Intended Use
The tremoFlo C-100 Airwave Oscillometry System is intended to measure respiratory system impedance using the Forced Oscillation Technique (FOT). tremoFlo C-100 Airwave Oscillometry System is intended for use with pediatric and adult patients 4 years of age or older. The device is designed to be used by pulmonologists, general practitioners, nurses, respiratory therapists, laboratory technologists, medical researchers and similarly trained personnel in hospitals, clinics, and private physician offices.
Device Description
The tremoFlo C-100 Airwave Oscillometry System (AOS) is a portable lung function testing device that implements methods known per the Forced Oscillation Technique (FOT) to assess lung function in humans. The Forced Oscillation Technique (FOT) is a non-invasive test that requires minimal patient effort and cooperation and provides a full report of lung mechanics per the FOT. In general, the FOT usually consists of superimposing given external multi-frequency sinusoidal excitation small pressure waves (1-3 cmH2O peak to peak) onto the normal breathing of the patient through the device and then deriving the mechanical properties from the patient's mouth pressure and airflow response while breathing. The main outcome reported by FOT is the mechanical impedance of the respiratory system which is the complex ratio between pressure and airflow at the given excitation frequencies. The tremoFlo C-100 Unit is a lightweight handheld device connected to a cradle unit. The handheld unit contains electronics, pressure and flow sensors, and the actuator providing the forced oscillations which is connected to the cradle unit via a custom cable. The tremoFlo software is a complete stand-alone software package for patient management, testing, and result analysis and presentation.
More Information

No
The summary describes a device using the Forced Oscillation Technique (FOT) to measure respiratory impedance. It details hardware components, software for data management and analysis, and standard performance and safety testing. There is no mention of AI, ML, or related concepts like training/test sets, image processing, or specific AI/ML metrics.

No.
The device is intended to measure respiratory system impedance and assess lung function, not to treat a medical condition.

Yes
The device is described as a "portable lung function testing device" that assesses lung function and provides a "full report of lung mechanics," which are used to derive "mechanical properties" from pressure and airflow response. This information is used to evaluate the state of the respiratory system, indicating a diagnostic purpose.

No

The device description explicitly states that the tremoFlo C-100 Airwave Oscillometry System includes a "lightweight handheld device connected to a cradle unit" which contains "electronics, pressure and flow sensors, and the actuator providing the forced oscillations." This indicates the presence of physical hardware components beyond just software. The summary also mentions "Hardware performance validation tests" and "Electrical safety and Electromagnetic Compatibility" testing, further confirming it is not a software-only device.

Based on the provided information, the tremoFlo C-100 Airwave Oscillometry System is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • Intended Use: The intended use is to "measure respiratory system impedance using the Forced Oscillation Technique (FOT)." This is a measurement of a physiological function within the body, not an analysis of a sample taken from the body.
  • Device Description: The device works by applying pressure waves to the patient's breathing and measuring the response. This is a direct interaction with the patient's respiratory system, not the testing of a biological sample.
  • Lack of Sample Analysis: The description does not mention the collection or analysis of any biological samples (like blood, urine, tissue, etc.), which is a defining characteristic of IVD devices.

IVD devices are specifically designed to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. The tremoFlo C-100 measures a physical property of the respiratory system in vivo.

The tremoFlo software is a complete stand-alone software package for patient management, testing, and result analysis and presentation.

The tremoFlo C-100 system is easy to transport within a busy clinic or hospital environment. During use the operator holds the handheld device using the ergonomic handle while the patient is seated, wearing a standard nose clip and with hands on cheeks breathes quietly through the device into a standard single use Pulmonary Function Testing (PFT) filter connected at the front of the handheld unit via the PFT filter interface. Like its predicate the tremoFlo is not intended to be used as a stand-alone diagnostic device.
