The SIMEOX 200 airway clearance device is intended to promote airway clearance and to improve bronchial drainage by enhancing mobilization of bronchial secretions via high frequency oscillatory vibrations and intermittent negative pressure to the airway during exhalation. The device is intended to be prescribed for use in patients capable of independently generating cough.

SIMEOX 200 is intended for use in the home, hospital, and other healthcare institutions by individuals weighing at least 23 Kg.

The SIMEOX 200 Airway Clearance Device consists of a portable generator and a single patient use expiratory kit. The patient inhales from the ambient environment, naturally and independent of the device, and then exhales into the device mouthpiece. During the patient's exhalation, the SIMEOX 200 generates a pneumatic vibration throughout the airway. This vibration, applied at 6 Hz or 12 Hz via negative pressure pulses, disseminates throughout the bronchial tree in order to decrease mucus viscosity and increase secretion mobility. During or after therapy, the patient can clear the secretions by coughing independently.

This document describes the FDA's 510(k) clearance for the SIMEOX 200 Airway Clearance Device. It primarily focuses on demonstrating substantial equivalence to predicate devices through technical specifications and non-clinical performance testing.

The provided text does not contain information about acceptance criteria or a study proving the device meets those criteria in the context of human-in-the-loop performance, AI assistance, or expert-based ground truth establishment for diagnostic purposes.

The document states:

• "Performance verification testing was conducted on the bench with the SIMEOX 200 Airway Clearance Device to demonstrate the subject device performs to its pre-specified requirement specifications, which align with those of the predicate devices."
• "The SIMEOX 200 device also went through comprehensive software verification and validation testing to confirm the device operates within specification."
• "Testing demonstrated the SIMEOX 200 performed as intended and was safe and effective."
• "A human factors validation study was conducted with simulated first-time use of the product in adult users and dyads of children with caregivers. The study concluded that the device is safe for its intended users."

This indicates that the "acceptance criteria" and "study that proves the device meets the acceptance criteria" in this context refer to engineering and safety performance specifications, rather than clinical performance metrics typically associated with AI/diagnostic devices (like sensitivity, specificity, or reader improvement).

Therefore, I cannot populate the requested table and study details as they are not present in the provided text. The document describes a medical device (Airway Clearance Device), not an AI or diagnostic device that would typically involve the type of acceptance criteria and studies you've outlined.

The acceptance criteria implied are the device's ability to meet its pre-specified parameters (e.g., pressure range, oscillation frequencies) and demonstration of safety and effectiveness through bench testing, software validation, and human factors validation.

Here's a summary of the information that is available, reframing it in the context of device performance rather than AI/diagnostic performance:

The Inogen Rove 6 Portable Oxygen Concentrator provides a high concentration of supplemental oxygen to patients requiring respiratory therapy on a prescriptive basis. It may be used in the home, institution, and transport modalities. This device is to be used as an oxygen supplement and is not intended to be life sustaining or life supporting.

The Inogen Rove 6 Portable Oxygen Concentrator (Inogen Rove 6) is a Class 2, low risk, portable oxygen generator that provides a high concentration of supplemental oxygen to patients requiring respiratory therapy on a prescriptive basis. It may be used in home, institution, vehicle, and other transport modalities. It is used with a nasal cannula to channel oxygen from the device to the patient. The concentrator and the nasal cannula are non-sterile. The Inogen Rove 6 Portable Oxygen Concentrator is capable of continuous use in a home, institution, vehicle, and various mobile environments. Power options include 100 - 240 V-AC (50-60Hz) power supply, rechargeable battery packs, or a 13.5 -15.0 V-DC power cable. The Inogen Rove 6 Portable Oxygen Concentrator uses molecular sieve/pressure swing adsorption technology. Ambient air is drawn through particle filters by a compressor and forced through molecular sieve beds, which adsorb nitrogen and allow oxygen to pass. The airflow is then changed, and nitrogen is desorbed from the molecular sieve, allowing it to adsorb again during the next cycle. Oxygen is collected in an accumulator reservoir. Waste nitrogen is exhausted back into the room. A series of sieve beds, manifolds and precision valves, sensors and embedded software are used to control the cycle to make the system function. Oxygen is delivered to the patient on a pulse dose basis in precise amounts during the inhalation part of the breathing cycle. This conserver technology eliminates waste of unused oxygen at other times in the breathing cycle when it is not needed. The Inogen Rove 6 Portable Oxygen Concentrator senses the beginning of the inhalation cvcle and releases a specified dose of oxygen enriched gas from the accumulator reservoir, through a final filter, into the connected nasal cannula and on to the patient. The Inogen Rove 6 Portable Oxygen Concentrator utilizes Bluetooth technology that pairs the portable oxygen concentrator to a mobile device or tablet using the Inogen Connect App.

