The provided FDA 510(k) clearance letter is for a Portable Oxygen Concentrator. This device is not an AI/ML-enabled device. The information requested in the prompt (acceptance criteria, study details, sample size, ground truth, expert adjudication, MRMC studies, etc.) is typically associated with the rigorous evaluation of AI/ML software as a medical device (SaMD) or AI-enabled medical devices, especially those using diagnostic imaging.
Medical devices like portable oxygen concentrators are evaluated primarily on their physical performance characteristics, safety standards, and conformity to established regulations for mechanical and electrical safety. The clearance letter outlines the non-clinical tests performed (safety and performance testing, biocompatibility testing, electrical safety and EMC testing, battery safety testing, and software verification/validation), but these are not the types of studies that involve expert readers, ground truth consensus, or MRMC comparative effectiveness specific to AI diagnostics.
Therefore, I cannot extract the requested information (acceptance criteria in the context of an AI study, sample sizes for test/training sets, data provenance, expert adjudication, MRMC studies, standalone performance, or ground truth establishment relevant to AI/ML) directly from this document, as it pertains to a different type of medical device evaluation.
To directly answer your request based on the provided document, which is for a Portable Oxygen Concentrator (not an AI/ML diagnostic device):
The FDA 510(k) Clearance Letter for the Portable Oxygen Concentrator focuses on demonstrating substantial equivalence to a predicate device through:
- Same Intended Use: Providing supplemental oxygen to adult patients on a prescriptive basis for respiratory therapy.
- Similar Technological Characteristics: Utilizing breath detection, molecular sieve/pressure swing adsorption, and a pulse dose mechanism.
- Performance Data: Presenting specifications like oxygen concentration, pulse volumes, sound levels, and mechanical/electrical safety.
- Compliance with Recognized Standards: Adhering to various international IEC and ISO standards for medical electrical equipment, biocompatibility, and oxygen concentrators.
The "acceptance criteria" for a device of this type are generally meeting the performance specifications and safety standards outlined in the non-clinical testing section, and demonstrating that any differences from the predicate device do not raise new questions of safety or effectiveness.
Here's a breakdown of the closest equivalents to your requested categories, given the nature of the device and the document:
1. A table of acceptance criteria and the reported device performance
For a portable oxygen concentrator, acceptance criteria are generally related to its physical and performance specifications like oxygen purity, flow rates, noise levels, and battery life, rather than diagnostic accuracy metrics.
| Feature | Acceptance Criteria (Subject Device Specification) | Reported Device Performance (from "Specifications" and "Performance" sections) |
|---|---|---|
| Oxygen Concentration | 90% - 3% /+ 5.5% at all settings | 90% - 3% /+ 5.5% at all settings |
| Inspiratory Trigger Sensitivity | <0.12 cmH2O | <0.12 cmH2O |
| Maximum Outlet Pressure | < 28.9 PSI (199 kPa) | < 28.9 PSI (199 kPa) |
| Nominal Sound Level (at setting 2) | Comparable to predicate (39 dBA typical) and within safe limits for patient use. (Subject device: 42.3 dBA) | 42.3 dBA (at setting 2) |
| Maximum Sound Pressure Level (at max flow setting S) | Comparable to predicate (54 dBA) and within safe limits for patient use. (Subject device: 50.5 dBA) | 50.5 dBA (at maximum flow setting S) |
| Battery Duration | Sufficient for portable use (Predicate: unspecified, but implies multiple hours) | 1.5-4.5 hrs |
| Operating Temperature | -5°C to 40°C (23°F to 104°F) | 23 to 104℉ (-5 to 40℃) |
| Operating Humidity | 5% to 90%, non-condensing | 5% to 90%, non-condensing |
| Operating Altitude | 0 to 5000 meters (0 to 16,400 ft) | 0 to 16,400 ft (0 to 5000 meters) |
| Measurement Uncertainties | Pulse volumes: ± 15% of rated volumePressure: ± 0.03 psig (General) / ± 0.05 cm H2O (Inspiratory Trigger Sensitivity)Oxygen concentration: ± 3% (not accounting for temperature, barometric pressure, and time from measurement device calibration) | Stated as listed. |
| Compliance with Standards | Adherence to relevant IEC and ISO standards (e.g., IEC 60601-1, ISO 80601-2-69, ISO 18562 series, IEC 62133-2) | Demonstrated through non-clinical testing. |
Study Proving Acceptance Criteria:
The study proving the device meets its acceptance criteria is primarily through the Non-Clinical Testing Summary described in Section VIII of the 510(k) Summary.
