FCV Sentinel
A personalized early-warning system that tracks your respiratory status over time using only a 10-second cough.
Talk With Us About Sentinel >Most people have no ongoing visibility into their respiratory status. We can check heart rate, activity, sleep, or blood sugar, yet there is still no routine equivalent for knowing whether respiratory health has changed.
That matters because so many things can affect the respiratory system, including viruses, bacterial pathogens, wildfire smoke, indoor air quality, air pollution, chemical agents, environmental toxins, and occupational exposure.
FCV Sentinel keeps an eye on respiratory status and alerts the user when a meaningful change may need attention. It is fast, easy, noninvasive, inexpensive, and customizable for individuals, groups, and organizations.
With regular use, Sentinel replaces the occasional snapshot with continuous, personalized, low-friction monitoring, giving people and organizations more time to respond.
How It Works
To use Sentinel, the user simply coughs for approximately 10 seconds into an Apple or Android smartphone and receives results about 30 seconds later.
No additional hardware or special equipment is required.
Each use captures thousands of data points and acoustic features to track respiratory change over time.
The user gets a personal score and an alert if further evaluation may be appropriate.
Sentinel compares each new cough sample to that user’s completely unique personal baseline. Each new sample provides insight into meaningful changes that might otherwise be gradual, subtle, or easy to overlook.
Use Case
Miners, firefighters, maritime crews, oil and gas workers, factory workers, and other high-risk occupational groups face varied and repeated respiratory exposures in environments where clinic-based monitoring is not always practical.
Sentinel fits this population especially well. It requires no additional hardware or dedicated clinical time, so it can be used as needed rather than being constrained by clinic capacity.
It also creates a defensible, timestamped record of respiratory status over the course of employment, supporting earlier intervention, workforce-health documentation, and compliance readiness.
Use Case
For people managing asthma or COPD, variability over time matters. Respiratory decline is often gradual, easy to normalize, and only acted on when symptoms become severe.
Sentinel offers an objective, continuously updated comparison against each person’s own history. Two people with similar traditional measurements can still have very different personal baselines and early-warning thresholds.
Detecting a meaningful change earlier may give the user more time to adjust treatment, contact a provider, or seek evaluation before the situation becomes more serious.
For Individuals and Organizations
Sentinel provides each user with a personal respiratory score while giving authorized organizations access to broader program visibility, including alerts, trends, group summaries, and KPI reporting.
A high-level dashboard view helps organizations monitor user activity, location trends, and overall participation.
Authorized users can review score history, recovery patterns, and alert activity for individual participants.
Group-level summaries make it easier to compare locations, teams, departments, or units and identify where attention may be needed.
Organizations can connect Sentinel program data to key performance indicators and track trends over time.
