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.

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 MR850.

The provided text describes a 510(k) premarket notification for a medical device called the "AirLife Infant Single Limb Heated Wire Circuit." It focuses on demonstrating substantial equivalence to a predicate device. The information required for outlining acceptance criteria and a study proving a device meets them is not fully contained within this document because it is a submission for substantial equivalence, not a detailed clinical study report for a novel device.

However, based on the provided text, I can infer and extract some relevant details pertaining to performance testing and general acceptance principles for this type of device.

Here's an attempt to answer your request using the available information, with clear indications of where information is directly stated versus inferred as typical for a 510(k) submission:

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

The document lists performance characteristics and the relevant standards they were tested against. For a 510(k) submission demonstrating substantial equivalence, the "acceptance criteria" are implied to be meeting the requirements set forth in these standards. The "reported device performance" is a general statement of compliance, rather than specific numerical results.

Regarding the study proving the device meets acceptance criteria:

The document broadly states: "The following tests were performed for the proposed device to support the substantial equivalence decision," and "The test results demonstrate that the device is as safe and effective as the predicate and therefore substantially equivalent to the predicate device." This indicates that a series of performance bench tests were conducted to verify compliance with the listed international standards (ISO, IEC, AAMI). These are typically laboratory-based engineering and material tests, not clinical studies involving human subjects in an "AI" context.

2. Sample size used for the test set and the data provenance

• Sample Size: Not specified in the provided document. For engineering/bench tests, sample sizes would typically be determined by the specific standard's requirements (e.g., n=3, n=5, n=10 per test), but these details are not present.
• Data Provenance: The tests were performed by the manufacturer, CareFusion Inc., in support of their 510(k) submission to the FDA. The country of origin of the data would be the location where CareFusion conducted these tests, which is not explicitly stated but can be inferred as the US based on the company's US address. The data is retrospective in the sense that the tests were completed before the submission.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

This is not applicable to this type of device and study. The testing described involves physical and electrical performance verification against defined standards, not evaluation by human experts or clinical ground truth.

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

This is not applicable. Adjudication methods like 2+1 or 3+1 are used in clinical studies where expert consensus is needed for image interpretation or diagnosis. Bench testing against standards does not typically involve such adjudication.

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

This is not applicable. This device is a heated breathing circuit, not an AI-powered diagnostic or assistive tool. Therefore, no MRMC study or AI-related comparative effectiveness was conducted or reported.

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

This is not applicable. This device does not involve any algorithms or AI for standalone performance evaluation.

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

The "ground truth" for this device's performance testing is adherence to the technical specifications and safety requirements outlined in the referenced international standards (e.g., ISO, IEC, AAMI). For biocompatibility, it's the results of specific biological assays. For mechanical and electrical properties, it's measurement against defined limits.

8. The sample size for the training set

This is not applicable. The device is a physical medical device (breathing circuit), not a machine learning model. Therefore, there is no "training set" in the context of an AI/ML algorithm.

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

This is not applicable. As stated above, there is no training set for this device.
