Chapter 1: Welcome

Congratulations! Your healthcare professional (HCP) thinks you are a great candidate to experience the Dexcom G6 Pro Continuous Glucose Monitoring System (G6 Pro) for a full sensor session. During this time, you can watch how what you do affects your glucose readings, see your glucose trends and much more.

1.1 Get Started

After Your Visit
During your office visit, your HCP inserted  the sensor, attached the transmitter andreviewed the Unblinded Patient Handout with you.
The handout guides you through setting  up the app, including entering your recommended High/Low alert levels and transmitter serial number (SN).
It also has information on making treatment decisions, who to call with questions, your return visit, etc.
For even more information, go to dexcom.com/guides to see the Dexcom G6 Pro System User Guide.

Chapter 2: Safety Statements

2.1 Indications for Use
The Dexcom G6 Pro Continuous Glucose Monitoring System (Dexcom G6 Pro System) is a real time continuous glucose monitoring device indicated for the management of diabetes in persons age 2 years and older in a home environment while under the supervision of a healthcare professional. The Dexcom G6 Pro System is intended to replace fingerstick blood glucose testing for diabetes treatment decisions. Interpretation of the real-time Dexcom G6 Pro System results should be based on the glucose trends and several sequential readings over time.
The Dexcom G6 Pro System may also be used as a retrospective glucose recording device indicated for assessing glycemic variability in persons age 2 years and older in a home environment while under the supervision of a healthcare professional. Retrospective interpretation of data recorded by the Dexcom G6 Pro System should be conducted solely by a healthcare professional.
The Dexcom G6 Pro System aids in detecting glucose excursions facilitating care plan adjustments. The Dexcom G6 Pro System is also intended to interface with digitally connected devices. The Dexcom G6 Pro System can be used alone or in conjunction with these digitally connected medical devices for managing diabetes or assessing glycemic variability.
2.2 Important User Information

Failure to use the G6 Pro and its components according to the instructions for use and all indications, contraindications, warnings, precautions, and cautions may result in missing a severe hypoglycemia (low blood glucose) or hyperglycemia (high blood glucose) occurrence and/or making a treatment decision that may result in injury.
If glucose alerts and readings from G6 Pro do not match symptoms or expectations, use a fingerstick blood glucose value from a blood glucose meter to make diabetes treatment decisions.
Seek medical attention when appropriate. Please review the product instructions before using the G6 Pro. Indications, contraindications, warnings, precautions, cautions, and other important user information can be found in the product instructions that are included with, or accompany, the G6 Pro. Discuss with your healthcare professional how you should use the information displayed on the G6 Pro to help manage your diabetes.
The product instructions contain important information on troubleshooting the G6 Pro and on the performance characteristics of the system.

2.3 Contraindications
No MRI/CT/Diathermy
Don’t wear your CGM (sensor, transmitter, or smart device) for magnetic resonance imaging (MRI), computed tomography (CT) scan, or high-frequency electrical heat (diathermy) treatment.
The G6 Pro hasn’t been tested in those situations. The magnetic fields and heat could damage the components of the G6 Pro, which may cause it to display inaccurate G6 Pro sensor glucose readings (G6 Pro readings) or may prevent alerts. Without G6 Pro readings or alarm/alert notifications, you might miss a severe low or high glucose event.

2.4 Warnings

Where to Insert: Belly or Buttocks?

All patients can use their bellies (abdomen). Patients 2 to 17 years old can also choose their upper buttocks. Look for a place on your belly or upper buttocks where you have
some padding.
The sensor is not tested or approved for other sites. Talk to your healthcare professional about the best site for you.
Inspect
Don’t use a damaged or cracked transmitter. A damaged transmitter could cause injuries from electrical shocks and may make the G6 Pro not work correctly.
Where to Store
Store sensors at room temperature or in a refrigerator – as long as it’s between 36°F and 86°F. Don’t store sensors in the freezer.

Read User Materials
Before using G6 Pro, carefully read the  materials included with it. If you don’t,you might:

• Not use the G6 Pro correctly
• Not understand G6 Pro information
• Affect how well it works

Do Not Ignore Low/High Symptoms
You shouldn’t ignore how you feel. If glucose alerts and G6 Pro readings don’t match what you’re feeling, use blood glucose meter (meter) to make diabetes treatment decisions or, if needed, seek immediate medical attention.
When in doubt, get meter out.

