did not change from the predicate. The sensor is applied in the same way and to the same measurement sites as the predicate.

5.4. Summary of Technological Characteristics of Subject Device Compared to Predicate Device

The only difference between the subject device and the predicate is the SpO2 performance specification is updated to match that as it was previously cleared for the adult population as part of the predicate. There are no other difference between the predicate RD SET Disposable sensors to that of the subject device.

The subject device, RD SET Adhesive sensors with updated SpO2 specifications for the neonate population and the predicate device, have the following key similarities:

  • · Both devices have the same indicated populations;
  • · Both sensors have the same form factor and components;
  • · Both sensors have the same measurement application sites

The subject device, RD SET Adhesive sensor with update SpO2 performance specifications for the neonate population and the predicate device, have the following difference:

  • · Subject device has an updated SpO2 performance specification of 1.5% Arms. The SpO2 specification is being updated to match the adult population SpO2 performance specification previously cleared as part of the predicate.

Biocompatibility Testing 5.5.1.

As there were no changes associated with this submission, no additional biocompatibility testing was required to support the substantial equivalence.

Electrical Safety and EMC 5.5.2.

As there were no hardware changes associated with this submission, no additional electrical safety or EMC testing was required to support the substantial equivalence.

5.5.3. Software Verification and Validation Testing

As there were no software changes associated with this submission, no additional software verification and validation testing was required to support the substantial equivalence.

5.5.4. Mechanical Testing

As there were no mechanical changes associated with this submission, no additional mechanical testing was required to support the substantial equivalence.

5.5.5. Clinical Testing

As part of the submission, there was no changes made to the devices from the previous clearance in which the accuracy performance of the RD SET Disposable sensors was established to be 1.5% Arms validated on adults. As part of this submission, Masimo performed clinical testing on neonates using convenience arterial blood samples in accordance with the FDA guidance for Pulse Oximeters to verify the form. fit. and function of the RD SET Disposable sensors on neonate population. Although the RD SET Disposable sensors are not new or significantly modified the convenience samples were collected on neonatal population in order to provide greater assurance of the safe form, fit, and function on neonates.

As part of the study, convenience blood samples were collected from an arterial line of 19 neonatal subject's that were ≤ 1 month and weighing ≤ 4.5 kg. The SaO2 measurements from the blood samples using a reference co-oximeter were compared to the SpO2 measurements using a RD SET Disposable sensor. As the convenience blood samples were collected in a clinical environment dependent upon the availability of subjects, the results were subject to greater amounts of testing variability than would be expected in a controlled laboratory setting.

The analysis of the clinical data further supported the safe form, fit, and function of the RD SET Disposable Sensor on neonates. The Arms performance was calculated for reference purposes. See summary of Arms performance in table 5.5.1 below.
