G7 App Essentials

This shows the most important things you need to know to use the Dexcom app. For receiver instructions, open the receiver box.

Screen overview

Glucose information
The Glucose tab shows your current sensor reading and trend information. Tabs at the bottom of the screen move you to other sections. Each tab has information grouped into cards.
The following screen shows all the features on the Glucose tab’s first card:

1. Number: The most recent sensor reading. Shows LOW if below 40 mg/dL or HIGH if above 400 mg/dL.
2. Trend arrow: Where glucose is heading based on the last few readings.
3. Shortcut to add event so you can quickly track insulin doses, meals, exercise, and BG meter values. If you choose to calibrate, you do that here.
4. 3 Hours, 6, 12, 24: Change the number of hours shown on the trend graph.
5. The three dots is the More button. It gives you quick access to change alert levels and choose a Quiet Mode.
6. Trend graph: The bigger dot on the right is the most recent sensor reading. The smaller dots show past readings.
7. Target range (shaded rectangle inside graph): 70–180 mg/dL is the international consensus for recommended target range. Change the target range in Profile > Glucose Tab
8. High alert yellow line: You get your High alert when your glucose is at or above this yellow line.
9. Low alert red line: You get your Low alert when your glucose is at or below this red line.
   Change alert settings in Profile > Alerts

Sensor reading and trend arrow

Where your glucose is now
On the Glucose tab, your sensor reading shows a number and color. They tell you where your glucose is now.
Number: The most recent sensor reading. It updates every 5 minutes.
Color: Shows whether your sensor reading is low, high, or between.

• White: Between your High and Low alert levels
• Yellow: High
• Red: Low, Urgent Low Soon, or Urgent Low

Sensor reading issues
Sometimes you don’t get a number. If you don’t have a number, or you don’t have an arrow, use your BG meter to treat. Go to the Treatment Decisions section for more information. System alerts mean G7 isn’t working. You won’t get sensor readings or glucose alerts. Go to System Alerts section for more information.

Where your glucose is going
To know where your glucose is heading, look at your trend arrows

Steady: Changing less than 30 mg/dL in 30 minutes

Slowly rising or falling: Changing 30–60 mg/dL in 30 minutes

Rising or falling: Changing 60–90 mg/dL in 30 minutes

Rapidly rising or falling: Changing more than 90 mg/dL in 30 minutes

No arrow: Can’t determine trend; use BG meter for treatment decisions For more information, review the instructions and videos at Profile > Help > How To

Navigation

You can access other features using the navigation icons.

Glucose tab: Clarity card
Scroll down in the Glucose tab to see the card below the trend graph. It has your Clarity glucose summary reports. The 3, 7, 14, 30, and 90-day reports show how your glucose changes over time using the information recorded in the app. When you scroll down on your screen, you still see a small version of your current sensor reading and trend arrow at the top of the screen.

History, Connections, and Profile Tabs
Use the tabs at the bottom of the screen to get to other features. The Glucose tab is described in the previous section. History, Connections, Profile, and the Profile Help menu are described below.

• History: Go here to see your events log and track your BG meter values, meals, insulin (long and fast acting), and activity. You can also take notes. If you choose to calibrate, you do that here.
• Connections: Go here to get information on your sensor, see your pairing code, and end your sensor session. You can also share your glucose information with friends and family and send glucose data to Apple Health.
• Profile: Here you can change settings and get help.
• Profile > Help: Find help, including links to product guides and videos on inserting and removing sensors, sensor readings, alerts, and when to use your BG meter.

Treatment Decisions

When to use your BG meter instead of G7
You can use your G7 to treat. However, there are two situations when you should use your BG meter instead:

• No number and/or no arrow: When you have no sensor reading, or no trendarrow, or have a system alert, use your BG meter to treat.
• Symptoms don’t match sensor readings: When how you feel doesn’t match your sensor reading, use your BG meter to treat even if you have a number and arrow. In other words, when in doubt, get your BG meter out. For example, you don’t feel good, but your sensor readings show you’re in range. Wash your hands thoroughly and use your BG meter. If the BG meter value matches your symptoms, use the BG meter value to treat.

When to watch and wait
Don’t stack insulin by taking doses too close together. Talk to your healthcare provider about the right amount of time for you to wait between doses so you don’t accidentally force your glucose down too low. This is different from taking insulin doses to cover what you just ate.

Using the trend arrows
Talk to your healthcare provider about using the trend arrows to determine how much insulin to take. Consider taking a little more insulin than usual when your glucose is rising. Consider taking a little less insulin than usual when your glucose is falling.

