The Model 300157 CPAP System is a single patient reusable device. The Model 300157 CPAP System provides continuous positive airway pressure (CPAP) to support treatment of adults (over 30 kg) with Obstructive Sleep Apnea.

The CPAP System provides a continuous positive airway pressure (CPAP) to support treatment of obstructive sleep apnea. When interfaced with a CPAP Mask or CPAP Patient Interface the CPAP System provides a constant pressure of 4 to 20 cmHzO above the ambient atmospheric pressure to patient's nasal airway. This constant pressure, when set to a therapeutic level as prescribed by a physician, supports retaining an open airway during sleep. The CPAP System has primary components: 1) CPAP main unit, 2) Removable headgear, 3) External power supply/optional mobile power adaptor, and 4) Patient Interface.

This document is a 510(k) summary for a CPAP system, not a study report. Therefore, it does not contain the detailed information requested regarding acceptance criteria and a study that proves the device meets those criteria.

A 510(k) submission primarily demonstrates "substantial equivalence" to a predicate device, which often relies on performance testing to show that the new device performs as safely and effectively as the predicate. However, the provided text only states that "Laboratory and standards compliance were provided to support the CPAP System performance," without detailing what those specific tests were, what the acceptance criteria for those tests were, or the results of those tests.

Therefore, I cannot provide most of the requested information based on the input text.

Here's what can be extracted and what cannot:

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

• Cannot be provided. The document does not define specific acceptance criteria (e.g., pressure accuracy, flow rates, noise levels) or report specific performance metrics against such criteria. It only generally states "Laboratory and standards compliance were provided to support the CPAP System performance."

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

• Cannot be provided. No information about sample sizes for any test set or data provenance is mentioned.

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):

• Cannot be provided. This type of information is relevant for studies involving human interpretation (e.g., medical imaging AI), which is not the nature of this device or document. The CPAP system's performance would primarily be evaluated through engineering and clinical performance tests, not ground truth established by experts in a diagnostic context.

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

• Cannot be provided. Not applicable to this type of device submission.

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:

• Cannot be provided. Not applicable to a standalone CPAP device. MRMC studies are typically for AI-assisted diagnostic tools.

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

• While the device itself is "standalone" in its operation, the document doesn't detail performance studies. It states "Laboratory and standards compliance were provided," implying technical performance testing rather than a specific "standalone study" report in the context of an algorithm. However, its intended function is continuous positive airway pressure delivery, which is an "algorithm only" type of function in terms of consistent pressure delivery. No performance data is given.

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

• Cannot be provided. The concept of "ground truth" as typically used in this context (e.g., for AI model training or evaluation in diagnostics) is not directly applicable here. Performance would be assessed against established engineering standards and clinical efficacy, not an expert-derived ground truth.

8. The sample size for the training set:

• Cannot be provided. This device is a hardware system, not typically an AI/ML algorithm that requires a "training set" in the conventional sense. Its design and manufacturing would adhere to engineering principles and standards.

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

• Cannot be provided. See point 8.

In summary, the provided text is a regulatory summary (510(k)) for a medical device and not a detailed study report. It focuses on the device's description, intended use, technology, and claim of substantial equivalence, rather than providing the granular data from performance studies.

The aura CPAP System provides continuous positive airway pressure (CPAP) to support treatment of adults (over 30kg) with Obstructive Sleep Apnea.

The aura CPAP System provides a continuous positive airway pressure (CPAP) to support treatment of obstructive sleep apnea. During obstructive sleep apnea, the airway collapses. When interfaced with a CPAP Mask or CPAP Patient Interface the aura CPAP System provides a constant pressure of 4 to 20 cmH2O above the ambient atmospheric pressure to patient's nasal airway. This constant pressure supports retaining an open airway during sleep.

The aura CPAP System has four significant components:

• 1. CPAP Blower,
• 2. Optional Humidifier,
• 3. Optional Battery Pack, and
• 4. Patient Interface.

The provided document describes the AEIOMed aura CPAP System, a device intended for the treatment of obstructive sleep apnea. However, it does not contain detailed information about specific acceptance criteria or a study that rigorously proves the device meets those criteria in the way typically expected for a detailed scientific or clinical study.

Instead, the document is a 510(k) premarket notification summary, which focuses on demonstrating substantial equivalence to existing legally marketed predicate devices. The "Summary of Safety and Effectiveness" section and the FDA letter confirm this.

Therefore, many of the requested data points (like sample size for test sets, number of experts for ground truth, MRMC studies, standalone performance, detailed ground truth methods, training set details) are not available in this specific document, as those are generally associated with more extensive clinical trials or performance studies that were likely not required for a 510(k) submission based on substantial equivalence and laboratory testing.

Here's what can be extracted and what is missing:

1. Table of Acceptance Criteria and Reported Device Performance

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

• Not explicitly stated/Provided. The document refers to "Laboratory and standards compliance" but does not detail a clinical test set with human subjects. The evaluation for 510(k) substantial equivalence often relies on bench testing, electrical safety, and biocompatibility rather than extensive clinical studies if the technology is well-established and has predicate devices.
• Data Provenance: Not specified, but given it's a US company seeking FDA clearance, any supporting data would likely adhere to US regulatory standards.

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

• Not applicable/Provided. This type of detail is absent because the submission focuses on substantial equivalence and laboratory testing, not a clinical study requiring expert ground truth for interpretation of outcomes.

4. Adjudication method for the test set

• Not applicable/Provided. No clinical test set with adjudicated outcomes is described.

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. This is not an AI-assisted device. It's a medical device (CPAP system) for delivering continuous positive airway pressure. Therefore, an MRMC study related to AI assistance is irrelevant.

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

• Not applicable. This question pertains to algorithmic performance, which is not relevant to a mechanical CPAP device.

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

• Not applicable. For this type of device and submission, the "ground truth" would be related to engineering specifications, safety standards, and performance characteristics demonstrated through bench testing, rather than clinical outcomes or diagnoses. The device's ability to maintain a prescribed pressure and operate safely and effectively as designed would be the focus.

8. The sample size for the training set

• Not applicable/Provided. There is no indication of a "training set" in the context of machine learning or AI, as this is a mechanical medical device.

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

• Not applicable/Provided. As above, no training set or machine learning components are mentioned.

In summary: The document is a 510(k) clearance summary, which primarily aims to demonstrate substantial equivalence to existing devices through appropriate testing (likely bench testing and compliance with relevant standards) rather than extensive de novo clinical trials with human subjects and expert adjudication of outcomes. Therefore, much of the requested information related to clinical study design and performance metrics against specific, numerically defined acceptance criteria is not present here. The main "acceptance criterion" presented is substantial equivalence, which the FDA concurred with.
