What does a change in "FCV Score" mean?

FCV stands for Forced Cough Vocalization – in other words, an intentional cough. This intentional cough is the biomarker that Raisonance technology captures, digitizes, and analyzes using artificial intelligence processed in the Microsoft Azure cloud. 

FCV Sentinel measures changes in a person’s FCV and provides a score to the user each time they use the product. This score represents how much change FCV Sentinel has detected.

To do this, we first have users create a baseline. This is a collection of many coughs which represents a person’s individual FCV profile. This profile is a multi-dimensional imprint of a person’s respiratory system, and is as unique to each person as their fingerprint. 

Once the baseline is established, FCV Sentinel users can cough whenever they’d like to check their FCV status. Each new cough is compared to that person’s baseline, and FCV Sentinel generates a score for each new cough. This score is a measurement of how similar – or different – a person’s current cough is compared to their baseline. 

Everyone’s FCV Scores vary a little bit throughout the day – that is completely normal. Using MyAdvocate will help you see the short and long term trends that reflect your overall respiratory status.
