    AI/ML Overview

    The provided text describes a 510(k) submission for the Chad Therapeutics Bonsai Model 800, which is a modified oxygen conserver. However, the document does not contain an acceptance criteria table or a study report detailing specific performance metrics against acceptance criteria. Instead, it focuses on demonstrating substantial equivalence to a predicate device through general statements about design verification and validation activities.

    Therefore, many of the requested sections below cannot be populated from the provided text.

    Here's an attempt to answer the questions based on the available information:

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

    The document states that "The Bonsai passed all of the test criteria established in the Bonsai design verification and validation tests." However, it does not provide a table with specific acceptance criteria or the reported performance data for each criterion. It only mentions one specific safety test the regulator passed.

    Acceptance Criteria (Not Explicitly Stated)Reported Device Performance
    (Specific performance metrics relating to flow rate accuracy, pressure regulation, oxygen delivery consistency, battery life, safety features, etc. are not provided.)"The Bonsai passed all of the test criteria established in the Bonsai design verification and validation tests."
    Compliance with ASTM G 175-03 for Regulator Sensitivity and Fault Tolerance"The regulator in the device passed the ASTM G 175-03 Standard Test Method for Sensitivity and Fault Tolerance of Oxygen Regulators Used for Medical and Emergency Applications safety test."

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

    This information is not provided in the document. The document only generally states "All risk assessment, design verification and validation activities were conducted in accordance with approved product requirements to demonstrate that the Chad Therapeutics Bonsai would perform as intended."

    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 applicable as this device is an oxygen conserver and the document describes engineering verification and validation, not studies requiring expert visual assessment or ground truth establishment in a medical imaging or diagnostic context.

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

    This information is not applicable for the type of device and testing 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

    This information is not applicable as this device is an oxygen conserver and does not involve human readers interpreting images or data with or without AI assistance.

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

    This information is not applicable as this is a mechanical medical device, not an algorithm or AI system.

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

    For this type of device (oxygen conserver), "ground truth" would generally refer to established engineering standards, specifications, and physical measurements. The document implies that the "ground truth" for the tests involved verifying the device's performance against predefined "product requirements" and industry standards like ASTM G 175-03.

    8. The sample size for the training set

    This information is not applicable as this is a mechanical medical device, not an algorithm or AI system that requires a "training set."

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

    This information is not applicable for the same reason as above.

    Intended Use

    The Chad Therapeutics Lotus (modified Chad Therapeutics OXYMATIC Model 411) is intended for use in the same manner as the unmodified device, i.e., for prescription use only, to be used as a portable oxygen delivery system for patients who require supplemental oxygen at flow rates equivalent to 1 to 6 liters per minute, in their home and for ambulatory use.

    Device Description

    The Chad Therapeutics Lotus is a microprocessor-controlled device, which is a combination of a low-pressure regulator and an oxygen conserver, designed for use with a compressed oxygen source to provide a pulse of oxygen that is equivalent to 1 to 6 liters per minute, depending on the flow rate setting.

    AI/ML Overview

    This document is a 510(k) premarket notification for a medical device modification, not a study report. Therefore, it does not contain the detailed information typically found in a study proving a device meets acceptance criteria. A 510(k) submission, especially a "Special 510(k)," primarily focuses on demonstrating substantial equivalence to a predicate device rather than conducting a full-scale clinical trial to prove efficacy against acceptance criteria.

    However, I can extract the information that is present and explain why certain information is not available in this type of document.

