Intended Use
The AirLife DuoTherm™ Humidification System is intended to add moisture and warmth to breathing gases administered to patients that require assistance breathing or mucosal humidification. Gases that are available for medical use do not contain sufficient moisture and may damage or irritate the respiratory tract.
Device Story
AirLife DuoTherm™ Humidification System delivers heated, humidified breathing gases to patients undergoing mechanical ventilation, NIV, or high-flow oxygen therapy. System comprises a heated humidifier unit, humidification chamber, and heated-wire breathing circuits (neonate, pediatric, adult, and adult NIV). Humidifier heats and humidifies gas; chamber holds water; resistance wires in tubing maintain temperature and humidity to prevent condensation and heat loss. Used in professional healthcare environments (hospitals, subacute care) by trained personnel. Output is conditioned gas delivered to patient airway; helps prevent respiratory tract damage/irritation and secretion desiccation. Device is non-sterile and reusable (humidifier) or single-use (chamber/circuits).
Clinical Evidence
No clinical data provided. Substantial equivalence is supported by non-clinical performance testing, including electrical safety (IEC 60601-1), electromagnetic compatibility (IEC 60601-1-2), usability (IEC 60601-1-6, IEC 62366-1), and extensive biocompatibility testing (ISO 10993 series and ISO 18562 series) for breathing gas pathways.
Technological Characteristics
Heated humidifier with reusable temperature probes, heated wire adapters, and power cord. Includes humidification chamber and heated-wire circuits (neonate, pediatric, adult). Operates via resistance wires in tubing to maintain temperature/humidity. Complies with ISO 80601-2-74, IEC 60601-1, IEC 60601-1-2, IEC 60601-1-8, ISO 5356-1, and ISO 5367. Biocompatibility per ISO 10993 and ISO 18562. Software life cycle per IEC 62304.
Indications for Use
Indicated for neonates, infants, children, and adults (0.5kg to >30kg) requiring mechanical ventilation, positive pressure breathing, or general medical gases. Used for flow rates >1 LPM (neonate), >2 LPM (pediatric), >3 LPM (adult), and >5 LPM (adult NIV).

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.
{1}------------------------------------------------
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.

- 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.
