Sensor Glucose Readings and Trend Arrows
In Chapter 8 you learned how to read your home screen. When making a treatment decision,
you want to make sure you have a sensor glucose reading number and a trend arrow. Before
treating, look at your trend graph; it gives you your most recent reading.
When your home screen shows Signal Loss, High, or Low instead of a number, use your BG
meter.
Sometimes your home screen may show just a number, without a trend arrow. Once again, if
you don't have both a number and an arrow, you don't have enough information to treat. Use
your BG meter, not your Dexcom G5 for a treatment decision.
When you do have both a number and an arrow, you can use the number by itself to make
treatment decisions, just like you use your BG meter's number. To fine-tune your treatment
decisions, use both the number and the trend arrow. Trend arrows are your guides to the
amount of insulin to use. As an example, typically with a down arrow, you use less insulin,
and with an up arrow, more. Always check with you HCP when creating a treatment decision
plan.
Using Your Trend Arrows
In Chapter 8, you learned how arrows help you see the speed and direction of your sensor
glucose readings. Trend arrows and your sensor glucose reading help you determine your
best plan of action.
Remember—be patient; it takes time for your insulin to work. Don't "stack insulin" by giving
yourself too much insulin, too often, in too short a period of time. Before dosing, watch and
wait!
The table below gives you a general overview of how you use your Dexcom G5 trend arrows
to fine-tune your treatment decisions. Your HCP can help you determine what is your
appropriate low or high glucose value, and the best plan of action based on the direction of
the trend arrow.
