The Masimo Root Monitoring System and Accessories (Root) is a multifunctional device that monitors vital signs for neonatal to adult patients. Parameters monitored by Root are from cleared measurement modules and their corresponding accessories, consisting of:

• . Masimo Radical-7 and Radius-7 Pulse CO-Oximeter measurement modules and accessories (i.e. RD SET disposable sensors, RD Rainbow sensors, RAS-45 or RRa sensors) with technologies for the monitoring of non-invasive functional oxygen saturation of arterial hemoglobin (SpO2), pulse rate, carboxyhemoglobin saturation (SpCO), methemoglobin saturation (SpMet), total hemoglobin concentration (SpHb), and respiratory rate (RRa);
• Masimo Sweden ISA-Infrared Sidestream Gas Analyzer measurement modules (ISA) and accessories (Nomoline product family) with technologies for breathing gases and respiratory rate monitoring, including inspired/expired gases during anesthesia, recovery and respiratory care;
• Masimo Sedline Sedation Monitor measurement module and accessories (i.e. RD . Sedline EEG sensor) with technologies for state of the brain by real-time data acquisition and processing of EEG signals and Patient State Index (PSI) which is an EEG variable that is related to the effect of anesthetic agents;
• Temperature measurement module and accessories (i.e. temperature probe) with technologies for oral/axillary body temperature measurements; and
• . Non-invasive blood pressure measurement module and accessories (i.e. reuse and disposable pressure cuffs) with technologies for systolic, diastolic and mean arterial pressure (MAP) measurements.

Root is intended to be used as a user interface to facilitate access control and monitoring device functions. Root displays patient monitoring information from the connected modules. Visual alarms are shown on the Root display and audible alarms are generated through the Root internal speaker. The user accesses the wired or wirelessly connected modules' monitoring functions, using the Root display. When the module is disconnected from Root, the monitoring information from the module is no longer displayed on Root. Data from connected modules, including patient monitoring data, can be communicated to network systems such as the Patient SafetyNet (K071047) and hospital EMR. Root also functions as a pass-through means for communicating information between connected devices and network systems.

The Root under K151644 consists of various measurement modules, including the ISA product family (ISA) and corresponding accessories, Nomoline product family (Nomoline).

The provided text describes a 510(k) premarket notification for the Masimo Root Monitoring System and Accessories. It outlines the device's indications for use, technological characteristics, and a comparison to predicate devices, focusing on the ISA and Nomoline components.

No clinical studies are mentioned for the subject device to support acceptance criteria within this document. The document explicitly states: "Clinical testing was not performed with the subject device, Root with ISA and Nomoline, to support substantial equivalence."

Therefore, I can only provide information based on the non-clinical testing and general specifications mentioned.

Here's a breakdown of the requested information based solely on the provided text:

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

The document provides "Specifications" for the Root system and the ISA module, which can be interpreted as acceptance criteria for the non-clinical tests conducted. The "reported device performance" is implicitly that the device met these specifications, as the conclusion states the non-clinical testing "demonstrates that the subject device...is substantially equivalent to its predicate."

2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

The document focuses on non-clinical (bench) testing. It does not specify sample sizes for individual tests (e.g., how many devices were tested for electrical safety or how many times a given parameter was measured for accuracy).

• Sample Size: Not specified in terms of distinct units or number of measurements for bench tests.
• Data Provenance: Not specified, but generally, bench testing would be conducted in a laboratory setting, likely in the country of origin of the manufacturer (USA, given the Masimo Corporation address being Irvine, California). There is no indication of retrospective or prospective data as it is non-clinical.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

This is not applicable as the testing described is non-clinical bench testing, not a clinical study involving human assessment of ground truth.

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

Not applicable for non-clinical bench testing.

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

Not applicable. The document explicitly states "Clinical testing was not performed." This device is a monitoring system and accessories, not an AI diagnostic tool that would typically involve human readers.

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

The document describes the performance of measurement modules (e.g., ISA gas analyzer) that are part of the system. These modules operate standalone in terms of their measurement capabilities, but they are integrated into the Root system for display and control. The "reported device performance" in the table above implicitly refers to this standalone measurement performance meeting specifications in a bench setting.

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

For non-clinical bench testing, the "ground truth" would be established by:

• Reference instruments (e.g., calibrated gas mixtures for ISA accuracy).
• Standardized test conditions (e.g., specified temperature, humidity, power input).
• Technical standards (e.g., dimensional measurements, material properties).
• Compliance with recognized standards (IEC-60601-1, ISO 80601-2-55, ISO-10993 series).

8. The sample size for the training set

Not applicable. The document does not describe any machine learning or AI components requiring a training set in the context of this 510(k) submission.

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

Not applicable. No training set is mentioned.
