Home Screen, Rate of Change Arrows, and Errors
9.1 Introduction to Home Screens
In the previous chapter, you learned about calibrations: why they are
important and how to do them. Within five minutes of your final startup
calibration your sensor glucose readings begin!
In this chapter, you’ll learn three things. First, reading the home screen,
second, identifying your sensor glucose readings and trends: What do they
mean? What’s the best way to use trend information? And third, what you do if
you aren’t getting your sensor glucose readings.
The purpose of this chapter isn’t to tell you how to react to your trends but to
help you recognize where your glucose was and where it’s going. Your
healthcare professional can help you with your questions on what actions to
take based on your glucose trends.
After this chapter, you’ll be able to:
• Recognize home screen icons
• Locate sensor glucose reading
• Explain sensor glucose target range
• Recognize the importance of gray, yellow, and red colors
• Identify Low/High Glucose Alert levels on your trend graph
• Describe when you receive a High or Low sensor glucose reading
• Change trend graph views
• Cite differences between rate of change arrows
• Recognize error messages
