Intended Use

The Tenacore Oxygen Blender, is intended for non-invasive mixing and delivery of a ratio of therapeutic oxygen and medical grade air as a stand-alone unit or as a component of a respiratory support apparatus.

Device Description

The Tenacore Oxygen Blender is typically a wall-mounted unit that provides inlets for medical grade air and therapeutic oxygen. The percentage of oxygen to air can be adjusted from 21-100%.

AI/ML Overview

The Tenacore Oxygen Blender is intended for non-invasive mixing and delivery of a ratio of therapeutic oxygen and medical grade air as a stand-alone unit or as a component of a respiratory support apparatus.

Here's an analysis of the provided information regarding acceptance criteria and the study:

1. Table of Acceptance Criteria and Reported Device Performance

Acceptance CriteriaReported Device Performance
Accuracy: +/- 3%Accuracy: +/- 3%

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

The document does not specify the sample size used for the test set or the data provenance (e.g., country of origin, retrospective or prospective).

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

This information is not applicable as the study described is a performance test for a medical device's physical specifications (accuracy) and not an evaluation based on expert interpretation of data like medical images.

4. Adjudication Method for the Test Set

This information is not applicable for the type of performance testing described. Adjudication typically refers to resolving discrepancies between multiple expert interpretations.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

No MRMC comparative effectiveness study was mentioned. The study focuses on the device's technical performance, not on human-in-the-loop improvements with AI.

6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study

Yes, a standalone study was performed. The "Performance Data & Conclusions" section indicates that "Performance testing was conducted as required by standards," which refers to the device itself meeting specified technical standards like accuracy.

7. Type of Ground Truth Used

The ground truth used was based on established engineering and medical device standards for oxygen blenders. Specifically, the device was tested against standards such as EN ISO 15001:2004, 60601-1, 9703-3:1998, 601-1:1988, and IEC 79-4:1975 to verify its accuracy and other performance parameters.

8. Sample Size for the Training Set

This information is not applicable. The device is a mechanical oxygen blender, not an AI/machine learning model that requires a training set.

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

This information is not applicable as there is no training set for this type of device.

Dear Mr. Caso:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting vour device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition. FDA may publish further announcements concerning your device in the Federal Register.
