The IntelliVue Patient Monitors MX750 and MX850 acquire multiple physiological patient signals, display measurement values, waves and trends, generate physiological and technical alarms, provide data recording and support patient data management. They operate with the external Measurement Modules and the IntelliVue 4-Slot Module Rack FMX-4, which establishes the connection between the individual plug-in measurement modules and the MX750 and MX850 monitors.

The monitors support multiple non-invasive measurements such as ECG, arrhythmia, ST, QT, SpO2, respiration rate, pulse rate, heart rate, invasive and non-invasive blood pressure, temperature, CO2, tcpO2/ tcpCO2, C.O., CCO, intravascular SO2, SvO2, ScvO2, EEG, BIS, NMT, and gas analysis.

The monitors offer a monitoring solution optimized for the surgical, cardiac, medical and neonatal care environments. They are located in the patient vicinity at the bedside. These devices have a color display with a touch-screen as a primary input device. They also support keyboard and pointing devices such as a mouse.

The monitor models MX750 and MX850 differ mainly in size. While MX750 has a 19" flat panel display, MX850 has a 22″ display.

This K221348 510(k) summary document describes the Philips IntelliVue Patient Monitor MX750 and MX850. It primarily focuses on demonstrating substantial equivalence to predicate devices, particularly regarding the addition of compatibility with external Masimo measurement devices.

Based on the provided document, here's a breakdown of the acceptance criteria and study information:

1. Table of Acceptance Criteria and Reported Device Performance

The document does not explicitly present a table of specific acceptance criteria (e.g., accuracy, precision thresholds) for each physiological parameter measured by the IntelliVue Patient Monitors MX750 and MX850, nor does it provide detailed reported performance values for these criteria in the context of this specific 510(k) submission.

Instead, the document states:

• "Performance specifications of all measurement characteristics, including measurement principles, methods, algorithms, and all detailed performance specifications remain unchanged" from the predicate devices.
• "performance specifications of the added external measurements Masimo O3 Masimo IRMA CO2 and ISA CO2 Masimo SedLine remain unchanged."

This implies that the acceptance criteria and reported device performance for the core functionalities of the IntelliVue Patient Monitor MX750 and MX850 (excluding the newly added external measurements) are inherently covered by the predicate devices they are compared against. For the newly integrated Masimo modules, their performance criteria and data are derived from their own prior clearances (K162603, K123043, K171121, K172890).

Therefore, a table cannot be directly constructed from this document as it doesn't provide new, specific performance data for the current submission's acceptance criteria beyond referencing existing performance.

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

The document states:

• "Non-clinical Bench Tests: There were no new questions of safety or effectiveness introduced as a result of using this device."
• "Clinical Studies: The subject devices, like the primary predicate devices, did not require clinical trials. Any clinical studies performed for the Masimo O3, IRMA CO2, ISA CO2 and SedLine parameters are still valid as the measurements are not modified; they are only being connected to an additional host patient monitor."

This indicates that no new test set (clinical or otherwise) with a specific sample size was used for this 510(k) submission to evaluate the primary IntelliVue devices' performance beyond what was established for their predicates. The assessment relies on the existing validation of the predicate IntelliVue device and the individual Masimo modules.

Therefore, sample sizes for a new test set are not applicable here. The provenance of existing data would refer to the previous submissions for the predicate IntelliVue devices and the Masimo modules, which are not detailed in this document.

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

As no new clinical studies or test sets were conducted for this 510(k) submission to establish new performance data, there is no information provided regarding a number of experts used to establish ground truth or their qualifications. The submission asserts that the performance characteristics (and thus, the ground truth establishment) of the individual components (IntelliVue monitor and Masimo modules) remain unchanged from their prior clearances.

4. Adjudication Method for the Test Set

Since no new test set was generated for this 510(k) submission (as per point 2), no adjudication method specific to this submission's test set is detailed.

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

The document states that "The subject devices, like the primary predicate devices, did not require clinical trials." This implies that no MRMC comparative effectiveness study was performed for this submission. The device is a patient monitor, not typically evaluated with MRMC studies in the way imaging AI algorithms are.

6. Standalone Performance Study (i.e., algorithm only without human-in-the-loop performance)

The document focuses on the integration of external modules into an existing patient monitor. While the individual Masimo modules (O3, IRMA CO2, ISA CO2, SedLine) likely had standalone performance studies as part of their original clearances, this 510(k) document does not report new standalone performance studies for the integrated system or its individual components in this context. The core assertion is that the measurements are not modified, only the host monitor connection.

7. Type of Ground Truth Used

Given that no new studies were conducted, the document implicitly relies on the ground truth established during the previous clearances of the predicate IntelliVue monitors and the Masimo modules. The specific types of ground truth for these physiological parameters would typically involve:

• Reference standard measurements: Comparison against highly accurate and precise clinical instruments for parameters like ECG, SpO2, blood pressure, CO2.
• Clinical observation and expert interpretation: For conditions like arrhythmia detection (ECG) or state of brain monitoring (EEG/BIS/SedLine), ground truth might involve expert review of physiological waveforms and patient state.
• Pathology/Outcomes data: Not explicitly mentioned or typically applicable for patient monitoring as a primary ground truth.

However, this document does not detail the specific ground truth methodologies used in those prior studies.

8. Sample Size for the Training Set

The document describes a 510(k) submission for a patient monitor and the integration of external modules. This type of device relies on established algorithms for physiological parameter measurement, rather than a machine learning model that requires a distinct "training set" in the common sense of AI/ML software. Therefore, the concept of a "training set sample size" as typically used for AI/ML does not directly apply or is not detailed here. The algorithms used in the Masimo modules and the Philips monitor were developed and validated, but this process doesn't align with a "training set" in the AI/ML context.

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

As explained in point 8, the concept of a "training set" in the AI/ML sense is not applicable or detailed in this document for these types of patient monitoring algorithms. Therefore, information on how ground truth for a training set was established is not present. The algorithms' foundational accuracy would have been established through a combination of engineering, physiological principles, and validation against clinical reference standards, as mentioned above for "Type of Ground Truth."
