The OxyMinder is intended for continuous monitoring of the concentration of oxygen being delivered to patients ranging from newborns to adults. This device can be used in the hospital and subacute settings. The monitor is not intended as a life supporting device or for diagnostics.
The OxyMinder is an air / oxygen blender mounted oxygen monitor capable of measuring the oxygen concentration from 18 to 100%. A Bio-Med specified oxygen sensor mounted to the blender outputs a voltage which is used by the OxyMinder to determine the concentration of oxygen. The OxyMinder calibrates at ambient air (21%) and 100% oxygen. The OxyMinder is software controlled. To measure the gas mixture of the blender the OxyMinder takes a sample of the gases to the sensor through a separate port and manifold which is separate from the gas pathway to the patient. This sample is then exhausted to the room. The OxyMinder sampling stream is not part of the gas pathway to the patient.
The OxyMinder is used for continuous monitoring of the concentration of oxygen delivered to patients via air oxygen blenders. The monitor provides the following features:
- Continuously displays the concentrated Oxygen level delivered to a patient.
- Accepts user inputs via touch screen or button (power button).
- Provides visual alarm messages, and audible alarms.
- Displays the current alarm setting levels (High and Low O2 alarms).
- Provides on-screen configuration tools such as O2 sensor calibration, touchscreen calibration, audio test, etc.
- Monitors and displays the battery level and power source.
- Ensures clean hospital airlines by automatically purging system periodically.
The OxyMinder is designed to be mounted to a Bio-Med Devices air / oxygen blender via a manifold that houses the oxygen sensor and a solenoid.
In addition to the primary function of monitoring oxygen concentration, the OxyMinder provides an automatic gas supply line purge function.
The provided text is related to a 510(k) premarket notification for the "OxyMinder" device, an oxygen gas analyzer. It describes the device, its intended use, and compares it to a predicate device (Maxtec MaxO2ME). The document states that "A series of non-clinical performance / bench testing was performed" and lists the types of tests, concluding that "The test results met the applicable standards and are similar to the reported performance of the predicate device." However, the document does not provide detailed acceptance criteria or the specific results of these tests. It only broadly states that the performance was similar to the predicate and met applicable standards.
Therefore, many of the requested details about the study cannot be extracted from this document.
Here's a summary of what can be inferred or explicitly stated:

Study Details:
-
Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective):
- The document mentions "a series of non-clinical performance / bench testing" but does not specify the sample size for any of these tests nor the data provenance. It implies laboratory testing rather than patient data.
-
Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- Not applicable/Not provided. The testing appears to be bench/performance testing against specifications and standards, not expert-adjudicated clinical data.
-
Adjudication method (e.g. 2+1, 3+1, none) for the test set:
- Not applicable/Not provided.
-
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:
- No MRMC or human-in-the-loop study was done or mentioned. This is a standalone oxygen analyzer, not an AI-assisted diagnostic tool.
-
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- Yes, performance testing was done on the device (OxyMinder) as a standalone unit. The "Oxygen Accuracy with Blender" test refers to its performance when integrated with a Bio-Med Devices air/oxygen blender, but it's still about the device's accuracy rather than human interpretation.
-
The type of ground truth used (expert consensus, pathology, outcomes data, etc):
- For the bench testing, the "ground truth" would be the known and controlled oxygen concentrations and environmental conditions used during calibration and testing against established performance standards and specifications.
-
The sample size for the training set:
- Not applicable. This device is not described as using machine learning or AI that would require a 'training set' in the traditional sense. It's an oxygen gas analyzer, likely with embedded software and algorithms based on known physics and engineering principles for sensor readings.
-
How the ground truth for the training set was established:
- Not applicable, as there's no mention of a training set for machine learning.

Substantial Equivalence Discussion and Rationale
The table above compares the key features of the proposed device with the identified predicate -Maxtec MaxO2ME (K153659). The comparison demonstrates that the proposed devices can be found to be substantially equivalent.
Indications for Use -
The indications for use are similar for the proposed device when compared to the predicate device.
Discussion - Both devices are indicated for use for monitoring oxygen levels. Both devices have equivalent range and accuracy specification. Both devices have similar alarm functionality. Minor difference does not raise different concerns of risk than the predicate.
Technology and construction -
The technology is identical to the predicate device using a galvanic fuel cell for measurement technology.
Discussion - The differences in how the gas is measured and additional features do not raise different concerns of safety or effectiveness compared to the predicate.
Environment of Use -
The environments of use are similar to predicate which are clinical settings. Discussion - The subject device does not include pre-hospital which is in keeping with its use with the compatible Bio-Med Devices air / oxygen blender.
Patient Population -
The patient population of the predicate device is newborns to adults as is the subject device. Discussion - The subject and predicate have identical patient populations
Non-Clinical Testing Summary -
A series of non-clinical performance / bench testing was performed that includes:
- Shelf-life / Aging ●
- Software Verification and Validation ●
- IEC 60601-1 ●
- IEC 60601-1-2
- IEC 60601-1-8 ●
- IEC 80601-2-55
- Auto-purge functionality ●
- Oxygen Accuracy with Blender ●
- Battery Performance Testing ●
Discussion - The test results met the applicable standards and are similar to the reported performance of the predicate device.
Biocompatibility -
The predicate device has materials in the gas pathway, the subject device does not. Discussion - As the subject device has not patient contacting materials (indirect or gas pathway) biocompatibility testing is not applicable
{9}------------------------------------------------
Discussion of Differences –
There are no significant differences in critical function between the proposed device and the predicate device. The subject device is intended to specifically be used with only a Bio-Med Devices cleared air / oxygen blender. A secondary feature of the OxyMinder is the auto-purge feature, which mitigates gas line contamination in the hospital medical gas pipelines due to minimal backflow when air/oxygen blender is left connected and unused for extended periods of time. The predicate device is not limited to use with only an air / oxygen blender, has a manual purge feature when it is in use, and can be used in the pre-hospital environment.
The performance testing has demonstrated that the subject device met the applicable standard performance requirements. The above table plus the risk analysis do not identify any new or different risks compared to the predicate.
Substantial Equivalence Conclusion
The sponsor has demonstrated through performance testing, design and features, and non-clinical testing that the proposed device and predicate have been found to be substantially equivalent.