Treat with professional advice
Confirm with your healthcare provider about using G7 to manage your glucose, setting alert levels, comparing BG meter values and sensor readings, and fingerstick best practices.

Practice making treatment decisions
Use the following situations as examples of times when G7 could be used when treating. These situations are just examples, not medical advice. You should discuss your treatment and these examples with your healthcare provider and review how you can use your G7, when to watch and wait instead of treat, and when you need to use your BG meter. You should keep using your BG meter until you’re comfortable with G7.

Situation: Early morning

Your Low alert wakes you up.
Think about:

• Number and Arrow: You have both
• Number: Your glucose is 70 mg/dL, which is low
• Arrow: Glucose is slowly falling 30–60 mg/dL in 30 minutes

What you should do:

• Use your G7 to treat as you normally would

Situation: Breakfast time

Ninety minutes later you sit down for breakfast.
Think about:

• Number and Arrow: You have both
• Arrow: Glucose is rising up to 60–90 mg/dL in 30 minutes

What you should do:

• Use your G7 to treat. Take your normal dose and, because of the up arrow, consider taking a little more.

Situation: After breakfast

Thirty minutes after dosing to cover breakfast, you get a High alert. 221 mg/dL

Think about:

• Insulin: You took insulin half an hour ago. It takes time to work.
  What you should do:

• Nothing. Watch and wait to avoid stacking insulin.
  The insulin you took 30 minutes ago is probably just starting to work. Unless your heathcare provider told you differently, track your glucose level for the next hour or two. The insulin you already took should decrease your glucose level in that time.

Situation: An hour later You watched and waited. 117 mg/dL

Think about:

• Insulin: The insulin you took with breakfast has you back in range

What you should do:

• Nothing. No treatment needed.

Situation: Lunch time

Three hours later, you’re about to dose for lunch.

Think about:

• Number and Arrow: You have both
• Arrow: Your glucose is falling between 60–90 mg/dL in 30 minutes

What you should do:

• Use your G7 to treat. Because the down arrow shows your glucose is falling, consider taking a little less insulin than usual.

Situation: Early evening

Just before dinner, you feel a little shaky and sweaty.

Think about:

• Symptoms and Sensor Reading: Your symptoms don’t match your sensor readings

What you should do:

• Thoroughly wash your hands and take a fingerstick. If your BG meter value matches your symptoms, use it for treatment decisions.

Alerts

Your glucose alerts help you stay in your preferred range. They display on your screen, make a sound, and/or vibrate when your glucose is out of your preferred range, is at or below 55 mg/dL, or will be at 55 mg/dL in less than 20 minutes. Additionally, you can turn on your Rising Fast or Falling Fast alerts so you’ll know when your glucose is rising or falling quickly. You can customize each of these alerts in Profile > Alerts. For more information on customizing alerts, go to the Changing Alerts section. Work with your healthcare provider to customize your alerts to fit your lifestyle and goals.

Phone Safety

These phone settings stop your alerts and app from working:

• Apple features include: Screen Time and Low Power Mode
• Android features include: Focus Mode, App Pause, and Battery Saver Mode
  For more information go to Profile > G7 iPhone Safety or Profile > G7 Android Safety

Glucose alerts

• Urgent Low alert: Alerts you when your sensor reading is 55 mg/dL or below.
• Urgent Low Soon alert: Alerts you when your sensor reading will be 55 mg/dL or below in less than 20 minutes.
• Low Glucose alert (Low): Alerts you when your sensor reading is at or below the level you set. It’s the red line on the trend graph.
• High Glucose alert (High): Alerts you when your sensor reading is at or above the set level. It’s the yellow line on the trend graph.

System alerts
System alerts let you know if the system isn’t working as planned. When possible, the alert lets you know how to fix it.System alerts: Alerts not related to your glucose, including technical alerts. System alerts include: App Bluetooth is Off, App is closed, App Location is Off, App Stopped Working, App Stopped: Phone Storage Full, Brief Sensor Issue, Cannot pair sensor, Pairing Unsuccessful, Phone Bluetooth is Off, Phone Location is Off, Phone Storage Low, Phone Storage Very Low,Readings Stop Soon, Replace Sensor Now, Sensor Expired, Sensor Expires in 2 Hours, Sensor Expires in 24 Hours, Sensor Failed, Sensor not found yet, Sensor Paired, Sensor Warmup Complete, Set Date/Time, Signal Loss, System Check.