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

    Acceptance CriteriaReported Device Performance
    Safety: Device operates safelyMet: - The regulator in the device passed the ASTM PS 127-00 Promoted Ignition Safety Test. - Electromagnetic Compatibility, Electrostatic Discharge, Immunity, Magnetic Fields Immunity, Magnetic Fields Emissions, Quasi-Static Electric Fields, Radiated and Conducted Field Emissions, etc., were conducted in accordance with the FDA Reviewer Guidance for Premarket Submissions, Anesthesiology and Respiratory Devices Branch, Division of Cardiovascular, Respiratory and Neurological Devices Document and applicable EN 60601 Medical Electrical Equipment specifications. - The software complies with applicable standards per FDA Reviewers and content of premarket submissions for software contained in medical devices.
    Functionality: Device performs as intended (delivering oxygen equivalent to 1 to 6 liters per minute)Met (by substantial equivalence): The document states that "All risk assessment, design verification and validation activities were conducted in accordance with device requirements to demonstrate that the Chad Therapeutics Lotus would perform as intended." It also claims that the modified device "has the same technological characteristics" and "the software and the patient inhalation detection sensor portion of the device are identical to the predicate device." While specific performance metrics against an explicit numerical acceptance criterion are not provided, the conclusion of "substantial equivalence" implies that its performance is considered equivalent to the predicate device, which was already cleared for this function.

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

    This information is not provided in this 510(k) submission. The testing described (ASTM, EMC, software compliance) involves engineering and bench testing, not typically a "test set" in the context of human data. There's no human subject data mentioned, so concepts like country of origin, retrospective/prospective, or sample size are not applicable here.

    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 applicable/provided. The testing performed is primarily technical and regulatory compliance (e.g., engineering standards, software standards). There is no mention of "ground truth" being established by medical experts for a diagnostic or interpretative purpose.

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

    This information is not applicable. Adjudication methods are typically used in clinical studies where multiple human readers or experts are involved in interpreting data (e.g., radiology images). The tests described are bench tests and engineering compliance checks.

    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

    There was no MRMC comparative effectiveness study done. This is a special 510(k) for a device modification (oxygen conserver), and it does not involve AI or human interpretation of cases. The document focuses on demonstrating physical and software modifications maintain safety and effectiveness equivalent to the predicate device.

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

    This is not applicable. The device is an oxygen conserver, a physical medical device, not an algorithm or AI system.

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

    The "ground truth" in this context is based on engineering standards, safety standards (e.g., ASTM PS 127-00), and regulatory compliance specifications (e.g., EN 60601 for EMC, FDA guidance for software). These standards define the acceptable performance characteristics and safety profiles for the device. There's no biological or clinical "ground truth" derived from patient data mentioned.

    8. The sample size for the training set

    This is not applicable. The device is a hardware product with software; it is not a machine learning model that requires a "training set" of data in the AI sense.

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

    This is not applicable for the same reason as point 8.

    Intended Use

    The Chad Therapeutics Sage is intended for prescription use only, to be used as part of a portable therapeutic oxygen system for patients that require supplemental oxygen while at rest or during activity.

    Device Description

    The Chad Therapeutics Sage is a microprocessor-controlled device, which is a combination of a low-pressure regulator and a therapeutic oxygen device, designed for use with ambulatory oxygen systems. It delivers boluses of oxygen that is equivalent to 1 to 6 liters per minute, depending on the flow rate setting and whether the user is at rest or active.

    AI/ML Overview

    The provided 510(k) submission for the Chad Therapeutics Sage does not provide detailed acceptance criteria or a specific study proving the device meets acceptance criteria in the manner typically expected for AI/ML-based medical devices.

    Instead, this submission is for a physical medical device (a non-continuous ventilator/oxygen conserver) and its acceptance criteria and "studies" are focused on demonstrating substantial equivalence to predicate devices through various types of engineering and performance testing.

    Here's a breakdown of the information that can be extracted, and where the requested AI/ML specific information is not applicable or not provided in this type of submission:


    Acceptance Criteria and Device Performance (Based on the document):

    The document does not list specific numerical acceptance criteria (e.g., sensitivity, specificity, accuracy targets) as would be the case for an AI/ML algorithm. Instead, the "acceptance criteria" are implied by demonstrating that the device performs as intended and is substantially equivalent to predicate devices.