No Number, No Arrow, No CGM
Treatment Decision
If G6 Pro doesn’t show a number or arrow, or readings don’t match symptoms, use meter to make diabetes treatment decisions.
No number, no arrow, no treatment decision.
When in doubt, get meter out.
Don’t use G6 Pro if pregnant, on dialysis, or critically ill
It is not known how different conditions or medications common to theses populations may affect performance of the system. G6 Pro readings may be inaccurate in these populations.
Follow G6 Pro instructions. If not, you could have a severe low or high glucose event.
Check Settings
When using smart device, confirm that volume is turned up, phone is not muted, and headphones aren’t plugged in. If volume is not turned up, the device is muted, or headphones are plugged in, you won’t hear the sound of any notifications, including important alarms.
When headphones are connected to an Android ® , alarm/alerts will sound through the headphones and the speaker. On Apple ® , they will sound only in the headphones. Some notifications are silent during the first visual and vibrate notification and then make a sound on the second notification. If an alert isn’t cleared, it repeats at half volume after 5 minutes and at full volume after 10 minutes.
The smart device vibrations for alerts aren’t different than vibrations originating from sources other than the Dexcom CGM app. (Vibratory annunciation only available in smart devices with vibratory functionality.)
If the smart device is on mute, only these notifications make a sound:

Glucose Alarm:

• Urgent Low

System Alerts:

• Sensor Failed
• Transmitter Failed
• App Stopped

Android users must allow Do Not Disturb Permission to use the app.

Bluetooth®

The transmitter talks to the app with Bluetooth. Make sure the smart device Bluetooth is on. If not, you won’t get alarm/alerts or CGM information.

Notifications
Make sure smart device settings allow Dexcom app notifications to show on Lock screen. This will allow notifications to be seen without unlocking your phone.
Apple® : During G6 Pro setup, enable Dexcom app notifications or you won’t get alarm/alerts.
App Use: Smart device may close the Dexcom app automatically when other apps are being used, like a game, or if too many apps are open. If the Dexcom app is closed, you won’t get sensor glucose information. Occasionally verify Dexcom app is open.
Battery: The app must always be running in the background and may drain your smart device battery. Keep the battery charged.
Compatibility: Dexcom tests the app’s compatibility with smart device’s Operating System to ensure it works. Before upgrading smart device or its operating system, always check dexcom.com/compatibility.
Automatic updates of the app or device operating system can change settings or shut down the app.
Time
Let the date and time on smart device automatically update when traveling across time zones or switch between standard and daylight-saving times.
Don’t manually change smart device time. It can make the time on the trend screen wrong and the app may stop displaying data.
Follow G6 Pro instructions. If not, you could have a severe low or high glucose event.
Use as Directed
The transmitter is a small part and poses a choking hazard, particularly for children.
Use Meter During Sensor Warmup
When a new sensor is started, there won’t be any G6 Pro readings or alarm/alerts. Use meter to make treatment decisions during the 2-hour sensor warmup period.
Follow G6 Pro instructions. If not, you could have a severe low or high glucose event.
Wire Breaks Off
Don’t ignore broken or detached sensor wires. A sensor wire could remain under your skin. If this happens, please contact our 24/7 Technical Support.
If a sensor wire breaks off under skin and you can’t see it, don’t try to remove it. Contact your Healthcare professional. Also seek professional medical help if you have symptoms of infection or inflammation – redness, swelling, or pain – at the insertion site.

2.5 Precautions
Don’t Start Past “Use By Date”
Don’t start using a sensor past its Use By Date because it may give incorrect results. The Use By Date is in YYYY-MM-DD (Year-Month-Day) format on the sensor package label beside the hourglass symbol.
Check Package
Don’t use sensor if its sterile package has been damaged or opened, because it might cause an infection.
Clean and Dry Skin
Clean and dry your hands, then put on your gloves before inserting your sensor. Clean insertion site with alcohol wipes to prevent infections. Don’t insert the sensor until skin is dry. If insertion site is not clean and completely dry, there’s a risk of infection or the transmitter holder not sticking well. Make sure you don’t have insect repellent, sunscreen, perfume, or lotion on your skin.
Where to Insert: Things to Check
Don’t open packages until ready to use.
Keep the safety guard on until you put the G6 Pro applicator against the patient’s skin. If you remove the safety guard first, you may hurt the patient by accidentally pushing the button that inserts the sensor before you mean to.
Change the insertion site with each sensor. Using the same site too often might not allow the skin to heal, causing scarring or skin irritation.

