Dexcom ONE safety
statements
Indications for use
The Dexcom ONE Continuous Glucose Monitoring System (Dexcom ONE) is a glucose
monitoring system indicated for persons, including pregnant women, ages 2
years and older. Dexcom ONE is designed to replace fingerstick blood glucose
(BG) testing for diabetes treatment decisions.
Interpretation of Dexcom ONE results should be based on the glucose trends and
several sequential readings over time. Dexcom ONE also aids in the detection
of episodes of hyperglycemia and hypoglycemia, facilitating both acute and
long-term therapy adjustments.
Dexcom ONE is intended for use by patients at home and in healthcare
facilities.
Important user information
Please review the product instructions before using Dexcom ONE. Indications,
contraindications, warnings, precautions, and other important user information
can be found in the product instructions that are included with Dexcom ONE.
You and your healthcare professional must discuss how you should use the
information displayed on Dexcom ONE to help manage your diabetes. Getting
familiar with the system could take days, weeks, or even months. The product
instructions contain important information on troubleshooting Dexcom ONE and
on the performance characteristics of the system.
Contraindication
· No MRI/CT/diathermy MR unsafe MR
Do not wear any component of Dexcom ONE during magnetic resonance imaging
(MRI), computed tomography (CT) scan, or highfrequency electrical heat
(diathermy) treatment.
Dexcom ONE User Guide
5
Dexcom ONE safety statements
Dexcom ONE has not been tested in those situations. The magnetic fields and
heat could damage the components of Dexcom ONE, which may cause it to display
inaccurate CGM sensor glucose readings (Dexcom ONE readings) or may prevent
alerts. Without Dexcom ONE readings or alert notifications, you might miss a
severe low or high glucose event.
Warnings
· Read user materials
Before you use your Dexcom ONE, carefully read the materials included with it.
If you do not, you might:
· Not use Dexcom ONE correctly
· Not understand Dexcom ONE information
· Affect how well it works
· Do not ignore low/high symptoms
Do not ignore how you feel. If your glucose alerts and Dexcom ONE readings do
not match what you are feeling, use your blood glucose meter (BG meter) to
make diabetes treatment decisions or, if needed, seek immediate medical
attention.
When in doubt, get your BG meter out.
· No number, no arrow, no CGM treatment decision
If your Dexcom ONE does not show a number or arrow, or your Dexcom ONE
readings do not match your symptoms, use your BG meter to make diabetes
treatment decisions.
No number, no arrow, no treatment decision. When in doubt, get your BG meter
out.
· Do not use if…
Do not use Dexcom ONE if you are on dialysis, or critically ill. It is not
known how different conditions or medications common to these populations may
affect performance of the system. Dexcom ONE readings may be inaccurate in
these populations.

Dexcom ONE User Guide
Dexcom ONE safety statements
· Take Healthcare Professional Advice
Has your healthcare professional given you selfmonitoring tasks? You should
keep doing them. Having Followers does not replace medical advice.
Follow Dexcom ONE instructions. If you do not, you could have a severe low or
high glucose event.
Precaution
· Avoid sunscreen and insect repellent
Some skin care products, such as sunscreens and insect repellents, can make
the plastic used in your Dexcom ONE crack. Before using your Dexcom ONE, make
sure there are no cracks in your transmitter and transmitter holder. If you
find a crack, please contact Technical Support at dexcom.com, or contact your
local Dexcom representative. Do not allow these skin care products to contact
your Dexcom ONE. After using skin care products, wash your hands before
touching your Dexcom ONE. If any skin care products get on your Dexcom ONE,
immediately wipe with a clean cloth.
· Hydroxyurea precaution
If you are taking hydroxyurea, your Dexcom ONE readings may be falsely
elevated and result in missed hypoglycemia alerts or errors in diabetes
management decisions. The level of inaccuracy depends on the amount of
hydroxyurea in your body. Use your BG meter.
· Going through security check point
When wearing your Dexcom ONE, 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 Dexcom ONE system in the baggage x-ray machine.
You can wear Dexcom ONE for the walk-through metal detector. If you do, use
your BG meter for treatment decisions until you leave the security area.
Because we have not tested every x-ray and scanner, we do not know if they
damage Dexcom ONE.
Dexcom ONE User Guide