    Acceptance Criteria (Implied)Reported Device Performance
    Functional Equivalence: Delivers oxygen boluses equivalent to 1-6 LPM (at rest/activity).The device is a "microprocessor-controlled device... designed for use with ambulatory oxygen systems. It delivers boluses of oxygen that is equivalent to 1 to 6 liters per minute, depending on the flow rate setting and whether the user is at rest or active." This is the core functionality description, implying it meets this range successfully.
    Safety and Effectiveness: Performed as intended and is safe and effective."Performance, mechanical, electrical, electromagnetic compatibility, magnetic fields immunity, magnetic fields emissions, quasi-static electric fields and environmental testing was conducted to demonstrate that the Sage would perform as intended." "Based on the above, we concluded that the Chad Therapeutics Sage is substantially equivalent to legally marketed predicate devices and is safe and effective for its intended use."
    Technological Equivalence: Incorporates a motion sensor for automatic mode switching."The Sage has both a rest and activity setting and incorporates a motion sensor to detect user activity to switch the device automatically from an at rest to an active flow setting." (This is a differentiating feature, implying it functions as designed.)

    Since this is a submission for a physical device, not an AI/ML algorithm, most of the specific questions regarding test sets, ground truth, experts, and AI-specific studies are not applicable (N/A) for this document.

    Detailed Breakdown of Requested Information:

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

      • See table above. The acceptance criteria are inferred from the device description and the claim of substantial equivalence, as specific performance metrics like sensitivity/specificity are not relevant for this type of device.
    2. Sample size used for the test set and the data provenance:

      • N/A. This device does not use a "test set" in the context of AI/ML data. The "testing" involved engineering and performance verification of the physical product, likely involving a limited number of physical prototypes or production units, not a dataset of patient information. The document does not specify the number of units tested.
    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

      • N/A. Ground truth in the AI/ML sense (e.g., expert-labeled images) is not applicable here. The "ground truth" for a physical device is its adherence to engineering specifications and performance standards, verified through objective measurements and physical tests.
    4. Adjudication method (e.g., 2+1, 3+1, none) for the test set:

      • N/A. Not relevant.
    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:

      • N/A. This is a physical oxygen delivery device, not a diagnostic or AI-assisted interpretation tool. MRMC studies are not applicable.
    6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

      • N/A. There is no standalone algorithm being evaluated in this submission. The device is a physical product.
    7. The type of ground truth used (expert consensus, pathology, outcomes data, etc):

      • The "ground truth" for this device's performance would be derived from objective engineering measurements, calibration standards, and validated test methods (e.g., precise oxygen flow meters, pressure gauges, electrical safety testers). These are not typically described as "ground truth" in regulatory summaries for physical devices.
    8. The sample size for the training set:

      • N/A. This is not an AI/ML device; there is no "training set." The microprocessor controls are programmed based on engineering design and performance requirements.
    9. How the ground truth for the training set was established:

      • N/A. Not applicable.

    In summary: The provided 510(k) is for a hardware medical device (an oxygen conserver). The acceptance criteria are implicitly met by demonstrating that the device functions as described, meets safety standards, and is substantially equivalent to existing predicate devices. The "studies" involve various engineering, electrical, mechanical, and environmental tests, rather than clinical studies or AI/ML performance evaluations with specific datasets and ground truth.

    Intended Use

    The Chad Therapeutics OXYPNEUMATIC CYPRESS Model 511 is intended for prescription use only, to be used as part of a portable oxygen delivery system for patients that require supplemental oxygen in their home and for ambulatory use.

    Device Description

    The Chad Therapeutics OXYPNEUMATIC CYPRESS Model 511 is a pneumaticcontrolled device, which is a combination of a low-pressure regulator and an oxygen conserver, designed for use with ambulatory oxygen systems. It delivers boluses of oxygen that is equivalent to 1 to 6 liters per minute, depending on the flow rate setting.

    AI/ML Overview

    This document refers to a 510(k) premarket notification for a medical device called the "Chad Therapeutics OXYPNEUMATIC CYPRESS Model 511," an oxygen conserver. The information provided is for regulatory clearance based on substantial equivalence, not a study proving the device meets specific acceptance criteria in terms of clinical performance or diagnostic accuracy.