Technical alerts: These alerts are a subset of system alerts. Technical alerts are  aboutsituations that prevent, or will prevent, your current glucose information from displaying. If you don’t acknowledge a technical alert, it will add sound. Technical alerts include: App Stopped Working, App Stopped: Phone Storage Full, Brief Sensor Issue, Replace Sensor Now, Sensor Failed, Signal Loss.

Responding to alerts
When you get an alert, your first priority is to resolve it: make a treatment decision or fix a system issue. Afterward, acknowledge the alert on your display device by tapping OK on the alert. Until you acknowledge the alert, it re-alerts every 5 minutes. You can also acknowledge an alert from your Lock screen by following these instructions:

• iPhone: There are two ways to acknowledge alerts from your Lock screen. First, from the Lock screen, touch and hold the notification until a second OK appears. Tap that OK to acknowledge the alert. Or second, tap the Lock screen notification to open the app. From the app, tap OK on the alert to acknowledge it. (If you tap Dismiss instead of following the instructions above, the alert will re-alert in 5 minutes.)
• Android: There are three ways to acknowledge alerts from your Lock screen: First, if your notification has an OK button, tap OK to acknowledge the alert. Or second, if your notification doesn’t have an OK button, pull down on the notification and tap OK to acknowledge the alert. Or third, tap the notification (not the OK button) to open the app. Then tap OK to acknowledge the alert.
• Smartwatch: On your smartwatch Lock screen, tap OK to acknowledge the alert. That will also acknowledge the alert in your app.

Alert vibrations feel the same as notifications you get from other apps on your smart devices. The only way to know if it’s from your G7 is to look at your smart device.

Changing alerts

Profile > Alerts shows all the alerts you can change. Tap each one to find out how to change it.

Vibrate
Quiet Modes: Quickly change all your alerts to be more discreet. Quiet Modes override your phone sound setting and each alert’s Sound/Vibrate setting. You still see alerts on your phone’s lock screen and in the app.

l Vibrate:

• All alerts vibrate but won’t sound. You can set vibrate mode for up to 6 hours or indefinitely.
• Vibrate Exceptions: (these exceptions always apply, not just in Quiet Mode)
• Your phone vibrate setting must be on for the alerts to vibrate. For more information, go to Profile > G7 iPhone Safety or Profile > G7 Android Safety
• Urgent Low and technical alerts act differently; if you don’t acknowledge them, they will add sound. In the app, these alerts include: Urgent Low, App Bluetooth is Off, App is Closed, App Location is Off, App Stopped: Phone Storage Full, App Stopped Working, Phone Bluetooth is Off, Phone Location is Off, Replace Sensor Now, Sensor Failed

Next Sensor Session

Each sensor session lasts up to 10 days, plus a 12-hour grace period at the end. The grace period gives you more time to replace your sensor so you can do it when it’s convenient for you. The time left in the grace period shows on your screen. During the grace period, your sensor continues to work as it did during the sensor session. You’ll get alerts letting you know your sensor session or grace period will end soon. You can choose to wear the sensor until the grace period ends or end the session early. To end your session early, go to Connections > Sensor and follow the instructions on the screens. You only need to end your sensor session on one display device.

Troubleshooting

For more troubleshooting information, see the frequently asked questions section on theDexcom website (dexcom.com/faqs), or contact technical support (in the app, go to Profile > Contact).

Adhesive patch
Issue: Skin irritation around sensor site.

Solution

Some people are sensitive to the sensor adhesive. Extra care can help. Follow insertion instructions carefully. In addition to the site preparation tips above, consider these:

• New site: Don’t use the same sensor site twice in a row.
• Healthy skin : Consider moisturizing skin between sensor sessions to avoid dry skin. Don’t use moisturizer on the sensor site the day you insert the sensor.

Solution:
Check the G7 Safety Information-Check Settings section as well as the following:

• Phone is on: Verify that the app, Bluetooth, sound, and notifications are on, and the volume is loud enough for you to hear it. App is on when it’s open and/or running in the background. Swiping up on the app in preview closes it.
• Phone settings:
• Fix any phone setting issues the app alerts you about
• These phone settings stop your alerts and app from working:
• Apple features include: Screen Time and Low Power Mode
• Android features include: Focus Mode, App Pause, and Battery Saver Mode
• For more information, go to Profile > G7 iPhone Safety or Profile > G7 Android Safety
• Phone operating system: Automatic updates of the app or your device operating system can change settings or shut down the app. Update manually, and verify correct device settings afterward. Before upgrading your smart device or its operating system, check dexcom.com/compatibility.
• Alert settings: Make sure you use sounds that you can hear for each alert. For more information, go to the Alerts chapter in the online User Guide.
• Quiet Modes: Make sure you aren’t using Vibrate. For more information, go to the Changing Alerts section.
• Second Alert Profile: Check Schedule to make sure you’re using the alert profile you expect. For more information, go to the Alerts chapter of the online User Guide.