Sensor placement is important.
Choose a site:

• At least 3 inches from insulin pump infusion set or injection site
• Away from waistband, scarring, tattoos, irritation, and bones
• Unlikely to be bumped, pushed, or laid on while sleeping

Follow G6 Pro instructions. If not, patient could have a severe low or high glucose event.

Use Correct Transmitter, and Sensor
G6 Pro components are not compatible with any previous G6 products. Do not mix transmitters and sensors from different generations.

Avoid Sunscreen and
Insect Repellent
Some skin care products, such as sunscreens and insect repellents, can make the plastic used in G6 Pro crack. Before using G6 Pro, make sure there are no cracks in transmitter, and transmitter holder. If you find a crack, please contact Technical Support.
Do not allow insect repellent, sunscreen, perfume or lotion to contact the G6 Pro. After using skin care products, wash hands  before touching G6 Pro. If any skin care products get on G6 pro, immediately wipe with a clean cloth.

Going Through Security Check Points

When wearing G6 Pro, ask for hand-wanding or full-body pat-down and visual inspection instead of going through the Advanced Imaging Technology (AIT) body scanner (also called a millimeter wave scanner) or putting any part of the G6 Pro in the baggage x-ray machine.
You can wear the G6 Pro for the walkthrough metal detector.
Not sure what kind of machine it is? Be safe
– either ask the TSA officer, request handwanding, or request full-body pat- down.
Interfering Substance Risks

Acetaminophen
In previous generations of Dexcom CGM systems (G4/G5), acetaminophen could affect sensor readings, making them look higher than they really were. However, with the G6 Pro, you can take a standard or maximum acetaminophen dose of 1 gram (1,000 mg) every 6 hours and still use the G6 Pro 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 G6 Pro readings and make them look higher than they really are. Hydroxyurea
Hydroxyurea is a medication used in the treatment of diseases including cancer and sickle cell anemia; it is known to interfere with readings from your sensor. If you are taking hydroxyurea, your sensor glucose 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. Do not use your Dexcom CGM System for diabetes treatment decisions if you are taking hydroxyurea.
Follow G6 Pro instructions. If not, you could have a severe low or high glucose event.

Treatment Decisions
Use your G6 Pro reading and trend arrow to make treatment decisions.
Know Your System
Don’t rely on the G6 Pro app until you understand how to use it and your device’s Bluetooth.

Keep Transmitter Close to Display Device
Keep transmitter and display device within 20 feet with no obstacles (like walls or metal) between them. Otherwise, they might not be able to communicate. If water is between the transmitter and the display device – for example, while you’re showering or swimming – keep them closer to each other. The range is reduced because Bluetooth doesn’t work as well through water.
Does your smart device work?
If the smart device is turned off (shut down), it will not show G6 Pro readings or alarm/ alerts. Make sure the display device is turned on, the battery is charged, the screen is not broken and the speaker works.
Follow G6 Pro instructions. If not, you could have a severe low or high glucose event.
Check Peripheral Devices
Use headphones with a smart device? What about Bluetooth speakers or a smart watch? When using peripherals, you may get alarm/ alerts on only one device or peripheral, not all. After connecting any peripheral devices, make sure that smart device settings still allow for receiving alarms or alerts.
2.6 Caution
US Federal law restricts the sale of G6 Pro to be made by or on the order of a physician.

Chapter 3: Risks and Benefits

3.1 Risks
The risks with using G6 Pro are:

• Sensor insertion issues

• Local skin irritation from adhesive patch
  Additional risks if using the G6 Pro app are:

• Not getting your alarm/alerts

• Using G6 Pro to make treatment decisions when you shouldn’t
  This section covers each of those risks in detail.
  Follow system instructions. If not, you could have a severe low or high glucose event.

Sensor Insertion Risks
It’s uncommon, but inserting the sensor can cause infection, bleeding, or pain. Only a few patients in the clinical studies got slight redness and swelling.
There is a remote chance a sensor wire could break or detach and remain under the skin. Sterile broken or detached sensor wires usually don’t pose a significant medical risk.
If a sensor wire breaks off or detaches and remains under your skin, you should contact a Healthcare Professional and
Technical Support (24/7):

Toll call: 1.858.200.0200

Not Getting Alarm/Alerts
If you’re using the G6 Pro system in real-time and you aren’t getting your alarm/ alerts, you could have severe low or high glucose without knowing it.
Check smart device:

• Battery charged: If the smart device battery is dead, you won’t get readings or alarm/alerts.

• App on: Keep the app on to get readings or alarm/alerts.

• Alerts on: Leave the alert function on to get alarm/alerts.