    Therefore, many of the requested elements for describing "acceptance criteria and the study that proves the device meets the acceptance criteria" are not applicable or cannot be extracted from the provided text. This document is focused on regulatory clearance and substantial equivalence to predicate devices, not a clinical performance study with specific acceptance criteria as one might expect for a diagnostic or AI-driven device.

    Here's an attempt to answer the questions based only on the provided text, highlighting what is missing or not applicable:

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

    The document does not specify quantitative "acceptance criteria" in the way one might for diagnostic accuracy (e.g., sensitivity, specificity, AUC thresholds). Instead, it relies on "substantial equivalence" to predicate devices and general performance, mechanical, and environmental testing.

    Acceptance Criteria (Implied)Reported Device Performance
    Performs as intended (delivers boluses of oxygen equivalent to 1-6 LPM)"Performance, mechanical and environmental testing was conducted to demonstrate that the OXYPNEUMATIC CYPRESS Model 511 would perform as intended." (No specific metrics or thresholds provided.)
    Safe and effective for intended use (as an oxygen conserver)"Based on the above, we concluded that the Chad Therapeutics OXYPNEUMATIC CYPRESS Model 511 is substantially equivalent to legally marketed predicate devices and is safe and effective for its intended use."
    Substantially equivalent to predicate devices"The OXYPNEUMATIC CYPRESS Model 511 has the same technological characteristics as the predicate devices." (Predicate devices listed: Victor Medical Products O2n Demand II (K992659), Western Medica OPC Oxygen Conserving Device (K010747), Precision Medical PM 1800 Conserving Device (K001412)).

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

    This information is not provided in the document. The document mentions "Performance, mechanical and environmental testing" but does not detail the methodology, sample sizes, or data provenance for these tests. This is not a clinical study in the sense of a test set with patient data.

    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 applicable as this is not a study establishing a diagnostic ground truth or involving expert review of a test set for clinical performance. The evaluation is based on engineering and performance testing for regulatory clearance.

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

    This information is not applicable as this is not a study requiring adjudication of expert opinions for a test set.

    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 information is not applicable. This device is an oxygen conserver, not an AI-assisted diagnostic tool or an imaging device requiring human reader interpretation. No MRMC study was conducted or is relevant to this type of device.

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

    This information is not applicable. This is a physical medical device (oxygen conserver), not an algorithm or AI system.

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

    For the "testing" mentioned, the "ground truth" would be related to the device's technical specifications and intended function (e.g., ability to accurately deliver oxygen boluses at specified rates, durability under environmental conditions, safety criteria). However, the document does not specify the exact types of ground truth used for "Performance, mechanical and environmental testing." It likely refers to established engineering standards and specifications for oxygen delivery devices.

    8. The sample size for the training set

    This information is not applicable. This is not an AI/ML device that requires a training set.

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

    This information is not applicable. This is not an AI/ML device that requires a training set.

    Intended Use

    The intended use of the Chad Total O2 Delivery System is to supply low-pressure supply pressurized oxygen to fill oxygen cylinders for patient's ambulatory use. The oxygen supplied by the Total O2 Delivery System is supplemental and is not life supporting and not intended to be used with or for any life support applications or in the presence of flammable anesthetics.

    The modified Chad Total O2™ Delivery System is intended for use in the same manner as the unmodified device: The Total O2™ Delivery System is indicated for Supplemental Medical Oxygen for treatment of Respiratory Diseases.

