Risks and Benefits
When using any medical device, there are risks and benefits. In this chapter, you’ll learn what
they are, helping you decide if Dexcom G5 is right for you.
First, let’s review some possible risks.
3.1 Risks
There are some risks with using real-time CGM.
Not Receiving Alarm/Alerts
If you aren’t getting your CGM Alarm/Alerts, you run the risk of not knowing you are having a
severe low or high glucose event.
Some hardware issues preventing Alarm/Alerts:
• Alert function is turned off
• Transmitter and display device are out of range
• Receiver or smart device isn’t showing sensor glucose readings. For example, when
there are data gaps due to being out of range or “???”
• Receiver or smart device battery is dead
• Unable to hear Alarm/Alerts or feel vibration
• App not running in the background
• Signal Loss Alert won’t be heard if smart device is in Do Not Disturb mode
See recommended settings in Chapter 19, Troubleshooting, for more information.