- Safety and Performance Testing: This involved evaluations against ISO 80601-2-69:2020 and ISO 80601-2-67:2020 (standards for oxygen concentrators and oxygen-conserving equipment), and internal bench testing.
- Biocompatibility Testing: Conducted per ISO 18562 series.
- Electrical Safety and EMC Testing: Evaluated per IEC 60601 series standards.
- Battery Safety Testing: Conducted per IEC 62133-2.
- Software Verification and Validation: Conducted per FDA guidance.
These tests collectively demonstrate that the device performs according to its specifications and is safe for its intended use, proving that it meets its "acceptance criteria" for a physical medical device.
2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
- Sample Size for Test Set: Not applicable in the context of an AI/ML test set. For a portable oxygen concentrator, testing involves physical devices. The non-clinical tests would have been performed on a representative sample of manufactured devices (e.g., a certain number of units for durability, environmental, and performance tests). The document does not specify the exact number of physical units tested, as this is standard engineering validation rather than a clinical study with patient data.
- Data Provenance: Not applicable in the context of AI/ML data. This device is tested through engineering bench testing, not clinical data sets. The manufacturer is Nanjing Yinuoji Medical Technology Co., Ltd. in China, so device testing would likely be performed there or at accredited labs globally. The data is prospective in the sense that physical devices were manufactured and then tested, but not in the "retrospective/prospective data collection" sense typically associated with AI/ML studies where patient data is gathered.
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. "Ground truth" in the context of AI/ML is about establishing a definitive diagnosis or label for medical images or patient data. For a portable oxygen concentrator, "ground truth" is established by direct physical measurement (e.g., using calibrated sensors to measure oxygen concentration, flow rates, sound levels) and adherence to engineering and safety standards by qualified engineers and technicians. No clinical "experts" in the sense of radiologists or pathologists establishing ground truth for diagnostic accuracy are involved.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
- Not applicable. This is a concept for reconciling disagreements among human readers or labelers in AI/ML dataset creation. Device performance testing relies on objective measurements against established engineering specifications and international standards, not subjective 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
- Not applicable. MRMC studies are specifically designed to assess the impact of AI algorithms on human diagnostic performance (e.g., how AI assistance affects radiologists' accuracy). This device does not have an AI component that assists human readers in diagnosis.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- While the device has software, "standalone performance" in the AI/ML context refers to the algorithmic performance in diagnostic tasks without human input. Here, the "standalone performance" is the device's ability to mechanically and electronically produce and deliver oxygen according to its specifications, which was tested via Internal Bench Testing and compliance with ISO standards.
7. The type of ground truth used (expert concensus, pathology, outcomes data, etc)
- As explained in #3, "ground truth" for this device comes from objective physical measurements against predefined engineering specifications and international medical device performance and safety standards. For example, oxygen concentration is measured by an oxygen analyzer, flow rates by flow meters, sound by calibrated sound level meters, etc.
8. The sample size for the training set
- Not applicable. This device is not an AI/ML algorithm that requires a "training set" of data. Its functionality is based on established mechatronic and chemical-physical principles (Pressure Swing Adsorption).
9. How the ground truth for the training set was established
- Not applicable, as there is no "training set" for this type of device.