    Device Description

    The Chad Total O2 Delivery System addresses several needs of patients and homecare providers. The Total O2 Delivery System has been designed to reduce the need for built storage and transport of liquid oxygen as well as the storage and transport of high-pressure oxygen gas cylinders for ambulatory use. The Total O2 Delivery System is comprised of conventional procedures and/or an integral pressure intensifier which supplies low pressure oxygen to a nasal cannula and/or an integral proposition of the oxygen gas cylinder for ambulatory use. The Total O2 Delivery System has a unique cylinder fill mechanism, which allows it to be easily, and safely connect to the patient's Total O2 oxygen cylinder. The unique cylinder fill mechanism ensures that Total O2 oxygen cylinders can only be filled by the Total O2 Delivery System. The Total O2 oxygen cylinders will be offered in two versions: 1. The original Total O2 cylinders with built in pressure reducer. 2. The Total O2 Post Valve cylinders with the same unique fill port as the original The Total O2, no built in pressure reducer but with a unique post valve outlet. The Total O2 post valve incorporates an internal mechanism to prevent filling the cylinders through the unique post valve port. Furthermore the Total O2 post valve would incorporate an index pin in the CGA V-1 number 13 position to prevent CGA-870 accordators, conserving devices, etc. from attaching to the unique post valve.

Special 510(k)s are typically used for modifications to a manufacturer's own legally marketed device where the modification does not affect the device's indications for use or its fundamental scientific technology. Therefore, the information provided focuses on demonstrating substantial equivalence to the predicate device rather than presenting a full de novo study with extensive performance metrics against a predefined set of acceptance criteria.

    Based on the provided text, the document states:

    "Performance, mechanical, electrical, electromagnetic compatibility and r onomance, moshal testing was conducted to demonstrate that the Chad Total O₂ Delivery System would perform as intended."

    However, there are no specific acceptance criteria or detailed results of these tests provided in the document. The rationale for substantial equivalence primarily relies on the device having the "same technological characteristics" and the "hardware portion of the device is identical to the predicate device" with only modifications to the cylinder adapters and a unique post valve outlet for new cylinder types.

    Since specific acceptance criteria and detailed study results are not present, much of the requested information cannot be extracted from this document.

    Here's what can be inferred or explicitly stated from the provided text:

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

    • Acceptance Criteria: Not explicitly stated in the document. For a Special 510(k), acceptance is typically based on demonstrating that the modifications do not alter the safety or effectiveness compared to the predicate device, often through bench testing validating specific changes.
    • Reported Device Performance: The document only generically states that "Performance, mechanical, electrical, electromagnetic compatibility and r onomance, moshal (sic) testing was conducted to demonstrate that the Chad Total O₂ Delivery System would perform as intended." No specific performance metrics (e.g., flow rates, oxygen concentration, battery life, fill times, pressure retention) or their values are provided.

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

    • Sample Size: Not specified. The testing mentioned appears to be bench testing on the device prototypes, not a clinical trial with human subjects.
    • Data Provenance: Not specified, but implied to be internal testing conducted by Chad Therapeutics, Inc. (the manufacturer).

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

    • Not applicable. This device is a modified oxygen delivery system, and the testing described is technical/engineering performance testing, not a diagnostic or AI-driven system that requires expert ground truth for interpretation.

    4. Adjudication method for the test set:

    • Not applicable. As above, this type of testing (mechanical, electrical, performance) does not typically involve adjudication by experts in the way clinical diagnostic studies do.

    5. If a multi-reader, multi-case (MRMC) comparative effectiveness study was done, and its effect size:

    • No. An MRMC study is not mentioned as this is not a diagnostic imaging device or an AI-assisted interpretation system requiring human reader comparison.

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

    • Not applicable. This is a physical oxygen delivery device, not an algorithm.

    7. The type of ground truth used:

    • Not explicitly stated/applicable for this context. For mechanical and electrical performance, the "ground truth" would be engineering specifications and established standards for oxygen delivery systems. The document states testing was done to ensure the device "would perform as intended," implying comparison against these internal specifications and safety standards for the device type.

    8. The sample size for the training set:

    • Not applicable. This device does not involve a "training set" in the context of machine learning.

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

    • Not applicable. This device does not involve a "training set" in the context of machine learning.

    In summary, the provided document is a regulatory submission for a device modification, focusing on demonstrating equivalence to an existing predicate device rather than detailing a comprehensive new product validation study with specific acceptance criteria and performance data. The "Summary of Testing" section is very brief and high-level, indicating only that various types of engineering tests were conducted without providing any specific results or acceptance thresholds.