Dexcom ONE safety statements
Not sure what kind of machine it is? Be safe request either hand-wanding or
full-body patdown.
Start up safety statements
Warnings
· Use BG meter during startup
When you start a new sensor, you will not get any Dexcom ONE readings or
alerts until you enter your sensor code. Use your BG meter to make treatment
decisions during the 2-hour sensor warmup period.
Precautions
· Use correct sensor code
When you start a new sensor, you must enter a code into your display device to
use Dexcom ONE. Each sensor has its own code printed on the back of the
adhesive patch. Do not use a code from a different sensor or make up a code.
If you do not enter the correct code, your sensor will not work as well and
could be inaccurate.
System/hardware/software safety statements
Warnings
· Sensor wire breaks off or detaches
Do not ignore broken or detached sensor wires. A sensor wire could remain
under your skin. If this happens, please contact Technical Support at
dexcom.com, or contact your local Dexcom representative.
If a sensor wire breaks off under your skin and you cannot see it, do not try
to remove it. Contact your Healthcare Professional as soon as possible. Also
seek professional medical help if you have symptoms of infection or
inflammation redness, swelling, or pain at the insertion site.

Dexcom ONE safety statements
Precautions
· Keep transmitter close to display device:
Keep your transmitter and display device within 6 meters with no obstacles
(like walls or metal) between them. Otherwise, they might not be able to
communicate. If water is between your transmitter and the display device for
example, if you are showering or swimming keep them closer to each other.
The range is reduced because Bluetooth does not work as well through water.
· Keep receiver clean and dry (receiver is an optional display device): Do not
submerge your receiver in water and do not get dirt or water in the USB port.
That could damage it.
· Get alerts on display device you use
You will be prompted to turn on the optional alerts when setting up your
Dexcom ONE system. You must turn them on to get glucose and system alerts.
No glucose alerts unless you turn them on. Turn alerts on during setup to get
glucose and system alerts when sensor warmup is over. Dexcom ONE alerts will
NOT override your phone’s settings. You will NOT hear high or low glucose
alerts if your phone is set to silent (sound is off). Check your phone’s
settings, or you may miss an alert.
· Is it on?
If the display device is turned off (shut down), it will not show Dexcom ONE
readings or alerts. Make sure your display device is turned on.
· Check smartphone accessory devices
When using smartphone accessory devices (such as headphones or Bluetooth

Use alerts to achieve goals
You should talk with your healthcare professional to customize your alerts to
help you achieve your goals. For example, are you worried about insulin
stacking–taking doses too close together?
To use your Dexcom ONE as a tool to avoid insulin stacking, your healthcare
professional should advise you to turn on the Snooze feature in your High
Alert setting. That way, you can choose how long you want to wait before
getting another High Alert after you confirm the first one. The alert will
repeat at the interval you choose until your Dexcom ONE readings are back in
your target range. This reminds you to check your readings later to make sure
your glucose values have come down.
Dexcom ONE User Guide
27
Alerts
The screens below show Snooze Alerts set at 2 hours. If your Dexcom ONE readings remain high for 2 hours after your first High Alert, you will get another alert. This lets you know you might want to take more insulin. If 2 hours pass and you are in your target range, your High Alert will not repeat.

Treatment decisions
With Dexcom ONE, you can make treatment decisions without using your blood
glucose (BG) meter (BG meter). However, you should keep using your BG meter to
make treatment decisions until you know how Dexcom ONE works for you.
Sometimes you must use your BG meter instead of Dexcom ONE. And other times it
is best not to treat, just watch and wait.
Work with your healthcare professional to put together a plan for making
treatment decisions. Always use your healthcare professional’s instructions to
treat.
You can keep using your BG meter until you are familiar with your CGM.
Both your BG meter and your CGM give you a number. They measure glucose from
different sources (blood and interstitial fluid), so those numbers may be
different. And, if you took a lab test at the same time, the lab result may
give you a third number. The lab result is considered the most accurate
number.
5.1 When to use your BG meter instead of your Dexcom ONE
We do not recommend continuous glucose monitoring for people who cannot or
will not:
· Use their BG meter to test their blood glucose if their symptoms do not
match their Dexcom ONE readings.
· Keep in touch with their healthcare professional about diabetes management.
Dexcom ONE User Guide

