Intended Use

The BeneVision N12N15/N17/N19/N22 patient monitors are intended for monitoring, displaying, storing, storing, alarming, and transferring of multiple physiological parameters including ECG (3-lead, 5-lead or 12-lead selectable, Arrhythmia Detection, ST Segment Analysis, QT Analysis, and Heart Rate (HR)), Respiration Rate (Resp), Temperature (Temp), Pulse Oxygen Saturation (SpO2), Pulse Rate (PR), Non-invasive Blood Pressure (NIBP), Invasive Blood Pressure(IBP), Pulmonary Artery Wedge Pressure (PAWP), Cardiac Output (C.O.), Continuous Cardiac Output (CCO), Mixed/Central Venous Oxygen Saturation (SvO2/ScvO2), Carbon Dioxide (CO2), Oxygen (O2), Anesthetic Gas (AG), Impedance Cardiograph (ICG), Bispectral Index (BIS), Respiration Mechanics (RM), Neuromuscular Transmission Monitoring (NMT), Electroencephalograph (EEG), and Regional Oxygen Saturation (rSO2). The system also provides an interpretation of resting 12-lead ECG.

All the parameters can be monitored on single adult, pediatric, and neonatal patients except for the following: · The arrhythmia detection, BIS, RM, CCO, SvO2/ScvO2, PAWP, and NMT monitoring are intended for adult and pediatric patients only:

· C.O. monitoring is intended for adult patients only;

• ICG monitoring is intended for only adult patients who meet the following requirements: height: 122 to 229cm, weight: 30 to 155kg.

· rSO2 monitoring is intended for use in individuals greater than 2.5kg.

The monitors are to be used in healthcare facilities by clinical professionals or under their guidance. They should only be used by persons who have received adequate training in their use. The BeneVision N12/N15/N17/N19/N22 monitors are not intended for helicopter transport. hospital ambulance, or home use.

BeneVision N1 Patient Monitor:

The BeneVision N1 Patient Monitor is intended for monitoring, reviewing, storing , alarming, and transferring of multiple physiological parameters including ECG (3-lead, 5-lead or 12-lead selectable, Arrhythmia Detection, ST Segment Analysis, and Heart Rate (HR)), Respiration (Resp), Temperature (Temp), Pulse Oxygen Saturation (SpO2), Pulse Rate (PR), Non-invasive Blood Pressure (NIBP), Invasive Blood Pressure (IBP) , Pulmonary Artery Wedge Pressure (PAWP), Carbon Dioxide (CO2) and Oxygen (O2). The system also provides an interpretation of resting 12-lead ECG.

All the parameters can be monitored on single adult, pediatric, and neonatal patients except for the following:

• The arrhythmia detection and PAWP is intended for adult and pediatric patients only

The BeneVision N1 monitor is to be used in healthcare facilities. It can also be used during patient transport inside and outside of the hospital environment. It should be used by clinical professionals or under their guidance. It should only be used by persons who have received adequate training in its use. It is not intended for home use.

AI/ML Overview

The provided text is a 510(k) Summary for the Mindray BeneVision N Series Patient Monitors. It mainly focuses on demonstrating substantial equivalence to a predicate device rather than presenting a detailed study with acceptance criteria and specific performance metrics in the format requested.

The document discusses functional and system level testing and bench testing to validate performance and ensure specifications are met, but it does not provide a table of acceptance criteria alongside reported device performance data, nor does it detail the specifics of such a study.

Here's a breakdown of the requested information based on the provided text, highlighting what is not available:

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

    • Not Available. The document states that "functional and system level testing showed that the devices continue to meet specifications and the performance of the device is equivalent to the predicate" and "the subject device meets its accuracy specification." However, it does not provide the specific numerical acceptance criteria or the reported performance data in a table. It only lists measurement ranges and accuracies for various parameters (ECG, Respiration Rate, Temperature, SpO2, Pulse Rate, NIBP, IBP, C.O., CCO, SvO2/ScvO2, CO2, O2, AG, ICG, RM, NMT, EEG, rSO2) under the "Technological Comparison" tables (Table 2 and Table 3). These are presented as specifications rather than acceptance criteria for a study.
  2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

    • Not Available. The document mentions "functional and system level testing" and "bench testing" but provides no details on the sample size of data used for these tests, nor its provenance (country, retrospective/prospective nature).
  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 Available. This device is a patient monitor, and its performance is assessed against established physical measurement standards and algorithms, not typically against expert interpretation of data for ground truth in the way an AI diagnostic algorithm might be (e.g., radiologists for medical images). The document does not mention any expert review process for determining ground truth.
  4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

    • Not Applicable / Not Available. As mentioned above, the assessment appears to be against physical specifications and consensus standards, not an expert-adjudicated ground truth.
  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, not done. The document does not mention an MRMC study or any assessment of human reader improvement with AI assistance. This device is a patient monitor providing physiological parameters, not an AI-assisted diagnostic tool for human interpretation.
  6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

    • N/A (Implicitly standalone for most parameters against physical standards). The performance evaluation described largely implies standalone testing against specifications and standards. For example, for ECG, SpO2, NIBP, etc., the device's internal algorithms process signals and provide readings, which are then assessed for accuracy. The "reporting" is of the device's ability to measure parameters correctly, not its ability to assist a human.
  7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

    • Physical Standards and Reference Devices/Methods. The ground truth for the measurements would be established by validated physical standards, calibrated equipment, and comparison to reference methods (e.g., for invasive blood pressure, cardiac output). The document implies validation against these types of established standards and specifications.
  8. The sample size for the training set

    • Not Applicable / Not Available. The document does not describe the development or training of AI algorithms that would require a "training set" in the context of machine learning. The patient monitor's algorithms are based on established physiological signal processing, not deep learning models.
  9. How the ground truth for the training set was established

    • Not Applicable. See point 8.

§ 870.1025 Arrhythmia detector and alarm (including ST-segment measurement and alarm).

(a)
Identification. The arrhythmia detector and alarm device monitors an electrocardiogram and is designed to produce a visible or audible signal or alarm when atrial or ventricular arrhythmia, such as premature contraction or ventricular fibrillation, occurs.(b)
Classification. Class II (special controls). The guidance document entitled “Class II Special Controls Guidance Document: Arrhythmia Detector and Alarm” will serve as the special control. See § 870.1 for the availability of this guidance document.
