Intended Use

O2 Nasal Cannula with CO2 monitoring is intended for use in Adult patients who require supplemental oxygen delivery and CO2 monitoring

Device Description

O2 Nasal cannula with CO2 monitoring that is intended to situate under the patients nose with the prongs of the cannula inserted into patients nostrils where oxygen is administered and CO2 monitored. The O2 Nasal cannula with CO2 monitoring has two co-extruded tubes

AI/ML Overview

This document is a 510(k) Summary for the Flexicare O2 Nasal cannula with CO2 monitoring. It details the device's characteristics and its substantial equivalence to a predicate device, but it does not describe acceptance criteria for an AI/ML powered device nor a study proving performance against such criteria.

The document addresses a medical device that does not incorporate AI/ML. Therefore, much of the requested information regarding AI/ML-specific testing (e.g., sample size for test/training sets, expert ground truth, adjudication methods, MRMC studies, standalone performance) is not applicable and is not present in the provided text.

Here's an analysis based on the information provided, highlighting the absence of AI/ML-specific details:

1. Table of Acceptance Criteria and Reported Device Performance

The document sets out various physical and functional tests, comparing the Flexicare O2 Nasal cannula with CO2 monitoring to established standards and the predicate device. The "acceptance criteria" here are generally compliance with physical dimensions, material properties, and functional performance as outlined by relevant EN and ISO standards, or as performing "at least as well as" the predicate device.

Acceptance Criteria CategorySpecific Criteria / StandardReported Device PerformanceComments

The study proving the device meets these criteria is described as "Tests Performed" on page 3 and summarized on page 4. It states: "All Samples passed the performance testing when tested against methods House test methods and relevant BS EN standards. The results of this testing show that the O2 Nasal cannula with CO2 monitor...performs at least as well as marketed predicate dev Unomedical."

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

  • Sample Size: The document does not specify a numerical sample size for the "test set" (i.e., the number of cannulas tested). It generically refers to "All Samples."
  • Data Provenance: Not applicable in the context of device performance testing. The tests are physical and functional evaluations of manufactured units, not data-driven intelligence.

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

This is not applicable as the device is a physical medical device, not an AI/ML system requiring expert ground truth for classification or diagnosis. The "ground truth" for this device's performance is objective measurement against engineering specifications and industry standards.

4. Adjudication Method for the Test Set

This is not applicable as there is no human interpretation or classification involved that would require adjudication. Performance is measured objectively.

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, an MRMC study was not done, and this question is not applicable because the device is a physical nasal cannula, not an AI-assisted diagnostic or clinical decision support system.

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

This is not applicable as the device is a physical medical device, not an algorithm.

7. The Type of Ground Truth Used

The "ground truth" for this device's performance is based on engineering specifications, dimensional tolerances, and compliance with recognized industry standards (e.g., BS EN 13544-2, ISO 594-1, ISO 594-2). In-house test methods are also used for aspects not covered by specific standards. The implicit ground truth for "at least as well as" is the performance of the predicate device.

8. The Sample Size for the Training Set

This information is not applicable as the device is not an AI/ML system and does not have a "training set."

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

This information is not applicable as the device is not an AI/ML system and does not have a "training set."
