It facilitates clinical data acquisition and analytical assessment for cardiac catheterization, invasive radiology and electrophysiology laboratories.

    AI/ML Overview

    The provided text focuses on the 510(k) summary for the Xper Information Management/Physiomonitoring 5 and/or Vascular 5 system, Patient Care Console and Central Station, and ECG Management system. It describes the device, its intended use, and states its substantial equivalence to a predicate device based on "Performance Testing as well as the Hazard analysis." However, it does not provide specific acceptance criteria, detailed results from performance tests, or information about specific studies that demonstrate the device meets acceptance criteria.

    The document states that the modifications to the device primarily involve:

    • Introduction of a new trade name.
    • GUI updates.
    • Upgrades in hardware and software to facilitate integration of the latest technology.

    It explicitly mentions that the modified device has the "same technological characteristics as the legally marketed predicate device (K033030)." This strongly suggests that the focus of the 510(k) submission was on demonstrating that these changes did not adversely affect the device's fundamental safety and effectiveness, rather than performing entirely new clinical or detailed performance studies against novel acceptance criteria.

    Therefore, for most of the requested information, the answer will be that the details are not available in the provided text.

    Here's an attempt to answer the questions based on the available information:

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

    Acceptance CriteriaDevice Performance Reporting
    Not explicitly stated in the document. The document implies that the acceptance criterion was "substantial equivalence" to the predicate device K033030."The Performance Testing as well as the Hazard analysis for the Xper Information Management system provides objective evidence that it is substantially equivalent the predicate CALYSTO Series IV system." No specific performance metrics or thresholds are reported.

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

    Not provided in the document. The text refers to "Performance Testing" and "Hazard analysis" but does not detail the nature of these tests, the data sources, or sample sizes.

    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)

    Not provided in the document. This type of information would typically be detailed in a more comprehensive clinical study report, which is not part of this 510(k) summary. Given the nature of the device (physiomonitoring and information management, not diagnostic interpretation), "ground truth" in the diagnostic sense might not be applicable in the same way as for an AI-powered diagnostic tool. The document states "Its users, responsible to interpret the data made available, will be professional health care providers."

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

    Not provided in the document.

    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 done. This device is described as a physiomonitoring and information management system, not an AI-assisted diagnostic tool that aids human readers in interpretation. The document explicitly states for the ECG Management System that it "does not provide interpretive functions."

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

    Not applicable in the context of this device as described. The device "facilitates clinical data acquisition and analytical assessment" and its "users, responsible to interpret the data made available, will be professional health care providers." The ECG Management System "does not provide interpretive functions."

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

    Not explicitly stated. Given that the device handles "physiologic/hemodynamic monitoring" and "clinical data acquisition," the "ground truth" for its performance would likely relate to the accuracy of physiological measurements, data integrity, system functionality, and adherence to safety standards. However, the document does not specify how this "ground truth" was established for testing purposes.

    8. The sample size for the training set

    Not applicable/Not provided. This device is not described as an AI/ML device that requires a training set in the conventional sense for learning patterns or making predictions. It's a system for managing and displaying physiological data.

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

    Not applicable/Not provided. As above, this is not an AI/ML device requiring a training set with established ground truth for learning.

    Device Description

    The modified device has the same intended use as the legally marketed predicate device. It is intended to be used for complete physiologic/hemodynamic monitoring and information gathering. It facilitates clinical data acquisition and analytical assessment for cardiac catheterization, invasive radiology and electrophysiology laboratories.

    AI/ML Overview

    The provided text describes modifications to the CALYSTO Series IV Physio-monitoring and Information System. The submission is a 510(k) premarket notification, which focuses on demonstrating substantial equivalence to a legally marketed predicate device rather than providing detailed acceptance criteria and a comprehensive study report in the way a PMA submission might.

    Therefore, much of the requested information regarding acceptance criteria, sample sizes, expert involvement, and ground truth for a de novo device or a device with new functionality is not explicitly detailed in this document. The focus here is on showing that the modifications do not alter the fundamental safety and effectiveness of the device compared to its predicate.

