    Intended Use

    The AVEA is intended to provide continuous respiratory support in an institutional health care environment (e.g. hospitals). It may be used on neonatal through adult patients. It should only be operated by properly trained clinical personnel, under the direction of a physician.

    Device Description

    The AVEA is a servo-controlled, software-driven ventilator. It has a dynamic range of breathing gas delivery that provides for neonatal through adult patients. Its graphical user interface module (UIM) has a flat panel color LCD with real time charting and digital monitoring capabilities, a touch screen for interaction, membrane kevs and a dial for changing settings and operating parameters. It also has an internal gas delivery system with servo controlled active inhalation and exhalation functions. Using internal batteries this provides inter-hospital transport as well as back up capability due to loss of AC power. The AVEA may be configured as a conventional ventilator or non-invasive positive pressure ventilator (NPPV). It has been designed to function using commonly available accessories.

    AI/ML Overview

    The provided document is a 510(k) summary for the AVEA Ventilator, focusing on modifications for Volume Guarantee and Nasal Intermittent Positive Pressure Ventilation. It states that "Performance testing verified that the AVEA Ventilator meets its performance requirements and that this device is substantially equivalent to medical devices currently legally marketed in the United States." However, it does not provide specific details about the acceptance criteria or the study that proves the device meets those criteria, as requested in the prompt.

    Therefore, I cannot provide a complete answer to your request based on the provided text. The document confirms that performance testing was done, but it omits the actual results and methodology of that testing.

    Here's what I can extract and what is missing based on your request:

    1. Table of acceptance criteria and the reported device performance:

    • Missing from the document. The document states that performance testing "verified that the AVEA Ventilator meets its performance requirements," but it does not list these requirements (i.e., acceptance criteria) or the specific reported device performance against them.

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

    • Missing from the document. The document mentions "Performance testing" but does not specify the sample size, data provenance, or whether it was retrospective or prospective.

    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 / Missing from the document. This type of information is typically relevant for AI/ML-based diagnostic devices where a "ground truth" needs to be established, often by human experts reviewing medical images or patient data. The AVEA Ventilator is a mechanical ventilator, and its performance testing would likely involve engineering and physiological measurements rather than expert review for "ground truth." Therefore, this information is not relevant in the context of this device or is completely absent.

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

    • Not applicable / Missing from the document. Similar to point 3, adjudication methods are usually for resolving discrepancies in expert interpretations, which is not relevant for a mechanical ventilator's performance testing.

    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 / Missing from the document. An MRMC study is relevant for diagnostic AI tools involving human readers. This is not applicable to a mechanical ventilator like the AVEA Ventilator.

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

    • Not applicable / Missing from the document. This question is also focused on AI/ML algorithms. The AVEA Ventilator has software that implements Volume Guarantee and Nasal Intermittent Mandatory Ventilation, which are automated functions. The document states "software implement Volume Guarantee which is the automated requlation of inspiratory pressure," implying standalone algorithmic function within the device. However, the performance study details for these automated functions are not provided.

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

    • Not applicable / Missing from the document. As mentioned in point 3, the concept of "ground truth" in the context of expert review is unlikely to apply to the performance testing of a mechanical ventilator. The ground truth for such a device would typically be derived from engineering specifications, established physiological parameters, and direct measurement against those standards. The specific methods are not detailed.

    8. The sample size for the training set:

    • Not applicable / Missing from the document. A "training set" typically refers to data used to train an AI/ML model. While the ventilator has "software-driven" functions, the document does not suggest an AI/ML model that would require a distinct training set in the conventional sense. The "training" would be more akin to software development and verification/validation against specifications.

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

    • Not applicable / Missing from the document. For the reasons stated in points 7 and 8, this information is not provided and likely not relevant in the AI/ML context.

    Intended Use

    The AVEA is intended to provide continuous respiratory support in an institutional health care environment (e.g. hospitals). It may be used on adult, pediatric, and neonatal patients. It should only be operated by properly trained clinical personnel, under the direction of a physician.

