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

The document does not detail specific sample sizes for particular performance tests. The studies conducted are described as "Device design was qualified through the following tests and assessments" which implies these were bench and lab-based tests, not human studies. Therefore, typical "sample sizes" (as in patient data) and "data provenance" (e.g., country of origin, retrospective/prospective) are not applicable in the context of this device's premarket submission, which focuses on engineering, safety, and performance characteristics rather than clinical diagnostic accuracy. The studies performed are:

  • Electrical Safety
  • Electromagnetic Compatibility
  • Biocompatibility Assessment
  • Cleaning Validation
  • Software Validation
  • Packaging and Shipping
  • Performance: physical (cycling), resistance to flow, spillage, flow sensing, sound power level, humidification output, out of water shutdown, temperature, runtime, warm-up duration, and reservoir gas leak

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

This section is not applicable. The device relies on physical and electrical performance data, and compliance with engineering standards (e.g., ISO 8185, IEC 60601-1). Ground truth is established by the specifications defined in these standards and by direct laboratory measurements, not by expert interpretation of patient data.

4. Adjudication Method for the Test Set

This section is not applicable. Adjudication methods (e.g., 2+1, 3+1) are typically used in clinical studies where multiple experts evaluate ambiguous cases to reach a consensus for ground truth. This submission focuses on engineering and performance testing, where outcomes are determined by objective measurements against predefined criteria.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done

No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not done. This type of study is typically performed for diagnostic devices where human readers (e.g., radiologists) interpret images or data, and their performance with and without AI assistance is compared. The Transcend Heated Humidifier is a therapeutic accessory, not a diagnostic device involving human interpretation of complex data.

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

This section is not applicable in the typical sense of AI algorithms. The "device" itself operates "standalone" in its function as a humidifier, based on its internal programming and hardware. However, it's not an AI algorithm in the context of data analysis or diagnostic support where a "human-in-the-loop" would be relevant. The software validation mentioned ensures the device's internal algorithms and controls function correctly, which is a standalone performance test.

7. The Type of Ground Truth Used

The ground truth for the device's performance is based on:

  • Engineering Standards and Specifications: Metrics defined by standards such as ISO 8185 (e.g., maximum output humidity, pressure drop, gas leak, sound power level, temperatures).
  • Predicate Device Characteristics: Direct comparison of physical, functional, and safety attributes against a legally marketed predicate device.
  • Laboratory Measurements: Objective measurements of the device's performance against the specified criteria (e.g., humidification output, temperature, water capacity).

8. The Sample Size for the Training Set

This section is not applicable. This device is not an AI/machine learning model where a "training set" of data would be used to develop an algorithm. Its design and validation are based on traditional engineering principles and testing.

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

This section is not applicable as there is no "training set" in the context of this device.

Dear Ms. Swanson:

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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your 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.