The Jumao JM-P50A Portable Oxygen Concentrator provides a high concentration of supplemental oxygen to adult patients (ages 22 and older) requiring respiratory therapy on a prescriptive basis. It may be used in the home or in professional healthcare facility.
Portable Oxygen Concentrator, model: JM-P50A is a portable oxygen generator that is intended to release oxygen for respiratory therapy by physical means (a molecular sieve). It supplies a pulsed high concentration of oxygen and is used with a nasal cannula (supplied separately) to channel oxygen from the concentrator to the patient. The JM-P50A is small, portable and may be used in the home or in a professional healthcare facility.
Portable Oxygen Concentrator, model: JM-P50A, 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 air tank. 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.
Portable Oxygen Concentrator, model: JM-P50A, can be used in the home or in a professional healthcare facility. Power options include 100 – 240 V (50- 60Hz) AC power supply, rechargeable battery packs.
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. Portable Oxygen Concentrator, model: JM-P50A, senses the beginning of the inhalation cycle 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 portable oxygen concentrator consists of main unit, battery, power adapter and carry case. The main gas pathway of oxygen concentrator is composed of particle filter, particle filters, air compressor, molecular sieve beds, manifold valve, sensors, air tank.
This is a 510(k) clearance letter for a Portable Oxygen Concentrator (JM-P50A). The document primarily focuses on demonstrating substantial equivalence to a predicate device (Inogen Rove 6 Portable Oxygen Concentrator) through bench testing and compliance with recognized consensus standards. It explicitly states that "There was no clinical testing performed."
Therefore, the provided document does not contain information about acceptance criteria and a study proving the device meets those criteria in the context of clinical performance or human-in-the-loop assessment. The information you're asking for, particularly points 1-7 from your prompt, typically applies to studies proving clinical effectiveness or diagnostic accuracy of AI/software as a medical device (SaMD), which is not the case here.
However, I can extract information related to the device's technical specifications and how its performance was evaluated against standards, which serve as a form of acceptance criteria for this type of device.
Here's an interpretation based on the provided document, addressing what can be extracted and noting what cannot be:

The FreeStyle Comfort Oxygen Concentrator can deliver concentrated oxygen with either a fixed-minute pulse delivery or can be set to operate using autoSAT pulse delivery. The FreeStyle Comfort is used on a prescriptive basis by patients requiring supplemental oxygen to increase blood oxygen saturation. FreeStyle Comfort may be used in the home, institution, and transport modes.
The FreeStyle® Comfort® is a reusable, lightweight portable oxygen concentrator weighing 5 lbs. (2.3 kg) with the lithium-ion single battery pack, and 6 lbs. (2.7 kg) with the optional lithium-ion double battery pack. The FreeStyle Comfort's light weight and portability allow the user to receive supplemental oxygen while traveling, shopping or while at home. The FreeStyle® Comfort® complies with FAA guidelines for use onboard commercial aircraft.
The FreeStyle® Comfort® oxygen concentrator has 5 flow settings delivering up to 1050 mL of concentrated oxygen per minute. The subject device has two delivery options, autoSAT® Pulse or Fixed Minute Pulse, providing 90% (+5.5% / -3%) of concentrated oxygen. Like the predicate device, the FreeStyle® Comfort® releases a pulse of oxygen (bolus) at the beginning of inhalation by using oxygen conserving technologies. The oxygen conserving technology detects inhalation and quickly delivers a pulse of oxygen to the user. This method of oxygen delivery increases device portability, ambulation, and battery life for extended use away from the home, as compared with continuous O2 flow oxygen concentrators.
The outer enclosure of the FreeStyle® Comfort® is made of UL/CSA-approved PC/ABS plastic. The innerworkings include two alloy cylinders, each filled with molecular sieve (referred to as sieve beds), an internal piston air compressor, valves, tubing assembly, electrical wiring harness, filters, and control board.
FreeStyle® Comfort® does not require sterilization and is not a single use device.
