Intended Use
The SonoSentry™ WheezeRate™ Detector is intended to detect and record abnormal breath sounds (continuous adventitious breath sounds/CABS) at the windpipe (trachea), reported as WheezeRate™ in adults and children (2 years and older). WheezeRate™ represents the percentage of abnormal breath sound detected during the measurement time. A licensed health care professional's advice is required to understand the meaning and importance of the SonoSentry™ readings.
Device Description
The SonoSentry™ WheezeRate™ Detector is a hand-held electronic measurement device that utilizes an acoustic contact sensor to acquire, amplify, filter, record and analyze breath sounds at the trachea for the presence of continuous adventitious breath sounds/CABS.

Signal conditioning and digitization PCB - Dedicated DSP . - . SDRAM memory - . Embedded software
More Information

No
The description mentions a "Dedicated DSP" and "Embedded software" for signal conditioning and analysis, but does not explicitly mention AI or ML algorithms being used for the detection or calculation of WheezeRate™. The analysis is described as based on "acoustic contact sensor" data and calculating a percentage of "abnormal breath sound detected," which could be achieved through traditional signal processing techniques.

No
The device is intended to detect and record abnormal breath sounds, providing diagnostic information (WheezeRate™) rather than providing a therapeutic effect.

Yes

The device detects and records abnormal breath sounds and outputs a WheezeRate, which is a measurement used to understand a patient's condition related to breath sounds. The description also mentions that a licensed healthcare professional's advice is required to understand the meaning and importance of the readings, indicating its role in informed medical decision-making.

No

The device description explicitly lists multiple hardware components, including an acoustic contact sensor, microphone, LCD screen, buttons, PCB, DSP, and memory, in addition to embedded software.

Based on the provided information, the SonoSentry™ WheezeRate™ Detector is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, tissue) to provide information for the diagnosis, treatment, or prevention of disease.
  • SonoSentry™ Function: The SonoSentry™ WheezeRate™ Detector works by acquiring, amplifying, filtering, recording, and analyzing breath sounds directly from the patient's trachea using an acoustic sensor. It does not involve the collection or analysis of biological specimens from the body.
  • Method of Operation: The device relies on the physical detection and analysis of sound waves generated by breathing, not on biochemical or cellular analysis of a sample.

Therefore, the SonoSentry™ WheezeRate™ Detector falls under the category of a medical device that performs a physical measurement on the body, rather than an in vitro analysis of a specimen.

Summary of Performance Studies

A clinical study was conducted to ensure that the SonoSentry™ WheezeRate™ Detector can detect and record continuous adventitious breath sounds (CABS), including wheeze, compared to physician assessment of those same breath sounds. Sound files of pediatric and adult study subjects with a previous diagnosis of moderate to severe asthma were analyzed by the SonoSentry and an Expert Panel consisting of Board Certified Pulmonologists. The Multiple Reader/Multiple Case Study demonstrated an acceptable agreement between the output of the SonoSentry and physician detection of CABS.

Summary of Performance Testing – Conclusion

The SonoSentry™ WheezeRate™ Detector and the legally marketed predicate device have the same intended use and technological characteristics. SonoSentry™ was demonstrated to meet the requirements for electrical safety and electromagnetic compatibility as specified in the FDA recognized IEC 60601-1 and IEC 60601-1-2 standards. Bench testing involving the ambient microphone, pressure switch, algorithm, device accuracy, device sensitivity and embedded system demonstrate the performance and functionality of the device and a clinical study demonstrate that the device fulfills its intended use. The SonoSentry™ WheezeRate™ Detector is substantially equivalent to the Personal Wheezometer™, that is, SonoSentry™ is as safe and effective as the legally marketed predicate and does not raise any new types of safety or effectiveness.
