Are you looking for ways to ensure your Dexcom G7 sensor stays securely in place for the full 10-days? Keeping your sensor in place is crucial for accurate readings and peace of mind. In this blog post, we will walk you through the essential steps and tips to prevent your Dexcom G7 from falling off prematurely. From site preparation to overpatches, we will cover everything you need to know.

How do I keep my Dexcom G7 from falling off?

Follow these insertion guidelines to ensure your sensor stays secure in place for the entire duration.

Site Preparation

Ensure that your sensor site is flat, clean and thoroughly dry before inserting the sensor.
Apply an additional layer of adhesive to the skin before inserting the sensor, allowing it to dry first.
Make sure the patch remains flat on your skin and does not fold over.
Avoid placing the patch in areas with an abundance of hair.
Remove any old adhesive residue from previous sensors.

Patch Care

Seek assistance from a family member or friend when inserting your Dexcom G7 sensor.
Use a mirror to position the applicator or apply the overpatch accurately.
Keep the area dry and avoid excessive sweating during the first 12 hours after insertion.
If it becomes wet, pat the sensor dry as soon as possible.
Trim any peeling edges and apply medical tape if it starts to peel off your skin.

Where is the best place to put a Dexcom G7 sensor?

Dexcom G7 sensors can be inserted on the back of the upper arm, recommended for users aged 2 years and older, or on the upper buttocks, advised for ages 2-6 years old. Research indicates that wearing the sensor on the back of the upper arm yields the best sensor performance.

What is a Dexcom G7 Overpatch?

Some individuals may notice that their Dexcom G7 sensor patch begins to peel off before the end of their sensor session due to their skin type or level of activity. Applying an overpatch to your G7 sensor may assist in ensuring it remains securely attached for the full duration. Skin Grip G7 overpatches offer the following benefits:

Suitable for sensitive skin: they are irritation-free and hypoallergenic
Exceptional adhesion: resistant to sweat and water to maintain a strong adhesion even when wet.
Flexibility: made from a thin and flexible dynamic elastic material that will move with your body.
Easy application: features 4 tabs of paper backing for quick and hassle-free application.

How do I use my Dexcom G7 Overpatch?

Prepare the Skin: Make sure the area where you plan to apply the sensor and overpatch is clean and dry. Avoid using any lotions or creams on the skin prior to application.
Apply the Dexcom G7 Sensor: Insert the G7 sensor as instructed by the user manual.
Peel and Apply Skin Grip Overpatch: Align the overpatch with your sensor and carefully peel off the paper backing. You may find it easier to peel each tab off one at a time. Ensure that it covers the sensor and extends slightly beyond the edges.
Smooth and Secure: After applying the overpatch, press it firmly onto the skin to ensure it adheres proper. Smooth out any wrinkles or bubbles to ensure secure attachment.
Wait Before Activity: It’s recommended to wait at least one hour before engaging in any physical activities or exposing the sensor to moisture (such as swimming or taking a shower). This allows the sensor adhesive and overpatch to properly adhere to your skin.

Summary

Discover the benefits of overpatches, like Skin Grip’s Dexcom G7 adhesive patch. They are hypoallergenic, sweat, and water-resistant, and easy to apply. By using an overpatch and other measures discussed in this article, you can optimize the performance of your G7 sensor and enjoy reliable glucose readings throughout the full 10-day intended wear session.