• Volume up: Keep the volume loud enough to hear alarm/alerts.

• Speaker and vibrations work: If the speaker or vibrations aren’t working, you won’t hear or feel alarm/alerts.

• In range: Keep smart device no more than 20 feet from transmitter, with no obstacles between them. They have to be that close to communicate. If they aren’t in range,
  you won’t get readings or alarm/ alerts.

• No system errors: If you get a system error – such as No Readings, Sensor Error, or Signal Loss – you won’t get readings or alarm/alerts.

• During warmup and after session ends: You won’t get alarm/alerts or readings during the 2-hour warmup or after a G6 Pro session ends.

Using G6 Pro for
Treatment Decisions
You can use your G6 Pro to treat for a low or dose for a high in all but these few situations. See table below:

treatment decision
How you feel is inconsistent with your CGM

G6 Pro reading

| Take a fingerstick with your blood glucose meter to make a treatment decision
Your CGM displays a sensor glucose number and arrow(s)| Use your CGM to make a treatment decision
Your CGM display is missing G6 Pro reading (number) or arrow(s), or both| Take a fingerstick with your meter to make a treatment decision

3.2 Benefits
Some benefits of using G6 Pro are:

• Knowing trends
• Making treatment decisions using your G6 Pro
• Managing your diabetes without the need for routine fingersticks
• Getting alerted for low and high readings
• Determining how often your glucose is high, low, or in range

This section covers each of those benefits in detail.

Knowing Your Trends
The G6 Pro sends a reading every 5 minutes. It also provides reports and views of your information so you can detect and reflect on trends, patterns, and how your body responds to different things, like exercise, stress, or food you have eaten. This provides you with a more complete picture of your glucose and lets you see how your daily habits impact your glucose control.
Making Treatment Decisions Using G6 Pro

You can use your G6 Pro reading and trend arrow to make treatment decisions – like  treating for a low or dosing for a high. See‘Can I make treatment decisions with G6 Pro,’ ‘No Number, No Arrow, No CGM Treatment Decision’ and ‘Using G6 Pro for Treatment Decisions’ for more information. With G6 Pro there is no need to take fingersticks to calibrate the system or for treatment decisions (as long as your symptoms match your readings). This can reduce the pain and burden of excessive fingersticks (Aleppo 2017) and reduce potential errors due to inaccurate calibration.
Helping Your Diabetes Management
The alarm/alerts feature keep you aware of your glucose levels. Alarm/alerts notify you when your glucose goes high or goes too low. This lets you take action to prevent glucose from going too low or high (Pettus 2015).
Some people perceive an increase in their quality of life and peace of mind when using  real-time CGM (Polonsky 2017). The glucoseinformation will provide an insight to the state of your glucose control and the patterns you and your clinician observe may help inform better treatment decisions.

Chapter 6: Treatment Decisions

With Dexcom G6 CGM (G6), you can  make treatment decisions without using your blood glucose (BG) meter (meter).
But sometimes you must use your meter instead of the G6 Pro. And other times it’s best not to treat, just watch and wait.
Work with your healthcare professional to review what works best for you when making treatment decisions.
6.1 How to Use the Trend Arrows
The trend arrows help you decide how much to dose.

| Up arrow: Take a little more insulin
Down arrow: Take a little less insulin

Chapter 7: Ending Your Sensor Session

Each sensor session lasts 10 days.
Your G6 Pro alerts you when you have 24 hours left in your session, then 6 hours, then 2 hours, and finally, 30 minutes. You can end your session anytime during this period or wait for your final alert letting you know your session has ended.
Remember, after your sensor session has ended, you won’t get any G6 Pro readings. Make sure you return the transmitter within 30 days of sensor insertion.

7.1 Remove Your Sensor
Take sensor off your body.

TSA requests you tell the Security Officer you’re wearing a continuous glucose monitor and want to be hand-wanded or get a fullbody pat-down with a visual inspection of your sensor and transmitter. Let the Security Officer know you can’t remove the sensor because it’s inserted under your skin.

Security Equipment to Use
Hand-wanding, pat-down, visual inspection, and walk-through metal detector: If you’re wearing or carrying your G6, use any of these screening methods.
Security Equipment to Avoid
Body scanners: Don’t go through an advanced imaging technology  body scanner, like a millimeter wave scanner, when wearing your G6.
X-Ray machines: Don’t put your G6 components through x-ray machines.

In a Plane
To use your smart device to get sensor glucose information while in the plane, after  switching to airplane mode, then turn Bluetooth on.
