    AirLife Adult Heated Wire Circuit

    AI/MLSaMDIVD (In Vitro Diagnostic)TherapeuticDiagnosticis PCCP AuthorizedThirdpartyExpeditedreview
    Intended Use

    The AirLife Adult Heated Wire Circuit is intended to warm breathing gases before they enter a patient's airway. The AirLife Adult Heated Wire Circuit is used with the adult patient population that requires mechanical ventilation, positive pressure breathing or general medical gases. The product is single use device, non-sterile and used in professional healthcare environments and intra-hospital transport environments under a doctor's supervision and by skilled clinicians. The AirLife Adult Heated Wire Circuit is compatible to the Fisher & Paykel MR850 humidifier.

    Device Description

    The heated breathing circuit is intended to deliver and warm breathing gases before they enter the patient's airway. It is provided non sterile for single patient use. The heated breathing circuit is used with Fisher and Paykel heated humidifier.

    AI/ML Overview

    The provided document is a 510(k) premarket notification for a medical device called the "AirLife Adult Heated Wire Circuit." This type of document is for demonstrating substantial equivalence to a legally marketed predicate device, rather than proving a new device's performance against clinical acceptance criteria in the same way a novel device might.

    The "acceptance criteria" and "study that proves the device meets the acceptance criteria" in this context refer to engineering and performance tests against recognized standards for breathing circuits and humidifiers, not clinical performance measures like sensitivity, specificity, or reader agreement for an AI diagnostic device.

    Here's the breakdown of the information based on the document:

    1. Table of Acceptance Criteria and Reported Device Performance

    The document does not explicitly present a table of acceptance criteria with corresponding performance statistics in a pass/fail format typical for a clinical study of an AI device. Instead, it lists the performance characteristics tested and the standards they comply with, implying that meeting these standards constitutes the acceptance criteria. The "reported device performance" is implicitly that the device did meet these standards, as stated in the conclusion.

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

    This document does not specify a "test set" in the context of clinical data for AI benchmarking. The tests performed are engineering and performance evaluations of the device itself (e.g., length, resistance, leakage). The document does not provide details on the sample size (number of devices tested), the provenance of the data (country of origin), or whether the testing was retrospective or prospective. These are typically internal validation tests by the manufacturer.

    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. This device is not an AI diagnostic tool that requires expert human interpretation to establish ground truth for a test set. The "ground truth" here is defined by the technical specifications outlined in the referenced ISO and IEC standards.

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

    Not applicable. There is no human adjudication process involved as this is a technical device performance evaluation against standards.

    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 is not an AI-assisted diagnostic device, and therefore, no MRMC study or assessment of human reader improvement with AI assistance was conducted or reported.

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

    Not applicable. This is a physical medical device (heated wire circuit), not an algorithm.

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

    The "ground truth" for this device's performance is established by the technical specifications and test methodologies outlined in the referenced international standards (e.g., ISO 5367, ISO 8185, IEC 60601-1, ISO 10993 series). The device's performance is measured against these quantitative and qualitative criteria defined by the standards.

    8. The sample size for the training set

    Not applicable. This is not a machine learning or AI device that requires a training set.

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

    Not applicable. There is no training set for this type of device.
