FCV Sentinel — Frequently Asked Questions

FCV Sentinel is designed to support team wellness initiatives by tracking team member health status, tracking fitness and performance while continuously pushing that data to a custom dashboard created for each team.

The web-based dashboard gives team management an early warning that a teammate may be ill, which could affect productivity and project status. With this data, teams can then rapidly respond to potential personnel gaps and help keep sick team members from coming to events, training and practices which risks infecting other team members.

When you first use the app, you'll provide a series of Forced Cough Vocalizations (FCV) 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 team dashboard to better track potential wellness issues and impacts to performance.

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.

Here are some step-by-step instructions:

1. Install and launch the FCV Sentinel app
2. Input the Email & Password provided by your team's administrator or HR Department into the Log In fields
3. Toggle the check box to accept the FCV Sentinel Terms of Use
4. Click "Login"
5. Review the information that is displayed in the Profile screen. (If any of the information is incorrect, please contact your organization's administrator to update your profile.)
6. Click "Next"
7. Input a response to the question on the "Additional Information" screen, then click "Save & Next".
8. The following screen will require that you take or upload a Profile Picture. Ensure that you upload a well-lit, clear picture of your face that does not include anyone else in the photo. Then, click "Save & Next".
9. Lastly, click "Build Your Baseline" on the resulting screen to record your unique Baseline Forced Cough Vocalization (FCV). FCV Sentinel will take you through a mini tutorial to help you set up your Baseline.

The FCV Sentinel app requires each user to set what is referred to as a "Baseline". This is a process where each user teaches the FCV Sentinel app to recognize their unique Forced Cough Vocalization (FCV), otherwise known as an intentional cough.

To do this, the FCV Sentinel app guides you through a simple process of providing these cough samples. Please refer to the guide below:

FCV Sentinel Baseline Process:
The app requires 30 approved cough samples to set your Baseline. We ask you to cough 12-14 times per sample set, so you'll likely need to complete at least 4 separate Baseline Cough sets in order to complete your Baseline. Note that after you do a Baseline cough you'll be forced into a minimum 2-hr forced break between samples.

• Step 1: FCV Sentinel will ask you to record your first Baseline cough sample set with 12-14 coughs.
• Step 2: After you've done Baseline Cough Set #1, FCV Sentinel will tell you to take a break and come back in 2 hours to record more samples. This is to rest your voice and respiratory system.
• Step 3: After the 2-hour rest, you may resume providing your Baseline cough sample sets. After each set, FCV Sentinel will pause you once again with a 2-hr forced break to rest your voice and respiratory system.
• Step 4: Once you've completed 4 Baseline cough sample sets, the app will calculate your coughs from those sets. If you have 30 or more, you'll be all done! If you haven't quite reached that 30 acceptable cough mark yet, the app will ask you for another Baseline cough sample set up until you reach the 30 approved cough samples.

Here are a couple possible solutions...

Problem 1: You're receiving an "Oops!" result
If you are receiving an error screen saying, "Oops! There was an error with your recording. Make sure you're in a quiet space and try again." while submitting your Baseline, please refer to some potential solutions below.

Potential Solutions:

1. Be sure you are in a quiet place when you re-record. A lot of background noise in your recording, such as talking, music, machinery, etc. can make it difficult for the FCV Sentinel app to collect the recording needed.
2. Be sure you are not coughing too close to the microphone on your phone. Coughing too close can actually garble the sound. Instead, keep the phone at least 12 inches away from your mouth when you record.
3. Be sure that you're only submitting a series of 12-14 individual coughs before clicking to submit your coughs. If you provide a sound other than your coughs, such as talking or laughing during your recording, it will confuse the FCV Sentinel app. In these cases, you will receive an error message that says "Oops! There was an error with your recording. Make sure you're in a quiet space and try again."

Problem 2: You're receiving a "We need a bit more..." or "Almost there!" result
If you are receiving a result screen saying, "We need a bit more..." or "Almost there!" while submitting your Baseline coughs, this simply means that the FCV Sentinel app requires a few more sample coughs from you to accurately complete your Baseline cough model. Please refer to some potential solutions below.

Potential Solutions:

1. Be sure you are in a quiet place when you re-record. A lot of background noise in your recording, such as talking, music, machinery, etc. can make it difficult for the FCV Sentinel app to collect the recording needed.

There was an error with your recording. Make sure you're in a quiet space and try again."

Once you've checked to make sure you're following the above recommendations, simply click "Next" and submit the next set of coughs that the app is requesting.

