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 impacts to productivity.     The app also provides wellness tracking tools, allowing you to log symptoms and personal diary entries. You may share these with healthcare experts and loved ones at your discretion. This app is not intended to diagnose, cure, treat, or prevent any disease or condition. Always consult a healthcare professional before making medical decisions. If you're concerned about your FCV score or any symptoms, please discuss them with your doctor. This product requires an account. Please contact RAIsonance, Inc. support to get started.
