No
The summary describes a sensor that uses ultrasonic technology to measure flow rate, with no mention of AI or ML in the device description, intended use, or performance studies.
No
This device is for measuring respiratory flow rate (diagnostic/monitoring function), not for treating a condition.
No
The device measures a physiological parameter (respiratory flow rate) but is not indicated for diagnosing any specific condition. It's a monitoring device rather than a diagnostic one.
No
The device description explicitly states it is a "Narkomed Ultrasonic Flow Sensor" which "mounts to the expiratory valve fitting" and "ultrasonically measures respiratory flow rate." This describes a physical hardware component, not a software-only device.
Based on the provided information, the Narkomed Ultrasonic Flow Sensor is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to measure the respiratory flow rate of gas through the patient breathing circuit. This is a measurement of a physiological process happening in vivo (within the living patient's respiratory system), not a test performed in vitro (outside the body, on samples like blood, urine, or tissue).
- Device Description: The device mounts to the expiratory valve fitting and measures flow ultrasonically. This further reinforces its function as a direct measurement of gas flow within the breathing circuit connected to the patient.
- Lack of IVD Characteristics: The description does not mention analyzing biological samples, detecting substances in samples, or providing information about a patient's health status based on laboratory analysis of samples.
Therefore, the Narkomed Ultrasonic Flow Sensor is a medical device used for monitoring a physiological parameter during anesthesia, not an in vitro diagnostic device.

Intended Use / Indications for Use
The Narkomed Ultrasonic Flow Sensor is intended for measuring the flow rate of gas through the patient breathing circuit to determine tidal volume, minute volume, and respiratory rate.
The Narkomed Ultrasonic Flow Sensor is indicated for measuring the respiratory flow rate of gas through the patient breathing circuit. Federal law restricts this device to sale by or on the order of a physician.

§ 868.5160 Gas machine for anesthesia or analgesia.
(a)
Gas machine for anesthesia —(1)Identification. A gas machine for anesthesia is a device used to administer to a patient, continuously or intermittently, a general inhalation anesthetic and to maintain a patient's ventilation. The device may include a gas flowmeter, vaporizer, ventilator, breathing circuit with bag, and emergency air supply.(2)
Classification. Class II (performance standards).(b)
Gas machine for analgesia —(1)Identification. A gas machine for analgesia is a device used to administer to a patient an analgesic agent, such as a nitrous oxide-oxygen mixture (maximum concentration of 70 percent nitrous oxide).(2)

Summary of Safety and Effectiveness Data Relating to Substantial Equivalence
Proprietary Name: Narkomed Ultrasonic Flow Sensor
Classification Name: Monitoring Spirometer
Class II Device Class:
North American Dräger Manufacturer: 3135 Quarry Road Telford, Pennsylvania 18969
Establishment Registration Number: 2517967
Devices to which substantial equivalence is claimed: Spiromed 2 K851620
Device Description:
The Narkomed Ultrasonic Flow Sensor mounts to the expiratory valve fitting on Narkomed Anesthesia Systems and ultrasonically measures respiratory flow rate.
Intended Use:
The Narkomed Ultrasonic Flow Sensor is intended for measuring the flow rate of gas through the patient breathing circuit to determine tidal volume, minute volume, and respiratory rate.
Substantial Equivalence:
The Narkomed Ultrasonic Flow Sensor is substantially equivalent to the Spiromed 2.
The Narkomed Ultrasonic Flow Sensor and the Spiromed 2 have the same intended use. The principle of operation of the Narkomed Ultrasonic Flow Sensor differs in that it measures ultrasonic pulses while the Spiromed 2 measures electronic pulses generated by positive displacement. There have been no new questions of safety and efficacy raised as a result of the Narkomed Ultrasonic Flow Sensor technology. Therefore the Narkomed Ultrasonic Flow Sensor and the Spiromed 2 are substantially equivalent.
Qualification of the Narkomed Ultrasonic Flow Sensor included a hazard analysis, functional and communication testing, environmental testing, and electromagnetic compatibility testing.

Re: K974193 Narkomed Ultrasonic Flow Sensor Regulatory Class: II (two) Product Code: 73 BSZ November 6, 1997 Dated: November 7, 1997 Received:
Dear Mr. Brennan:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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). 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.
If your device is classified (see above) into either class II ($pecial Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. - Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations. "
