The provided text describes the acceptance criteria and the studies performed for the Bluepoint Medical Airway Gas Sampling Products, but it does not contain information typically associated with AI/ML device studies, such as training sets, test sets, expert adjudication, or MRMC studies. This is a medical device clearance, not an AI/ML software clearance.

Based on the document, here's the information regarding the acceptance criteria and a detailed description of the studies:

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

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

The document does not specify exact sample sizes for each test mentioned (e.g., how many units were tested for biocompatibility or performance). It generally states that "Performance testing was executed on new device samples and on samples that have undergone accelerated aging to the duration of the proposed shelf life of three years." Data provenance is not mentioned beyond the fact that the tests were performed by Bluepoint Medical GmbH & Co. KG.

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

This information is not applicable and is not provided in the document. The studies performed are engineering and laboratory tests based on established medical device standards, not human expert evaluations of medical images or data.

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

This information is not applicable and is not provided in the document. The studies performed are objective laboratory and engineering tests, not subjective evaluations requiring 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

No such study was done. This device is a passive medical accessory (airway gas sampling product), not an AI/ML diagnostic or assistive device that would involve human readers or AI assistance.

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

This information is not applicable as the device is a physical medical accessory, not an algorithm or software. It does not have a "standalone" algorithmic performance.

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

The "ground truth" for the device's performance is established by recognized international standards and specifications for medical devices. For example:

• Biocompatibility: Determined by adherence to ISO 10993 series and ISO 18562 series, along with chemical characterization and inhalation risk assessment.
• Performance (Accuracy, Response Time): Determined by meeting specific thresholds set by ISO 80601-2-55 for respiratory gas monitors.
• Physical Compatibility: Determined by adherence to ISO 5356-1, ISO 594-1, and ISO 594-2 for various connectors.
• Risk Management: Determined by compliance with ISO 14971.

8. The sample size for the training set

This information is not applicable and is not provided. The development and testing of this type of medical device do not typically involve "training sets" in the context of AI/ML. The device is designed and validated through engineering principles and compliance with standards.

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

This information is not applicable. There is no concept of a "training set" or "ground truth" for a training set in the context of this device's development as described in the document.

In summary: The provided document describes the clearance of a non-AI/ML medical device. The acceptance criteria and testing are focused on demonstrating compliance with established physical, mechanical, and biological safety standards for medical accessories. Therefore, many of the questions related to AI/ML device studies (training sets, expert adjudication, MRMC studies) are not applicable to this submission.

The Nellcor Flexible SpO2 Sensors, models FLEXMAX and FLEXMAX-P, are indicated for use with monitoring systems that use Nellcor OxiMax and Nellcor compatible pulse oximeters.

The Nellcor Flexible SpO2 Sensors are intended for use in non-invasive continuous or spot-check monitoring of functional oxygen saturation of arterial hemoglobin (SpO2) and pulse rate. The sensor size range includes a large and small sensor. The sensors are intended for use on adult and pediatric (excluding infant and neonatal) patients weighing greater than 20kg.

The use environment may include: hospital-type facilities, intra-hospital transport, mobile emergency medical applications including both ground and air transport, and home use. Transport environments may include intra-hospital transport and both ground and air emergency transport: road ambulances and fixed-wing aircraft and helicopters. The use is dependent upon the use environments specified for the monitoring system utilized in conjunction with the sensor.

The Nellcor Flexible SpO2 Sensors are for prescription use only.

Bluepoint Medical's Nellcor-branded reusable Flexible SpO2 Sensors models FLEXMAX and FLEXMAX-P are pulse oximeter sensors designed and validated for compatibility with Nellcor pulse oximetry and monitoring systems.

Bluepoint Medical reusable Nellcor Flexible SpO2 Sensors models FLEXMAX and FLEXMAX-P are designed for the same functionality as the predicate device sensors, measuring functional oxygen saturation using the patient's finger as the measurement site. They are constructed with the following features:

• Unitary flexible silicone rubber housing containing the optical transmitter l and detector

The document provided describes the Nellcor Flexible SpO2 Sensors models FLEXMAX and FLEXMAX-P. Here is an analysis of its acceptance criteria and the study details:

1. Table of Acceptance Criteria and Reported Device Performance

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

• Sample Size for Test Set: The document mentions "healthy adult subjects" for the clinical study but does not specify the exact number of subjects.
• Data Provenance: The clinical study was a "controlled hypoxia study" conducted under an "institutionally approved protocol." The document does not explicitly state the country of origin, but the submission is to the US FDA, implying the study was conducted to meet US regulatory requirements. It is a prospective study given the nature of a controlled hypoxia experiment.

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

• The ground truth for SpO2 accuracy was determined by "arterial oxygen saturation determined by co-oximetry." Co-oximetry is a laboratory measurement, not typically established by human experts. The document does not refer to experts for ground truth establishment.

4. Adjudication Method for the Test Set

• Not applicable, as ground truth was established by co-oximetry, not expert consensus requiring adjudication.

5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study Was Done, and the Effect Size of How Much Human Readers Improve with AI vs without AI Assistance

• No, an MRMC comparative effectiveness study was not done. This device is a pulse oximeter sensor, not an AI-assisted diagnostic tool that would typically involve human reader performance evaluation.

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

• Yes, the clinical accuracy study was a standalone performance evaluation of the device. The sensor's output was compared directly against co-oximetry measurements during controlled hypoxia, independent of human interpretation or intervention beyond standard monitoring procedures.

7. The Type of Ground Truth Used

• The ground truth for SpO2 accuracy in the clinical study was co-oximetry performed on arterial blood samples.

8. The Sample Size for the Training Set

• The document does not mention a training set sample size. This is expected as the device is a medical sensor, not a machine learning or AI algorithm that typically requires a separate training set.

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

• Not applicable, as there is no mention of a training set for this device.