Once you've set up your Baseline, you are free to start using the FCV Sentinel app as often as you wish with just one limitation. For more information about the FCV Score that results from an FCV Check, please see the FAQ "What does my FCV Score mean?"

Note:
The FCV Sentinel app is designed so that you don't FCV Check more frequently than every 30 minutes. This is simply to ensure that you don't fatigue your vocal cords by submitting a FCV Check too frequently.

When trying to complete a FCV Check, you may receive a timer screen indicating that you must wait the indicated amount of time before completing another FCV Check. Not-to-worry — in the case in which you've tried multiple times to complete a FCV Check, but received an "Oops!" result screen at least 3 times, you'll be asked to wait 30 minutes before re-attempting. This is simply to ensure that you don't fatigue your vocal cords by submitting a FCV Check too frequently.

After setting your initial FCV Baseline, users can come back to complete a "FCV Check" of their FCV up to every 30 minutes.

Also, after setting an initial Baseline, users are free — and encouraged to — track symptoms/vital signs with the symptom/vitals tracker feature. This feature provides a fast, easy way to track bothersome symptoms that you may experience if your wellness is impacted by illness. The diary feature allows users to document more granular thoughts, feelings and discoveries in their own words to refer back to at any time.

This mobile tracker does not diagnose, cure, treat, or prevent any disease or condition.

You can complete a FCV Check of your Forced Cough Vocalization (FCV) as often as every 30 minutes. For more information about the FCV Score that results from a FCV Check, please see FAQ "What does my 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.

The human respiratory system is the network of organs and tissues that allow us to breathe by helping the body absorb oxygen from the air and clean waste gases like carbon dioxide from the blood. The airways, consisting of the mouth and nose, sinuses, throat, trachea, and bronchial tubes deliver air to the lungs, extract oxygen from the air and move it to the bloodstream. The bloodstream delivers oxygen to all the organs and tissues of the body.

All humans have mucus throughout their airways. This mucus lines the epithelial surfaces (the cells that line the internal and external surfaces of the body) of the respiratory system. These surfaces are continuously exposed to the outside environment by breathing, eating, and speaking. This airway mucus changes in reaction to certain stimuli, such as illness, environmental toxins, and chemical agents.

Respiratory changes are a measurable biomarker that is tracked by FCV Sentinel during the physical activity of Forced Cough Vocalization (FCV).

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 FCV Sentinel will help you see the short- and long-term trends that reflect your overall respiratory status.

The primary defense used by our bodies' respiratory system is the secretion and clearance of mucus. Over time, humans evolved specialized methods to protect itself from airborne environmental hazards, pathogens, viruses, and the like. Irritation of the respiratory tract causes changes in blood flow, mucus secretion, and diameter of a person's airway.

Toxins can interact with secretions directly and can change the nature of the mucus, while other nerves and sensory receptors in the body react to lung irritation or pulmonary (lung) inflammation. This inflammation changes many aspects of a person's cough. Sometimes these changes are identified by skilled medical professionals simply by listening to a person's cough. But often these changes are so subtle that sophisticated artificial intelligence is better suited to identifying and scoring the severity of those changes. Each of these responses to irritants changes the frequency and energy pattern of a person's FCV. Repeated or prolonged exposures to irritating gases, vapors, pathogens, and fumes can lead to the development of irritant-induced changes in the FCV.

Studies show that trackable information offers invaluable support during the difficult process of smoking cessation.

Currently, the FCV Sentinel app is for use by adult-sized persons age 16+. As we gain experience with persons less than 4 feet tall, we anticipate maintaining the same level of accuracy for FCV Checks.

There could be several reasons why you're receiving an error result. These reasons include:

• Accidentally covering the microphone with a thumb or finger
• Holding the phone too close to your mouth (closer than 12 inches)
• Leaving a great deal of silence before and after your cough in your recording
• Talking, laughing or having other background noise present

Additional Resources:

• Baseline Issues: If you're encountering an error screen when setting your Baseline, see FAQ "I'm having trouble creating my baseline" for help resolving the issue.
• FCV Check Issues: If you're encountering an error screen when attempting to complete a FCV Check, see FAQ "I am having trouble completing my FCV Check" for help resolving the issue.

Since we use Forced Cough Vocalization (FCV) sound signatures, if your voice changes for any reason, your ability to complete a FCV Check may be affected. If these changes are permanent (i.e., growth, surgery, etc.), it will be necessary to repeat the Baseline setting process.

In these isolated cases, please contact customer service to help you address the matter.
