No
The document describes a heated humidifier system and its components, focusing on the physical delivery and warming of breathing gases. There is no mention of AI or ML in the intended use, device description, or performance studies.

Yes
The device is intended to add moisture to and warm breathing gases administered to patients, which helps prevent damage or irritation to the respiratory tract and desiccation of secretions, addressing a medical condition.

No

The device is intended to add moisture and warmth to breathing gases for administration to a patient, and to deliver or humidify these gases. Its purpose is therapeutic, not diagnostic.

No

The device description explicitly lists hardware components such as a heated humidifier, humidification chamber, heated wire circuits, temperature probes, heated wire adapters, and a power cord.

Based on the provided text, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • Device Function: The AirLife DuoTherm™ Humidification System is designed to add moisture and warmth to breathing gases that are delivered to a patient's airway. It is a respiratory support device, not a diagnostic test.
  • Intended Use: The intended use clearly states that the device is for administering breathing gases to a patient, not for analyzing biological samples.

The device's function and intended use fall under the category of respiratory therapy devices, not in vitro diagnostics.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Non-clinical performance testing was conducted according to various ISO and IEC standards related to medical electrical equipment, respiratory humidifying equipment, electromagnetic compatibility, usability, alarm systems, software life cycle processes, and conical connectors for anaesthetic and respiratory equipment. Biocompatibility testing was also performed according to ISO 18562 and ISO 10993 series for breathing gas pathways and biological evaluation of medical devices.
There was no clinical testing required to support the AirLife DuoTherm™ Humidification System, as the intended use and indications for use are equivalent to the primary predicate and reference devices.

Dear Megan Walsh:

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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).

  • Clinical Performance Data (21 CFR §807.92(b)(2)): There was no clinical testing required to . support the AirLife DuoTherm™ Humidification System, as the intended use and indications for use are equivalent to the primary predicate and reference devices. These types of devices, including the primary predicate device, have been on the market with a proven safety and efficacy record for the use of the device. The non-clinical testing detailed in this submission supports the substantial equivalence of the AirLife DuoTherm™ Humidification System, and its safety and effectiveness.

VIII. Substantial Equivalence Conclusion (21 CFR §807.92(b)(2))

The AirLife DuoTherm™ Humidification System is substantially equivalent in intended use and fundamental scientific technology to the following legally marketed device in commercial distribution: MR850 Heated Humidifier (K033710). The AirLife DuoTherm™ Humidification System met all specified criteria and did not raise new safety and/or effectiveness questions. The substantial equivalence of the subject device is based on similar indications for use, fundamental technology, including design, and operational principles. Based on the similarities to the primary predicate device, reference devices, and performance data, the AirLife DuoTherm™ Humidification System is substantially equivalent to its primary predicate device (K033710) and reference devices.