Operating Principles
The control board uses software to operate the unit. The device operating principle is a process known as Pressure Swing Adsorption, or PSA. Air is drawn into the device through the air intakes to the air compressor. Pressurized air flows from the air compressor to each of the (molecular) sieve beds in cycles. As one sieve bed is filled with pressurized air, the oxygen passes through the sieve bed. As the oxygen travels through the sieve bed, the nitrogen molecules collect on the molecular sieve. At the end of the cycle, the nitrogen is purged using enriched oxygen, then the process begins again with the alternate sieve bed (one sieve bed depressurizes while the other sieve bed is pressurized). This process continuously repeats from one sieve bed to the other, producing highly concentrated oxygen. Concentrated oxygen flows from the sieve beds to the product tank, then through sensors that measures both oxygen concentration and flow, then delivered to the patient.
AutoSAT Feature
Traditional pulse dosing supplies the same amount of oxygen delivered to the patient per minute regardless of the number of breaths taken. If the patient inhales more often, such as during physical activity like walking, the amount of oxygen delivered decreases per breath to maintain the same volume of oxygen per minute. The autoSAT (automatic titration to patient's respiratory rate) function delivers a consistent pulse dose (bolus) volume of oxygen (up to 40 breaths per minute). As breath rate increases during physical activity, the amount of oxygen delivered will stay the same per breath, which increases the volume of oxygen delivered per minute.
The autoSAT function is a default setting in the FreeStyle Comfort. The user can change the setting to traditional dosing by using the membrane touchpad to switch off the autoSAT function. During normal operation, if after more than 15 seconds the device does not detect breath inhalation, the device will automatically begin dosing @ 20 breaths per minute until breath inhalation is detected. Upon detection, the device will resume normal operation in autoSAT mode.
Inhalation Sensitivity
The FreeStyle® Comfort® offers an inhalation sensitivity mode. The user can adjust the sensitivity settings values from 1-5, where 1 is the least sensitive, 5 is the most sensitive. The sensitivity function has a default setting of >-0.1 cm H2O and a maximum adjustable range of -0.3 to -0.40 cm H2O, negative pressure (inhalation) to trigger the flow (bolus) of O2 to the user. In cases where shallow breathing cannot be detected at the device (default) sensitivity setting, the user can adjust the setting with the membrane keypad to increase inhalation sensitivity to trigger oxygen delivery at the desired flow setting.
Power Options
FreeStyle Comfort is powered with either a single or double lithium-Ion battery pack or with an external AC/DC power source (A/C wall outlet or DC vehicle). FreeStyle® Comfort® includes a built-in battery charger that will automatically recharge the battery pack when the unit is plugged into an external power source, except during use on a commercial aircraft. When an AC/DC power source is not readily available for battery recharge, the battery pack can easily be removed for quick replacement by pressing the battery release button and sliding the battery pack out from the device.
Device battery is capable of up to 8 hours of operation using the 8-cell battery, and 16 hours with the 16-cell battery, depending on the selected flow setting and user's breathing rate. The battery charge status is displayed on the keypad LCD during normal operation.
User Interface
The touch membrane keypad display allows the user to operate the device. The user can select the desired pulse dose volume and view the operating status. Once the user completes the selection process, the display screen will enter "standby" mode and then dims after 20 seconds. Pressing any button on the keypad will wake the display screen from standby mode. Oxygen delivery from the device to the user is channelled via a nasal cannula/tubing assembly, manufacturer Salter Labs (SunMed, LLC.), P/N 1600 (K911740). The end user is required to follow the cannula manufacturer's instructions for length of use, maintenance, and replacement requirements.
Keypad/Alarms
Operating information, battery, and operating status is displayed on the keypad LCD window. The subject device comes equipped with both visual and audible alarms.
