FCV Sentinel is designed to support workforce wellness initiatives by tracking employee health status, and continuously pushing that data to a custom dashboard created for each organization.
The web-based dashboard gives management an early warning that a teammate may be ill, which could affect productivity and project status. With this data, companies can then rapidly respond to potential personnel gaps, and help keep sick employees from coming to work which risks infecting other team members.
When you first use the app, you’ll provide a series of Forced Cough Vocalizations (FCVs) which are really just intentional coughs. The app combines these coughs to establish a matrixed representation of a person’s cough profile, called a Baseline. This baseline is as unique as to each person as their fingerprint.
Then, every time you use the app, you’ll cough again. Each cough generates a new FCV score that compares your current cough to your Baseline. Your FCV score represents the degree of change, or impact, to your FCV profile detected by the product. Your scores are sent to the company dashboard to better track potential staffing issues and impact to productivity.
The app also provides a suite of personal wellness tracking tools, allowing users to input data on a range of symptoms and self-collected vital signs, along with a personal diary.
