The monitor is indicated for use by healthcare professionals whenever there is a need for monitoring the physiological parameters of patients. The monitor is intended to be used for monitoring and recording of, and to generate alarms, for, multiple physiological parameters of adults, pediatrics, and neonates. The monitor is intended for use by trained healthcare professionals in a hospital environment. The monitor is also intended for use during patient transport inside and outside of the hospital environment. The monitor is only for use on one patient at a time. It is not intended for home use. Not a therapeutic device. The monitor is for prescription use only. The ECG measurement is intended to be used for diagnostic recording of rhythm and detailed morphology of complex cardiac complexes (according to AAMI EC 11). ST segment monitoring is intended for use with adult patients only and is not clinically validated for use with neonatal and pediatric patients. The Predictive Temperature unit is intended for use with adult and pediatric patients in a hospital environment. The SSC Sepsis Protocol, in the ProtocolWatch clinical decision support tool, is intended for use with adult patients only. The derived measurement Pulse Pressure Variation (PPV) is intended for use with sedated patients receiving controlled mechanical ventilation and mainly free from cardiac arrhythmia. The PPV measurement has been validated only for adult patients. The transcutaneous gas measurement (tcGas) is restricted to neonatal patients only. BIS is intended for use under the direct supervision of a licensed health care practitioner or by personnel trained in its proper use. It is intended for use on adult and pediatric patients within a hospital or medical facility providing patient care to monitor the state of the brain by data acquisition of EEG signals. The BIS may be used as an aid in monitoring the effects of certain anesthetic agents. Use of BIS monitoring to help guide anesthetic administration may be associated with the reduction of the incidence of awareness with recall in adults during general anesthesia and sedation.

The Philips IntelliVue Patient Monitors family comprises the multiparameter patient monitor series: MP2, X2, MP5, MP5T, MP5SC, MP20, MP30, MP40, MP50, MP60, MP70, MP80, MP90 and MX600, MX700, and MX800. Each monitor consists of a display unit including built-in or separate central processing unit (CPU) and physiological measurement modules. All monitors share the same architecture of CPU units and exactly the same software is executed on each monitor. The monitors measure physiological parameters such as: Sp02, pulse, ECG, arrhythmia, ST, QT, respiration, invasive and noninvasive blood pressure, temperature, CO2, spirometry, C.O., CCO, tcp02/ tcpCO2, S02, Sv02, Scv02, EEG, and BIS. They generate alarms, record physiological signals, store derived data, and communicate derived data and alarms to the central station. IntelliVue series MP2, X2, MP5, MP5T, MP5SC, MP20, and MP30 are robust, portable, lightweight, compact in size and modular in design patient monitors with interfaces to dedicated external measurement devices. Models MP2, X2, MP5, MP5T, and MP5SC also incorporate multiple built-in physiological measurements. IntelliVue series MP40, MP50, MP60, MP70, MX600, MX700, and MX800 are patient monitors with built-in central processing unit, flat panel display and interfaces to dedicated external measurement devices. Models MX600, MX700, and MX800 have widescreen displays. IntelliVue series MP80 and MP90 are patient monitors with flat panel display and central processing unit as separate components. They have interfaces to dedicated external measurement devices.

Here's a breakdown of the acceptance criteria and the study information based on the provided text, structured as requested:

Acceptance Criteria and Device Performance Study for Philips IntelliVue Patient Monitors (Software Revision J.04)

Overview:
The submission describes a software modification to existing Philips IntelliVue Patient Monitors (MP2, X2, MP5, MP5T, MP5SC, MP20, MP30, MP40, MP50, MP60, MP70, MP80, MP90, MX600, MX700, and MX800) to introduce a new SpO2 intelligent alarm delay feature called 'Smart Alarm Delay'. The study aims to demonstrate that this modified device is as safe and effective as the predicate devices.

1. Table of Acceptance Criteria and Reported Device Performance

The document does not explicitly present a quantitative table of acceptance criteria with corresponding performance metrics for the 'Smart Alarm Delay' feature in the format often seen for diagnostic devices (e.g., sensitivity, specificity, accuracy). However, the "Summary of V&V activities" section outlines the general performance goals and outcomes.

2. Sample Size and Data Provenance for the Test Set

• Sample Size: The document does not specify the exact number of individuals (test persons) involved in the clinical evaluation. It refers to "two user groups - one consisting of physicians and one consisting of nurses" and later "the vast majority of test persons." This suggests a qualitative assessment rather than a statistically powered performance study.
• Data Provenance: Not explicitly stated, but clinical evaluation of user understanding implies prospective testing with healthcare professionals. The country of origin for this specific clinical evaluation is not mentioned.