This is information extracted from a medical device 510(k) submission.

2. Sample Size Used for the Test Set and Data Provenance

The document does not explicitly state the sample size used for the test sets in non-clinical testing. It only mentions "Inogen performed testing to demonstrate and support safety and effectiveness when compared to the predicate and the applicable standards."

The data provenance is not specified regarding country of origin or whether it was retrospective or prospective. It refers to "Bench Testing" and "testing at a nationally registered test laboratory," implying laboratory-based testing rather than clinical data from human subjects.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

This information is not provided in the given document. The testing described is non-clinical bench testing and compliance with performance standards, which does not typically involve expert ground truth establishment in the same way clinical studies or image-based AI studies do.

4. Adjudication Method for the Test Set

This information is not applicable/provided. The document describes non-clinical bench testing against technical specifications and performance standards, not a study requiring adjudication of human-read results.

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/provided. The Inogen Rove 6 Portable Oxygen Concentrator is a hardware medical device (portable oxygen generator), not an AI-assisted diagnostic or interpretative tool. Therefore, an MRMC comparative effectiveness study involving human readers and AI assistance would not have been performed for this device.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

This information is not applicable/provided. As explained above, this device is not an AI algorithm. Its performance is evaluated through bench testing of its mechanical and electrical functions and oxygen delivery specifications. The device does contain "embedded software" (page 4), and "Software verification and validation" (page 19) was performed, indicating standalone testing of the software components. However, this is not an "algorithm only" study in the context of AI performance, but rather software testing for the device's operational control.

7. The Type of Ground Truth Used

For the non-clinical testing, the "ground truth" is defined by:

• Established Technical Specifications: Such as oxygen concentration levels (90% -3%/+6%), pulse volumes (± 15% of rated volume), pressure values, sound levels, etc.
• International Standards: Specifically, ISO 80601-2-69, ISO 80601-2-67, various parts of IEC 60601, and IEC 62366-1.
• Comparison to Predicate and Reference Devices: Demonstrating "substantial equivalence" to the performance and characteristics of previously cleared devices, particularly for aspects like oxygen delivery mode, purity, and flow.

This is primarily performance data and compliance with objective technical and regulatory standards, not expert consensus, pathology, or outcomes data in a clinical sense.

8. The Sample Size for the Training Set

This information is not applicable/provided. No AI model requiring a "training set" in the context of machine learning is described for this device. The software validation mentioned refers to verification of the device's embedded control software.

9. How the Ground Truth for the Training Set Was Established

This information is not applicable/provided, as no AI model with a training set is described.

The Inogen At Home Oxygen Concentrator is used on a prescriptive basis by patients requiring supplemental oxygen. It supplies a high concentration of oxygen and is used with a nasal cannula to channel oxygen from the concentrator to the patient. The Inogen At Home Oxygen Concentrator may be used in a home or institution.

The Inogen At Home is a stationary concentrator providing approximately 90% oxygen to patients on a continuous flow basis at a rate of 1.0 liter per minute (LPM) to 5.0 liters per minute (LPM), in 1.0 liter per minute (LPM) increments. Nasal cannula channels oxygen from device to patient; both concentrator and nasal cannula are non-sterile. The device is capable of continuous use in the home or in an institutional setting. The Inogen At Home can be powered by mains AC power found in the home or in an institutional setting. The Inogen At Home includes a detachable AC power cord to make the electrical connection to the AC mains. The Inogen At Home utilizes Pressure Swing Adsorption (PSA) technology to produce oxygen. Oxygen is separated from ambient air under pressure by molecular characteristics and affinity for adsorbent material. The molecular sieve preferentially adsorbs nitrogen, allowing enriched oxygen to collect in an accumulator; the process then swings to low pressure to desorb the nitrogen, exhausting it back into the environment. A series of sieve beds, manifold with precision valves, sensors, and embedded software are used collectively to govern system functionality.