    Device Description

    The AVEA is a servo-controlled, software-driven ventilator. It has a dynamic range of breathing gas delivery that provides for neonatal through adult patients. Its graphical user interface module (UIM) has a flat panel color LCD with real time charting and digital monitoring capabilities, a touch screen for interaction, membrane keys and a dial for changing settings and operating parameters. It also has an internal gas delivery system with servo controlled active inhalation and exhalation functions. Using internal batteries this provides inter-hospital transport as well as back up capability due to loss of AC power. The AVEA may be configured as a conventional ventilator or non-invasive positive pressure ventilator (NPPV). It has been designed to function using commonly available accessories.

    AI/ML Overview

    This is a 510(k) premarket notification for a medical device (AVEA Ventilator), not a study report. Therefore, much of the requested information regarding acceptance criteria and study details for device performance, ground truth, and expert evaluation is not available in the provided text.

    However, based on the submission, here's what can be extracted and inferred:

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

    The document does not explicitly state quantitative acceptance criteria or detailed reported device performance in a table format. It states generally that: "Performance testing verified that the AVEA Ventilator meets it's performance requirements and that this device is substantially equivalent to medical devices currently legally marketed in the United States."

    The focus of this 510(k) is on modifications to an already cleared device, asserting substantial equivalence. The specific modifications are:

    • "Software update encompasses a modification to the current . Non-Invasive ventilation previously cleared under K013642 of which allows for a particular mode on the Infant Flow Plus, Nasal CPAP."
    • "This Nasal CPAP mode that is emulated is accomplished by a software modification only, utilizing existing AVEA hardware."
    • "This Nasal CPAP mode is only for single level continuous positive airway pressure to nasal pronos."

    Therefore, the "acceptance criteria" for this specific submission would implicitly be:

    • The modified AVEA Ventilator, with the new Nasal CPAP software, performs equivalently to the predicate devices for continuous ventilation and specifically for the Nasal CPAP mode.
    • The software modification does not adversely affect existing validated functionalities.

    Given the nature of a ventilator, performance metrics would likely revolve around aspects such as:

    • Accuracy of delivered pressure/volume/flow.
    • Response time to patient effort.
    • Safety alarms and limits.
    • Biocompatibility (not directly covered by the software modification but generally a part of medical device approval).

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

    The document does not provide details on the sample size for any specific test set, nor the data provenance (country of origin, retrospective/prospective). The submission refers to "Performance testing" in a general sense.

    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)

    This information is not provided. Since this is an engineering performance assertion for a ventilator and not a diagnostic device relying on expert interpretation of images or signals, the concept of "ground truth" derived from expert consensus in that context is unlikely to apply directly in the same way. Performance testing for a ventilator typically involves engineering and physiological measurements rather than expert clinical consensus on data.

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

    Not applicable/not provided. Adjudication methods like 2+1 or 3+1 are typically used in studies involving expert interpretation where disagreements need to be resolved for ground truth establishment. This is not the type of study 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

    Not applicable. This is a ventilator device, not an AI-assisted diagnostic tool for human readers.

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

    This concept doesn't directly apply as the AVEA Ventilator is a device that interacts with a patient and is operated by trained clinical personnel. The "performance testing" mentioned would be for the device's functionality, which by its nature is "standalone" in terms of its mechanical and software operation, but in a real-world scenario, it's always "with human-in-the-loop" for patient management. The document states it is "servo-controlled, software-driven."

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

    Given the device type, "ground truth" would likely be derived from:

    • Engineering specifications and validated measurement equipment (e.g., flow sensors, pressure transducers) for evaluating the ventilator's physical outputs.
    • Physiological models or test lung systems to simulate patient conditions.
    • Compliance with recognized standards (e.g., ISO standards for ventilators).
      However, the specific methods are not detailed in the provided text.

    8. The sample size for the training set

    Not applicable. This device is not described as utilizing a machine learning model that requires a distinct "training set" in the context of AI/ML. The software modification is likely a rule-based or control-algorithm update, not an autonomously learning system.

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

    Not applicable, as there is no mention of a machine learning training set.