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

• The "clinical evaluation" appears to focus on user comprehension and acceptance, not on establishing a traditional clinical "ground truth" for diagnostic accuracy.
• Number of Experts: Two user groups were formed: "one consisting of physicians and one consisting of nurses." The exact number of individuals within each group is not provided.
• Qualifications of Experts:
  • Physicians
  • Nurses
  • No specific years of experience or subspecialty are mentioned.

4. Adjudication Method for the Test Set

Not applicable. The clinical evaluation described is a qualitative assessment of user understanding and perception, not a diagnostic accuracy study requiring adjudication of results.

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

No. The document describes a software modification to an existing patient monitor to add an intelligent alarm delay feature. The "clinical evaluation" focused on user understanding and acceptance of this feature, not on comparing reader performance with and without AI assistance.

6. Standalone Performance Study (Algorithm Only)

No, not in the traditional sense of a standalone diagnostic algorithm performance study. The modification is an alarm delay feature within an existing monitoring system. The document states:

• "The new 'Smart Alarm Delay' feature is isolated from the SpO2 measurement algorithm, i.e. signal acquisition and numeric processing."
• "The devices hardware and all accessories including, but not limited to the SpO2 sensors remain completely unchanged."
• "The modification does not affect device performance in general and device accuracy in particular."
• Performance aspects covered by ISO 9919 from prior V&V are considered still valid.

This indicates that the fundamental SpO2 measurement accuracy itself was not re-evaluated as a standalone algorithm performance, as the algorithm for SpO2 measurement remained unchanged. The focus was on the alarm delay logic and its user-facing implications.

7. Type of Ground Truth Used

For the "clinical evaluation" regarding the 'Smart Alarm Delay' feature, the "ground truth" appears to be user understanding and subjective opinion as gathered directly from physicians and nurses. For the core SpO2 measurement, the ground truth and performance validation are based on prior verification and validation activities conducted according to ISO 9919 for the predicate device, which are deemed still valid.

8. Sample Size for the Training Set

Not applicable. This submission is for a software modification adding an alarm delay feature, not a machine learning or AI algorithm that requires a dedicated training set for model development. The 'Smart Alarm Delay' is described as being "based on the same fundamental principle" as the predicate's 'SatSeconds' alarm management technique, implying a rule-based or empirically derived logic rather than a learned model.

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

Not applicable, as no training set for a machine learning model was described or used.

1. Table of Acceptance Criteria and Reported Device Performance

The document broadly states that the device successfully met its specifications and performed reliably. Specific, quantifiable acceptance criteria (e.g., specific accuracy metrics for data collection, thresholds for system response times) and their corresponding reported performance values are not explicitly provided in this summary. The "performance" is described in general terms of functionality and clinical usefulness.

2. Sample Size for the Test Set and Data Provenance

The summary does not specify a sample size for any test set (e.g., number of patients, number of data points, or number of simulated scenarios).

Regarding data provenance:

• Country of Origin: Not specified.
• Retrospective/Prospective: Not specified for the performance tests, but the "Clinical Evaluation" implies prospective use in a clinical setting to assess usefulness and acceptance by users.

3. Number of Experts and Qualifications for Ground Truth

The summary mentions "clinical users" in the context of the "Clinical Evaluation" for user acceptance. However, it does not specify the number of experts, their qualifications (e.g., radiologists with X years of experience), or their role in establishing ground truth for any performance metrics. The ground truth for this device appears to be primarily related to system functionality and user acceptance, rather than a diagnostic output requiring expert consensus.

4. Adjudication Method

The summary does not mention any adjudication method (e.g., 2+1, 3+1, none) for the test set or for establishing ground truth.

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

The document does not indicate that a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was done. The device is a Clinical Information Management System and cableless measurement pods, which are generally not subject to MRMC studies in the same way an AI-powered diagnostic tool would be. The focus is on data collection, management, and display.

6. Standalone Performance Study

The summary mentions "Non-Clinical Performance Tests (bench testing)" and "Functionality testing on the new IntelliVue Guardian Software," which imply standalone or algorithm-only evaluation of the software and its components. However, it does not provide specific metrics or results from such a standalone study beyond a general statement of "confirmed static and dynamic performance... according to the specifications."

7. Type of Ground Truth Used

The "ground truth" for the various tests appears to be established as follows:

• Non-Clinical Performance Tests: Adherence to "specifications" for static and dynamic performance. This likely refers to predefined technical requirements and expected system behavior.
• Clinical Evaluation: "Clinical usefulness" and "acceptance by the clinical users." This suggests a qualitative assessment based on user feedback and observation in a clinical setting.
• Functionality Testing: Verification against expected functional behavior of the software and hardware components.

There is no mention of pathology, expert consensus on diagnostic outcomes, or long-term outcomes data as ground truth, as these would typically apply to diagnostic or prognostic devices.