Safety Information

Important user information
Read the indications, warnings, precautions, and instructions for your G7. If you don’t, you may have inaccurate sensor readings, missed alerts, and might miss a severe low or high glucose event. Getting familiar with G7 could take days, weeks, or even months.

Indications for use
The Dexcom G7 Continuous Glucose Monitoring System (Dexcom G7 CGM System or G7) is a real time, continuous glucose monitoring device indicated for the management ofdiabetes in persons 2 years and older. The Dexcom G7 CGM System is intended to replace fingerstick BG testing for diabetes treat ent decisions. Interpretation of the Dexcom G7 CGM System resultsshould be based on the glucose trends and several sequential sensor readings over time. The Dexcom G7 CGM System also aids in the detection of episodes  ofhyperglycemia and hypoglycemia, facilitating both acute and long-term therapy adjustments. The Dexcom G7 CGM System is also intended to autonomously communicate with digitally connected devices, including automated insulin dosing (AID) systems. The Dexco  G7 CGM System can be used alone or in conjunction with these digitally connected medical devices for the purpose of managing diabetes.

Contraindications

No MRI/CT/diathermy — MR unsafe: Don’t wear any Dexcom G7 CGM System component during magnetic resonance imaging (MRI) or high-frequency electrical heat (diathermy) treatment. However, it’s safe to have a CT scan if you keep the sensor out of the scanned area and cover the sensor with a lead apron during the scan.

Warnings
Read product instructions before you use your Dexcom G7 CGM System
Don’t ignore low/high symptoms: Use your BG meter to make treatment decisions when your sensor readings don’t match your low/high symptoms. If needed, seek immediate medical attention.
No number, no arrow, no CGM treatment decision: Use your BG meter to make treatment decisions when your Dexcom G7 CGM System doesn’t show both a number and trend arrow as well as during the 30-minute sensor warmup period. Don’t use if you are pregnant, on dialysis, or critically ill: The Dexcom G7 CGM System performance hasn’t been evaluated in these populations and sensor readings may be inaccurate.
Sensor wire breaks off: Don’t ignore broken or detached sensor wires. If this happens, please contact 24/7 technical support (in the app, go to Profile

Contact). If a sensor wire breaks off or detaches under your skin and you can’t see it, don’t try to remove it. Contact your healthcare provider if you have symptoms of infection or inflammation — redness, swelling, or pain — at the insertion site.
Where to insert — arm or buttocks: Don’t wear it on other sites as it may not work as expected. If you wore G6 sensors on your abdomen, wear G7 sensors on the back of your upper arm. Children from 2 to 6 years old can also choose their upper buttocks.
Where to store: You can store your sensors at room temperature or in your refrigerator, between 36° F and 86° F, but not in the freezer. Inspect: Don’t use any damaged or cracked Dexcom G7 CGM System component because it may not work correctly and could cause injuries from electrical shocks.
Use as directed: The Dexcom G7 CGM System is small and may pose a choking hazard if swallowed.

Bluetooth: Make sure your Bluetooth is on. If not, you won’t get readings or alerts. Notifications:

• Make sure your smart device settings follow Dexcom’s recommended settings. Certain phone settings such as Android’s Digital Wellbeing and Apple’s Screen Time may prevent notifications if enabled.
• Allow Dexcom G7 CGM System app notifications to show on your Lock screen. This will ensure you receive Dexcom notifications and allow you to see notifications without unlocking your phone.
• Android users must allow Location Permission, Do Not Disturb Access, and Notifications to use the app.
• Apple users must allow Critical Alerts to use the app.

Compatibility: Before upgrading your smart device or its operating system, check dexcom.com/compatibility. Automatic updates of the app or your device operating system can change settings or shut down the app. Always update manually and verify correct device settings afterward. While connected to the internet, the app checks periodically and will display a message if it’s not compatible (or no longer compatible) with your phone or your phone’s operating system (OS). The message may include a timeframe for updates.

Time: Let the date and time on your smart device automatically update when you travel across time zones or switch between standard and daylight saving times. Don’t manually change your smart device time because you may not get readings or alerts and it may make the time on the trend screen wrong.

