Like G6, the G7 sensors are less accurate on day 1 and usually improve within 24 hours.

G6 is factory calibrated. Unlike G6 sensors, the G7 sensors are pre-programmed with the factory calibration setting so that no user sensor code entry is required. However, users will still need to enter the 4-digit pairing code provided on the cap of each new Dexcom G7 applicator to pair a sensor to their compatible smart device or receiver. 

Users must end the Dexcom G7 sensor session or grace period before they start a new sensor. It can be ended one of two ways: 

• Automatically, when the grace period ends (they’ll receive an alert letting them know) 

• Manually, before the grace period ends 

The Dexcom G7 sensor sends glucose data to a user’s compatible display device for up to 10 days plus a 12-hour grace period at the end. After the grace period is over, users will need to replace their sensor to get glucose readings or alerts. No restarts are allowed. 

The Dexcom G7 sensor is indicated to be worn for up to 10 days, plus a 12-hour grace period at the end. 

Patients should speak with their healthcare provider about setting these three alerts, so they have more time to prevent their glucose from dropping too low: 

• Falling Fast: Patients can turn on this alert to let them know when their glucose is rapidly decreasing 

• Urgent Low Soon: The Urgent Low Soon alert can warn users in advance (within 20 minutes) of a severe hypoglycemic event (55 mg/dL), which helps give them time to take appropriate action before an event occurs. Patients must have this alert turned on 

• Low Alert: Patients should consider raising the level of their Low Alert settings to alert them before their levels go too low 

When a patient gets an alert, their top priority is to resolve it by making a treatment decision or fixing a system issue. Afterwards, they can acknowledge the alert on their display device by tapping OK. Until they acknowledge the alert, it will sound every 5 minutes. 

Dexcom G7 has new alert sounds and sound options. 

The new Quiet Mode allows users to override phone settings: 

• Quiet Mode (Vibrate): When this setting is enabled, all Dexcom G7 CGM System alerts will vibrate. Urgent Low Soon and technical alerts will still escalate to sound if not acknowledged. 

• Vibrate: All alerts vibrate but won’t sound. Users can set vibrate mode for up to 6 hours or indefinitely. Smartphone vibrate setting must be on for the alerts to vibrate. 

The Dexcom G7 Alert Profile replaces the Alert Schedule from Dexcom G6. The Alert Profile allows users to customize a second group of alerts, which can be used in two ways: 

• Switch between them manually 

• Set up a schedule to switch between alerts automatically; for example, to set different alert schedules for daytime and nighttime. 

The latest Apple iPhones and many of the popular Android smart phones are compatible with both Dexcom G6 and G7; however, there are some differences between the systems. Some of the newest Android phones are still being tested and will be added as they pass our testing.  Some of the older Android phones will not be added for Dexcom G7 as we prioritize adding new phones as quickly as possible.  

Dexcom G7 is compatible with the latest Apple iPhones and many popular Android devices. We are regularly adding more devices, so your patients can stay informed by visiting dexcom.com/compatibility.  

For patients whose smart device is not currently compatible with Dexcom G7, we encourage users to take advantage of the newly redesigned G7 receiver that is smaller, with a more vibrant, easier to read display.