The FreeStyle Comfort features the following visual and audio safety alarms:
- Low oxygen concentration
- System malfunction due to high temperature, high system pressure or compressor fault
- System malfunction due to low temperature, low pressure or fan failure
- Flow Rate failure due to obstruction of gas pathway (cannula blockage)
- Low battery (activates at 20% battery power and intensifies alarm at 5% battery power)
- Auto-dosing until warm up is complete and breath detection is activated
- After 15 seconds of no breath detected the unit shifts from autoSAT to auto-dose.
Wireless Connectivity
The FreeStyle Oxygen Concentrator utilizes Bluetooth technology that pairs the portable oxygen concentrator to a mobile device or tablet using the myCAIRE App.
The myCAIRE™ app connects patients with home care providers (DME), allowing DMEs to view usage hours and flow settings of a connected CAIRE oxygen concentrator. The system uses wireless technology (BLE) to transmit information from the concentrator to a smart device, which then sends it to the home care provider. Home care providers can assist patients by addressing device notifications and supplying recommendations for troubleshooting remotely.
myCAIRE™ shares data from CAIRE oxygen concentrators without altering settings, performance, or therapy. It is not intended for monitoring, diagnosis, or treatment. The connection only sends data to the app in raw format, decodable solely by Caire, with no Protected Health Information or Personally Identifiable Information transmitted.
Associated Accessories
The device comes equipped with a rechargeable 8-cell lithium-Ion battery pack, A/C power supply/cord, DC power supply. Optional equipment consists of a 16-cell lithium-Ion battery pack for extended use and the desktop battery charger.

The provided FDA 510(k) clearance letter and summary for the FreeStyle Comfort Oxygen Concentrator do not contain information about studies involving acceptance criteria related to a device's performance with human readers or AI assistance.
This document focuses on establishing substantial equivalence for a medical device (an oxygen concentrator) based on its technological characteristics, intended use, and adherence to performance standards, rather than evaluating an AI algorithm's diagnostic performance in a clinical setting. Therefore, the requested information categories are not applicable to the provided text.
Specifically, the document does not mention:
- A table of acceptance criteria and reported device performance in relation to AI performance or human reader analysis. It provides specifications for the oxygen concentrator itself, such as oxygen concentration, flow settings, and physical dimensions.
- Sample size, data provenance, number of experts, qualifications of experts, or adjudication methods for a test set to establish ground truth for an AI system.
- Multi-Reader Multi-Case (MRMC) comparative effectiveness study or effect size of human readers with/without AI assistance.
- Standalone (algorithm only) performance.
- Training set sample size or ground truth establishment for a training set. The training set concept is relevant to AI/machine learning models, which are not described in this submission.
The "studies" mentioned in the document are primarily non-clinical engineering and safety tests to ensure the device meets recognized international standards for medical electrical equipment and oxygen concentrators. These include:
- Non-clinical Testing:
ISO 80601-2-69(Particular Requirements for Basic Safety and Essential Performance of Oxygen Concentrator Equipment)ISO 80601-2-67(Particular Requirements for Basic Safety and Essential Performance of Oxygen-Conserving Equipment)- Tests for Pulse, volume; Pulse Time; Trigger Sensitivity; Oxygen Concentration Performance; Oxygen Sensor Accuracy; Visible/Audible Alarms
- Software verification and validation
- Electrical Safety / Electro-Magnetic Compatibility (EMC) / RFID
- Biocompatibility (
ISO 18562-2:2017- Particulate matter,ISO 18562-3:2017- Volatile organic compounds) - Sound testing.
The acceptance criteria for the FreeStyle Comfort Oxygen Concentrator are implicit in its performance specifications (e.g., Oxygen Concentration of 90% +5.5% / -3%) and its successful demonstration of compliance with the listed ISO/IEC standards. The "study" proving it meets these criteria is the suite of non-clinical tests described.
In summary, the provided text describes a medical device (oxygen concentrator) and its regulatory clearance process, which differs significantly from the evaluation pathway for AI-powered diagnostic devices. Therefore, the questions related to AI algorithm performance are not answerable from this document.