The provided document describes the Inogen At Home Oxygen Concentrator, a medical device for supplemental oxygen delivery. It includes details about its purpose, technological characteristics, and conformance to relevant standards. However, the document does not contain a study that validates the device against specific acceptance criteria in the format requested.

Here's an analysis based on the information provided in the document, highlighting what is missing for a complete answer to your request:

The document clearly states the device's conformance to several international and national standards (EN ISO 8359:2012, ASTM F 1464:2005, IEC 60601-1). It also lists "performance testing" that was done, but does not provide specific acceptance criteria for these tests or the reported performance data in a quantitative table.

Here's a breakdown of what can and cannot be answered based solely on the provided text:

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

• Acceptance Criteria Mentioned (Implicitly by conformance to standards or general tests):

  • Oxygen Concentration: Approximately 90% (This is a design spec, not explicitly an "acceptance criterion" from a study).
  • Flow Rate: 1.0 to 5.0 LPM in 1.0 LPM increments (Design spec).
  • Electrical Safety/Compatibility: Conformance to IEC 60601-1.
  • Software Functionality: Tested.
  • Fire Mitigation: Tested.
  • Noise, Temperature, and Altitude Ranges: Tested.

  • Overall safety requirements per EN ISO 8359:2012 and ASTM F 1464:2005.

• Reported Device Performance: The document states that "Performance testing included the assessment of electrical safety/ compatibility, software functionality, fire mitigation and noise, temperature and altitude ranges, outlet pressure, flow indicator accuracy, and oxygen concentration." It also mentions "Biocompatibility testing included the evaluation of particulate matter, Ozone, Volatile Organic Compounds, Carbon Dioxide, and Carbon Monoxide." However, no specific quantitative results or performance data against numerical acceptance criteria are provided in the text. For example, it doesn't say "oxygen concentration met specific criteria of X% +/- Y%" or "noise levels were Z dB below threshold."

Therefore, a table cannot be fully constructed with specific quantitative acceptance criteria or reported performance from this document.

Regarding the study that proves the device meets the acceptance criteria:

The document describes "Non-clinical Performance Data" and "Performance testing" as well as "Biocompatibility testing." These are the studies mentioned. However, the details required for points 2-9 are not present in the provided text.

Missing Information:

• 2. Sample sized used for the test set and the data provenance: Not mentioned.
• 3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable for this type of device testing. "Ground truth" in this context would be objective measurements from calibrated equipment, not expert consensus interpretation.
• 4. Adjudication method for the test set: Not applicable.
• 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.
• 6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable. This is a physical oxygen concentrator, not an algorithm.
• 7. The type of ground truth used: For performance tests, the ground truth would be objective measurements from calibrated sensors and analytical equipment (e.g., oxygen analyzers, flow meters, pressure gauges, sound level meters, gas chromatographs for impurities). For biocompatibility, it would be analytical results against established safe limits. This is implied by the testing, but not explicitly detailed.
• 8. The sample size for the training set: Not applicable. This is a hardware device, not an AI algorithm requiring a training set.
• 9. How the ground truth for the training set was established: Not applicable.

Summary:

The provided text serves as a 510(k) summary for a medical device (oxygen concentrator). It broadly discusses performance and biocompatibility testing and conformance to standards to demonstrate "substantial equivalence" to predicate devices. However, it does not detail a specific quantitative study with acceptance criteria and results in the manner typically expected for AI/diagnostic devices as implied by your questions, which are more tailored to software-based systems or image analysis. The "acceptance criteria" here are largely defined by compliance with the cited medical device standards (EN ISO 8359, ASTM F 1464, IEC 60601-1) and internal design specifications.
