Intended Use
The Salter Labs Oral/Nasal Thermal Airflow Sensor is used as a cannula accessory with existing recording devices and data acquisition systems in a sleep laboratory setting to support the diagnostic recording of nasal and/or oral airflow. The subject device itself performs no diagnostic functions, and only supports the diagnostic recording of airflow for use as an accessory component to a polysomnography recorder. The target population is adult and pediatric patients during a sleep study in a sleep laboratory.
Device Description
The modified device has a minor construction change from that of the predicate device where a series of connected thermocouples replace a series / parallel connection of thermistors. Both elements are placed at the bridge of the nose to measure the same temperature changes during breathing from each nare and from the mouth. The lower cost thermocouples provide a lowcost single-use replacement for the more expensive thermistor device already cleared.
More Information

No
The document explicitly states "Mentions AI, DNN, or ML: Not Found" and describes a simple sensor technology change without any mention of data processing or algorithmic analysis.

No
The device is described as an accessory that supports diagnostic recording of airflow and performs no diagnostic functions itself, indicating it is not a therapeutic device.

No

The text explicitly states, "The subject device itself performs no diagnostic functions, and only supports the diagnostic recording of airflow for use as an accessory component to a polysomnography recorder."

No

The device is a physical sensor (thermocouples) and a cannula accessory, not a software-only device.

Based on the provided text, the Salter Labs Oral/Nasal Thermal Airflow Sensor is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly states it is an "accessory" to existing recording devices and data acquisition systems in a sleep laboratory. Its purpose is to "support the diagnostic recording of nasal and/or oral airflow."
  • Diagnostic Function: The text explicitly states, "The subject device itself performs no diagnostic functions." It only provides data (airflow temperature changes) to a separate diagnostic recording system.
  • Nature of Measurement: It measures temperature changes related to breathing, which is a physiological process occurring in vivo (within the body), not in vitro (outside the body, typically on biological samples).

IVD devices are typically used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. This device does not fit that description.

The thermocouple device functions in the same manner as does the predicate device and that is it detects changes in temperature, corresponding to an exhalation and inhalation of the patient. The goal here is to determine rate of respiration for sleep lab studies.

Description of the test set, sample size, data source, and annotation protocol

Clinical Testing was simply down to show that the Thermocouple device was not only sensitive enough to provide an adequate signal on the Test Fixture (which includes a Polysomnograph system) but that it was sensitive and timely enough to record a substantial signal compared to that of other physiological respiratory events.

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

Clinical Testing was simply down to show that the Thermocouple device was not only sensitive enough to provide an adequate signal on the Test Fixture (which includes a Polysomnograph system) but that it was sensitive and timely enough to record a substantial signal compared to that of other physiological respiratory events. Clinically, the device adds no additional adverse effects or complications as did the predicate device, primarily because their structure is similar and both fit in properly designed cannulas.

    The modified device has a minor construction change from that of the predicate device where a series of connected thermocouples replace a series / parallel connection of thermistors.

The the mocouple device functions in the same manner as does the predicate device and that is it detects changes in temperature, corresponding to an exhalation and inhalation of the patient. The goal here is to determine rate of respiration for sleep lab studies.

  • Scientific concept . The scientific concept governing the Thermocouple is called the "Seebeck Effect".
  • Physical & Performance characteristics (device design, material used, .
  • properties)

Physically, both devices are small enough to be placed directly in the path of the air stream of the nares and mouth.

From a performance standpoint, where the Thermistor required an interface box to energize the changed resistance to provide a signal, the Thermocouple self-generates a microvolt signal by having dissimilar materials.

· Intended Use:

The Salter Labs Oral/Nasali Thermal Airflow Sensor is used as a cannula ' accessory with existing recording devices and data acquisition systems in a sleep laboratory setting to support the diagnostic recording of nasal and/or oraliairflow. The subject device itself performs no diagnostic functions, and only supports the diagnostic recording of airflow for use as an accessory component to a polysomnography recorder. The target population is adult and pediatric patients during a sleep study in a sleep laboratory.

  • Technological Characteristics compared to predicate device The predicate device is a "thermal resistive element" and the Thermocouple. is a "Thermal Electric device". Both devices can be said to be a "Thermal responsive device", wherein "RTD" would fall into this category.
