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 entering your two initial calibrations 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 HCP 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 status icon and error messages
