Intended Use
Fenom Pro is a portable, non-invasive device to measure fractional exhaled nitric oxide (FENO) in human breath. FENO is increased in some airway inflammatory processes, such as asthma, and decreases in response to anti-inflammatory treatment. Fenom Pro measures fractional exhaled nitric oxide according to guidelines established by the American Thoracic Society. Measurement of FENO by Fenom Pro is a non-invasive quantitative method to measure the decrease in FENO concentration in asthma patients that often occurs after treatment with anti-inflammatory pharmacological therapy as an indication of therapeutic effect in patients with elevated FENO measurements are to be used as an adjunct to established clinical assessments. Fenom Pro is suitable for adults and children 6 years and older. Fenom Pro should be used in a point-of-care healthcare setting under professional supervision. Fenom Pro should not be used in critical care, emergency care or in anesthesiology.
Device Description
Fenom Pro is a non-invasive point-of-care breath analyzer for the quantitative measurement of fractional exhaled nitric oxide (FENO) in expired human breath. Fenom Pro is comprised of four major components. The main unit contains a touch screen interface for the user and houses the nitric oxide sensor and pneumatics needed to sample the patient's breath. The patient exhales into the Fenom Pro though a single use disposable mouthpiece which is attached to the handpiece. The handpiece is connected to the main unit via a breath tube. For testing, the patient inhales to total lung capacity and then slowly exhales into the mouthpiece for 6 or 10 seconds, depending on the mode of operation. Approximately 28 seconds after a successful breath maneuver, the FENO concentration is displayed in parts per billion (ppb) on the device touch screen. The device has a daily quality control procedure to ensure consistent device performance.
More Information

No
The summary describes a device that measures FENO using a nitric oxide sensor and pneumatics. There is no mention of AI, ML, or any algorithms that would suggest the use of such technologies for data analysis or interpretation. The device appears to be a direct measurement system.

No
The device measures FENO to indicate potential inflammation and treatment response, but it does not directly treat or provide therapy.

Yes

The device measures fractional exhaled nitric oxide (FENO), which is "increased in some airway inflammatory processes, such as asthma," and its measurement is used "as an indication of therapeutic effect in patients with elevated FENO measurements are to be used as an adjunct to established clinical assessments." This indicates its role in identifying or monitoring disease.

No

The device description explicitly states that Fenom Pro is comprised of four major components, including a main unit containing a nitric oxide sensor and pneumatics, a handpiece, and a breath tube, in addition to the software interface. This indicates it is a hardware device with integrated software, not a software-only medical device.

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

Here's why:

  • IVD Definition: IVD devices are used to examine specimens taken from the human body, such as blood, urine, or tissue, to provide information about a person's health.
  • Fenom Pro's Function: The Fenom Pro measures fractional exhaled nitric oxide (FENO) directly from the patient's breath. It does not analyze a specimen taken from the body.

Therefore, while it's a diagnostic tool used in a healthcare setting, it falls outside the typical definition of an IVD.

§ 862.3080 Breath nitric oxide test system.

(a)
Identification. A breath nitric oxide test system is a device intended to measure fractional nitric oxide in human breath. Measurement of changes in fractional nitric oxide concentration in expired breath aids in evaluating an asthma patient's response to anti-inflammatory therapy, as an adjunct to established clinical and laboratory assessments of asthma. A breath nitric oxide test system combines chemiluminescence detection of nitric oxide with a pneumotachograph, display, and dedicated software.(b)
Classification. Class II (special controls). The special control is FDA's guidance entitled “Class II Special Controls Guidance Document: Breath Nitric Oxide Test System.” See § 862.1(d) for the availability of this guidance document.