Use electrical equipment as directed:

Use of accessories, cables, adapters, and chargers other than those specified or provided by the manufacturer of this equipment could result in increased electromagnetic emissions or decreased electromagnetic immunity of this equipment and result in improper operation.

Precautions

Secure internet: Only use a cellular internet connection, a trusted Wi-Fi network (like your home or office), or use a secure internet connection such as a VPN service when using your G7 system. Don’t use unsecured public Wi-Fi such as guest networks in other’s homes, restaurants, schools, libraries, hotels, airports, airplanes, etc. Those could expose your G7 system to viruses or hacking.

Check accessories: When using accessories such as headphones, Bluetooth speakers, or smartwatches, you may get your alerts on only one, not all. After connecting any accessories, make sure that your smart device settings allow you to continue receiving alerts.

Clean and dry skin: If your insertion site and hands aren’t clean and dry, you run the risk of infection and the sensor not sticking well. Clean your insertion site with alcohol wipes to prevent infections. Before insertion and during your sensor session, don’t apply insect repellent, sunscreen, perfume, or lotion on your insertion site or sensor. This may cause the sensor to not stick well or could damage your Dexcom G7 CGM System. Be accurate, be quick: If you calibrate your Dexcom G7 CGM System using your BG meter, enter the BG value on your meter within five minutes of measuring your BG.

Use fingertips: Use a BG sample from your fingertips when calibrating as blood glucose from other places may be less accurate and not as timely. Calibration is not required but you can do optional BG calibration to align with your meter.

Change your insertion site with each sensor to allow the skin to heal. Avoid areas:

• With loose skin or without enough fat to avoid muscles and bones.
•  That get bumped, pushed, or you lie on while sleeping.
• Within 3 inches of infusion or injection site.
• Near waistband or with irritations, scarring, tattoos, or lots of hair. If needed, trim site with electric clippers.

Use correct components: Dexcom G7 CGM System components aren’t compatible with any previous Dexcom products. Don’t mix with different generations.
Going through security check point: You can wear the Dexcom G7 CGM System sensor for the walk-through metal detector and Advanced Imaging Technology (AIT) body scanner. If you do, use your BG meter for treatment decisions until you leave the security area. This is because the Dexcom G7 CGM System hasn’t been tested with every x-ray and security scanner and you may not be able to bring a display device.
You can also ask for hand-wanding or full-body pat-down and visual inspection instead of going through any walk through body scanners or putting any part of the Dexcom G7 CGM System in the baggage scanning machine.

Interfering substance risks

• Hydroxyurea precaution
  Hydroxyurea is a medication used in the treatment of diseases including cancer and blood disorders; it is known to interfere with sensor readings. If you are taking hydroxyurea, your sensor readings will be higher than your actual glucose, which could result in missed hypoglycemia alerts or errors in diabetes management, such as giving yourself a higher dose of insulin due to falsely high sensor glucose values. The level of inaccuracy depends on the amount of hydroxyurea in your body. Don’t use your G7 System for diabetes treatment decisions if you are taking hydroxyurea. Talk to your physician about alternative glucose monitoring approaches.

• Acetaminophen precaution
  In previous generations of Dexcom CGM systems (G4/G5), acetaminophen couldaffect your sensor readings, making them look higher than they really were. However, with the Dexcom G7 CGM System, you can take a standard or maximum acetaminophen dose of 1 gram (1,000 mg) every 6 hours and still use the sensor readings to make treatment decisions. Taking higher than the maximum dose of acetaminophen (e.g. > 1 gram every 6 hours in adults) may affect the sensor readings and make them look higher than they really are.

Keep your sensor close to display device: Keep your sensor and display device within 20 feet with no obstacles between them. Otherwise, they might not be able to communicate.
Get alerts on display device you use: To get your alerts, set them on the display device you use. Your receiver won’t get the alerts you set in your app. Likewise, your app  won’t get the alerts you set on your receiver.
Display device is on: Make sure your display device is turned on or you won’t receive sensor readings or alerts.
Test speaker and vibrations: Test your receiver speaker and vibrations regularly. To make sure the speaker and vibrations work, plug in the receiver to charge. The Speaker Test screen appears for a few seconds. Follow the directions on the screen to test the speaker and vibrations. If it doesn’t beep and vibrate, contact technical support (in the app, go to Profile > Contact) and use your app or BG meter until the receiver is fixed.
Keep receiver clean and dry: Don’t submerge your receiver in water and don’t get dirt or water in the USB port. That could damage it.
