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.

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.

Regarding the points specific to AI/ML devices, I must state that the document does not provide the requested information for the following reasons:
2. Sample size used for the test set and the data provenance: Not applicable. This document describes testing for a physical device's compliance with engineering standards, not an AI model trained on data. There is no concept of a "test set" from a data perspective. The "testing" refers to bench testing of the physical hardware and embedded software. Data provenance would not be a relevant concept as it pertains to clinical data for AI model training/testing.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. No clinical test set or ground truth established by experts is mentioned. The ground truth for device performance is based on physical measurements against established engineering and medical device standards.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not applicable. No clinical test set requiring expert 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. This is a physical oxygen concentrator, not an AI-assisted diagnostic or therapeutic device that would involve human readers.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done: Not applicable. This refers to a physical device, not a standalone AI algorithm. While it has embedded software, its "performance" is measured by its physical output (oxygen concentration, flow rate) and adherence to safety standards, not by an algorithm's classification or detection accuracy.
7. The type of ground truth used (expert concensus, pathology, outcomes data, etc): Not applicable. The "ground truth" for this device's performance is determined by direct measurement of physical parameters (e.g., oxygen purity, flow volume, noise levels) and compliance with specified engineering and safety standards, as detailed in the "Non-Clinical Tests Performed" section.
8. The sample size for the training set: Not applicable. This is for an AI/ML model, not a physical medical device. The device itself is manufactured; it doesn't "learn" from a training set in the AI sense.
9. How the ground truth for the training set was established: Not applicable. See point 8.
In summary, the provided document is a regulatory submission for a physical Portable Oxygen Concentrator, and therefore, the information requested, which pertains to AI/ML device performance and validation studies, is not present. The "acceptance criteria" and "study that proves the device meets the acceptance criteria" for this device are based on demonstrating compliance with a comprehensive set of recognized consensus engineering and safety standards through non-clinical bench testing.

The Oxygen Concentrator provide supplemental oxygen to patients who require supplemental O2, by separating nitrogen from room air, by way of a molecular sieve, it can be used in the home or health care facility. It is not intended to sustain or support life.
The Oxygen Concentrator is a portable concentrator which could utilize a molecular sieve and pressure swing adsorption to produce the oxygen. The device could separate nitrogen by absorbing through the molecular sieve when the room air enters the device, and allows the enriched oxygen to be collected. The device could provide approximately 90~96% of oxygen to patients on a continuous flow basis at a rate of 1L/min to 10L/min. The nasal cannula are not sold with the device, users need to purchase the accessories by themselves that are legally marketed. The products have not undergone biocompatibility assessment of condensate precipitates according to ISO18562-4, and it is not recommended to use humidification bottles. The maximum altitude the subject device can operate without degradation of concentration is 2000m.
I am sorry, but based on the provided text, I cannot extract the specific acceptance criteria and study details as requested. The document is a 510(k) summary for an Oxygen Concentrator, which primarily compares the subject device to a predicate device and outlines non-clinical tests performed. It does not contain sections detailing acceptance criteria for specific performance metrics with reported results, sample sizes for test sets, expert qualifications for ground truth establishment, adjudication methods, MRMC studies, standalone performance studies, types of ground truth used, or details about the training set.
The document states:
- "Clinical testing was not needed for this 510(k). The non-clinical performance testing described above is sufficient to support that the device can be used safely and effectively."
Therefore, there is no information about a study that would include elements like test set sample sizes, ground truth establishment, expert adjudication, or MRMC studies for this oxygen concentrator.
The "Performance Comparison" table in the document provides technical specifications and comparisons to the predicate device, but these are not presented as "acceptance criteria" with "reported device performance" in the format typically used for studies validating diagnostic or AI-based devices. The reported values are descriptive technical specifications rather than outcomes from a performance study against predefined acceptance criteria.
Therefore, I cannot provide the requested table and details because the provided text does not contain a study demonstrating device performance against explicitly defined acceptance criteria in the manner you described.

The JUMAO Oxygen Concentrator is intended to provide supplemental oxygen to patients with respiratory disorders, by separating nitrogen from room air, by way of a molecular sieve. It is not intended to sustain or support life.
JMC5A Ni oxygen concentrator is made up of mainframe and flowmeter. It is an electronically operated device that separates oxygen from ambient air. It provides high concentration of oxygen directly to patient/user through a nasal cannula or other methods.
The Jumao Oxygen Concentrator is a Pressure Swing Adsorption (PSA) type oxygen concentrator which takes 120V ~ power source as power source. The output of oxygen is 0.5 to 5 liter per minute. Room air enters the piston type compressor via a series of filters for removing dust particles. The output compressed air is directed by a pneumatic valve into one of the two sieve beds which is full of adsorption material - molecular sieve. Nitrogen is adsorbed by the molecular sieve as the pressure increases; oxygen flows through the molecular sieve and concentrates at the sieve bed bottom. The enriched oxygen is divided into two streams; one stream enters a storage tank. The pressurized oxygen is regulated down to the suitable pressure, an adjustable flow meter and out to the patient. At the same time the second bed is in exhausted status, the molecular sieve desorbs nitrogen as the pressure decreases; another oxygen stream from first bed enters the bottom of the second bed, promotes purging the nitrogen and is exhausted into the atmosphere. Two sieve beds exchange the role of oxygen concentration and continue to produce 93% oxygen to the patient.
This document is a 510(k) premarket notification for an Oxygen Concentrator (Model: JMC5A Ni) and primarily focuses on demonstrating substantial equivalence to a predicate device. It is not a study report designed to prove a device meets specific acceptance criteria through clinical or large-scale non-clinical performance studies with detailed statistical analysis.
Therefore, many of the requested details about acceptance criteria, study methodologies, sample sizes for test/training sets, expert involvement, and ground truth establishment are not present in this regulatory submission document as they would be in a dedicated performance study report.
The document states, "No clinical testing has been performed." and primarily relies on non-clinical (bench) testing and a usability study to support substantial equivalence. The "acceptance criteria" discussed are more akin to meeting specific established standards and performance specifications for an oxygen concentrator rather than criteria for an AI/algorithm-driven device's performance metrics (like sensitivity, specificity).
Below, I will extract the available information, noting where the requested details are not provided due to the nature of the document.