· Your Dexcom ONE readings do not match your symptoms.
Example: you do not feel right but your readings show your glucose is in
target 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.
5.2 When to watch and wait
There are times when you should not treat at all, just watch and wait.
Stacking insulin: Do not stack insulin by taking doses too close together.
Wait at least 2 hours between doses so you do not accidentally force your
glucose down too low. Sometimes, it is best to watch and wait.

5.3 How to use the trend arrows
Talk to your healthcare provider about using the trend arrows to determine how
much insulin to take.

is falling

Using Dexcom ONE for treatment decisions
You can use your Dexcom ONE for treatment decisions in all but a few
situations.
Situation: How you feel is inconsistent with your Dexcom ONE reading
Treatment Decision Tool: Take a fingerstick for a BG measurement and use the
number to make a treatment decision
Situation: Your CGM display is missing Dexcom ONE reading (number) or
arrow(s), or both
Treatment Decision Tool: Take a fingerstick for a BG measurement and use the
number to make a treatment decision
Some users found accuracy between different sensors varied significantly. When
you insert each sensor, pay attention to its accuracy before deciding to use
it for treatment decisions.
For more information on how to make treatment decisions using your Dexcom ONE,
go to Chapter 5.
Paracetamol/acetaminophen interfering substance risks
With the Dexcom ONE, you can take a standard or maximum
paracetamol/acetaminophen dose of 1 gram (1,000mg) every 6 hours and still use
the Dexcom ONE readings to make treatment decisions. Taking higher than the
maximum dose of paracetamol/acetaminophen (e.g. > 1 gram every 6 hours in
adults) may affect the Dexcom ONE readings and make them look higher than they

Hydroxyurea interfering substance risks
Hydroxyurea, a medication used to treat some cancers or blood disorders, may
falsely elevate your Dexcom ONE readings and result in missed hypoglycemia
alerts or errors in diabetes management decisions. The level of inaccuracy
depends on the amount of hydroxyurea in your body. Use your BG meter.

Risks and benefits
Sensor insertion risks
Inserting the sensor can cause infection, bleeding, or pain. Some people are
sensitive to the sensor adhesive. If you have significant skin irritation,
such as itching, burning, and/or rashes at the site of the adhesive patch,
contact your healthcare professional.
No sensor wires broke or detached in clinical studies; however, there is a
remote chance a sensor wire could break or detach and remain under your skin.
Sterile broken or detached sensor wires usually do not pose a significant
medical risk. If a sensor wire breaks off or detaches, remains under your
skin, and shows signs of infection or inflammation, contact your Healthcare
Professional and Technical Support at dexcom.com, or contact your local Dexcom
representative.
E.2 Benefits
Some benefits of using your Dexcom ONE are:
· Managing your diabetes
· Knowing where your glucose was and where it is going
· Getting immediate feedback on your lifestyle decisions
· Making treatment decisions using your Dexcom ONE
· Decreasing the pain and hassle from frequent blood glucose testing, sparing
the fingertips
Knowing your trends
The Dexcom ONE not only sends you a glucose reading every 5 minutes but also
provides overviews of your glucose trends and patterns. This lets you see the
overall picture and how the foods you eat, medications you take, and exercise
impact your glucose levels.

