254Using the Dexcom G5 Mobile System for Treatment Decisions
13.2 Safety Statement
WARNING
Do:
Do take a BG measurement with your BG meter and use the BG value for treatment
decisions (such as how much insulin to take) if your Dexcom G5 Mobile does not display
both a number and a trend arrow.
Why: Not having both a number and the arrow means you may be getting inconsistent or
inaccurate sensor glucose readings.
Consequences: Using inconsistent or inaccurate sensor glucose readings for treatment
decisions could result in you missing a severe low or high blood glucose event or making a
treatment decision that results in injury.
13.3 Treatment Decisions: The Basics
How Do You Know You’re Ready?
Whether you’re new to Dexcom or experienced, you should keep using your BG meter
to make treatment decisions until you know how Dexcom works for you. Don’t rush!
It may take days, weeks or months for you to gain confidence in using your CGM to make
treatment decisions. Confirm your glucose readings using your BG meter so you
understand that:
• The accuracy you experience with each newly inserted sensor may vary
• A sensor might work differently in different situations (meals, exercise, first day of use,
etc.)
Before you start making treatment decisions with your Dexcom G5 Mobile, work with
your HCP and learn the basics: When do you need to use a BG meter instead of relying on
your Dexcom G5 Mobile? How can you avoid insulin stacking? Once you and your HCP are
comfortable that you know the basics, you’re ready!
Some users have reported that performance may vary significantly between sensors; pay
attention to how each newly inserted sensor is working for you when deciding whether to
make treatment decisions based on your glucose readings. If your symptoms don’t match
your glucose readings, use your BG meter when making treatment decisions. If your glucose
readings don’t consistently match your symptoms or BG meter values then talk to your HCP