    Here's an analysis based on the provided text:

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

    The document summarizes the testing as: "Verification, validation and testing activities establish the performance, functionality, and reliability characteristics of the modified device with respect to the predicate. Pass/Fail criteria were based on the specifications cleared for the predicate device and the test results showed substantial equivalence."

    This indicates that the acceptance criteria were the specifications of the predicate device, and the reported device performance was that it met these specifications, demonstrating substantial equivalence. Specific quantitative criteria and results for parameters like accuracy, precision, sensitivity, or specificity for the new modules are not provided in this summary.

    Acceptance Criteria (Inferred)Reported Device Performance
    Performance, functionality, and reliability characteristics of the modified device are equivalent to the predicate device (K033030).Test results showed substantial equivalence to the predicate device.
    Specifications of the proposed Respironics Capno 5 End Tidal CO2 and Masimo MX-1 pulse oximetry modules are equivalent to the currently cleared predicate device's modules (Nellcor MP 506 for pulse oximetry).The specifications and accuracy of the proposed modules are equivalent to the currently legally marketed predicate device (K033030).
    Modifications do not change the intended use or operating parameters of the system.The modifications do not change the intended use or operating parameters of the system. No contraindications have been added or removed as a result of the modifications.
    No new safety concerns introduced by the modifications.Implied by the substantial equivalence determination and the statement that "modifications do not change the intended use or operating parameters of the system" and "no contraindications have been added or removed."

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

    • Sample Size: Not specified. The document states "Verification, validation and testing activities," but does not detail the nature or scope of these activities in terms of sample size for clinical or simulated data.
    • Data Provenance: Not specified. Given the nature of medical device testing for 510(k) modifications, the testing would typically involve laboratory and/or simulated clinical environments. It's highly unlikely to involve patient data provenance in the way a diagnostic AI product might.

    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):

    Not applicable/Not specified. This submission is for modifications to a physiological monitor, not a diagnostic device that requires expert interpretation to establish ground truth for a test set. The validation would primarily focus on technical specifications and accuracy against established calibration standards or reference devices, not human expert consensus.

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

    Not applicable/Not specified. Adjudication methods are typically used when human interpretation or diagnosis is part of establishing ground truth for diagnostic devices. This document describes a physiological monitoring system.

    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. This device is a physiological monitor and central station system. It does not appear to incorporate AI for diagnostic assistance that would warrant an MRMC study comparing human reader performance.

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

    The device itself is a standalone physiological monitor. The testing would have evaluated the performance of the integrated modules (End Tidal CO2 and pulse oximetry) in a standalone manner against their specifications. The document states, "The specifications and accuracy of the proposed modules are equivalent to the currently legally marketed predicate device." This implies standalone testing of component performance.

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

    The ground truth for this type of device (physiological monitor) would be established by:

    • Reference standards: Calibrated test equipment, simulated physiological signals, or comparison against established "gold standard" medical devices.
    • Manufacturer specifications: The performance specifications provided by the manufacturers of the integrated modules (Respironics and Masimo), which would have been validated during their own development.

    8. The sample size for the training set:

    Not applicable. This device does not appear to use machine learning or AI that would require a "training set" in the conventional sense for a diagnostic algorithm. The modifications involve integrating established physiological monitoring modules.

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

    Not applicable, as there is no apparent training set for an AI algorithm.

    AI/ML Overview

    I am sorry, but the provided text does not contain the necessary information to answer your request regarding the acceptance criteria and study details for the Witt Biomedical Corporation Central Station with Advanced Patient Care Monitoring System.

    The document is a 510(k) clearance letter from the FDA, which confirms that the device is substantially equivalent to a predicate device and can be marketed. It includes the device name, indications for use, and regulatory classification but does not detail the specific performance acceptance criteria, study design, sample sizes, ground truth establishment, or expert qualifications that would be found in a clinical study report or performance evaluation.

    Therefore, I cannot provide a table of acceptance criteria, reported device performance, sample sizes, data provenance, number of experts, adjudication methods, MRMC study results, standalone performance, type of ground truth used, or training set details based on this document.