Risks and benefits
Making treatment decisions using Dexcom ONE
You can use your Dexcom ONE reading and trend arrow to make treatment
decisions. Go to Chapter 5 for more information. No fingersticks calibration
is needed. This reduces the pain and burden of excessive fingersticks (Price
and Walker, 2016) and potential errors due to inaccurate calibration (Wadwa,
2018).
Helping your diabetes management
The optional alerts features notify you when your glucose goes outside your
target range. This lets you take action to prevent glucose from going too low
or too high. Go to Chapter 4 for more information.

transmitted from the transmitter to the display device. The Dexcom ONE CGM
System is designed to only accept radio frequency (RF) communications from
recognized and paired display devices.
Security measures
The Dexcom ONE System is designed to transmit data between the transmitter and
designated display devices in accordance to the industry standard BLE
protocols. It will not accept radio frequency (RF) communications using any
other protocol, including Bluetooth classic communication protocols.
In addition to the security provided by the BLE connection, communication
between the Dexcom ONE transmitter and the Dexcom ONE receiver and mobile
application is protected by additional levels of security and safety
mitigations using an encrypted and proprietary data format. This format embeds
various methods to verify data integrity and to detect potential instances of
data tampering. While the format is proprietary, industry standard encryption
protocols (e.g., RSA and AES) are used in different parts of this proprietary
data format.
Unless disabled, the Dexcom ONE mobile application regularly communicates with
Dexcom Servers. Communication between the Dexcom ONE applications and Dexcom
Servers is protected by a number of mechanisms, designed to safeguard against
data corruption. This includes industry standard JWIT token based
authentication and authorization. All such communication takes place
exclusively over an encrypted data path using industry standard SSL format.

Electromagnetic interference can still occur in the home health care
environment as control over the EMC environment cannot be guaranteed. An
interference event can be recognized by gaps in sensor readings or gross
inaccuracies. The user is encouraged to try to mitigate these effects by one
of the following measures:
· If the Dexcom ONE sensor reading does not match your symptoms or
expectations take a fingerstick. Usually, the Dexcom ONE sensor reading is
close to the BG meter value. Your Dexcom ONE is working normally if those two
numbers are:
· Within 20% (if Dexcom ONE reading is 3.9 or more)
or
· Within 1.1 mmol/L (if Dexcom ONE reading is less than 3.9)
Dexcom ONE User Guide
73
Technical information
For example, your Dexcom ONE is working normally in this situation:
· Dexcom ONE reading: 6.5
· Acceptable range (20%): 5.2 7.7 mmol/L
· BG meter value: 5.5
· Your Dexcom ONE may not be working normally when those two numbers are:
· More than 30% apart (if Dexcom ONE reading is 3.9 or more)
or
· More than 1.7 mmol/L apart (if the Dexcom ONE reading is less than 3.9)
In that case, use your BG meter value to make treatment decisions.
For example, your Dexcom ONE may not be working normally in this situation:
· Dexcom ONE reading: 6.5
· Acceptable range (30%): 4.6 8.4 mmol/L
· BG meter value: 9
Your Dexcom ONE may be working normally but is not aligned with your BG meter
when those two number are:
· Between 21% and 30% apart (if Dexcom ONE reading is 3.9 or more)
or
· Between 1.2 mmol/L and 1.7 mmol/L apart (if Dexcom ONE reading is less than
3.9)
In that case, make treatment decisions on the number that matches your
symptoms and expectations.
· If display device misses 20 minutes of sensor glucose data (4 readings), the
Signal Loss error displays. To resolve, go to Appendix A: Troubleshooting.
· If display device shows the loading screen unexpectedly and does not display
the trend screen within 3 minutes, contact Technical Support at dexcom.com, or
contact your local Dexcom representative. For more information, go to Appendix

· Prepare Dexcom ONE for your patient
· Tell the patient what Dexcom ONE is and how it works
· Set up the system with the patient
· Follow up with the patient to share insights on their glucose trends,
patterns, and statistics
This helps both of you manage their diabetes better. The following sections go
through each step and give you resources to share with your patients as you
guide them through a sensor session.
H.2 Prepare Dexcom ONE for patient
Decide whether the patient should be able to see their Dexcom ONE readings
(unblinded). Will this motivate them to manage their diabetes better?
Whether the receiver is blinded or unblinded, all Dexcom ONE patients:
· Must carry their receiver to record data for later analysis
· Will get system alerts, such as Signal Loss and Brief Sensor Issue
The differences between blinded and unblinded are:
· Unblinded: Receiver shows patient’s sensor reading, trend arrow, graph, Low
and High glucose alerts.
· Blinded: Receiver does not show any unblinded information. In addition, it
does not show the Warmup Complete message.
