Quick Tip: For active days, waterproof or moisture-resistant patches can keep your sensor secure. Follow these steps to avoid detachment, maintain accurate readings, and prevent irritation.
Getting the skin ready is key to making sure the sensor stays in place longer. A well-prepped surface helps reduce the chances of early detachment.
For kids aged 2-6, the upper buttocks is a recommended spot [5]. Avoid these areas:
After choosing the right spot, it's time to prepare the skin properly.
Start by applying a skin barrier (like Cavilon or Skin Prep). Then, use an adhesive enhancer (such as Skin Tac or Mastisol) in a circular pattern around the site. Allow each layer to dry for 30-60 seconds before moving on [1][2][5].
Choosing the right spot is just the beginning - how you apply the sensor is just as important.
Once your skin is prepped, it's time to focus on placing the sensor accurately:
The back of the upper arm is the go-to spot. Make sure the sensor is positioned horizontally for the best results [3].
If you're applying it to your abdomen, sit down to help smooth the skin and avoid any wrinkles in the adhesive [1].
Getting the sensor to stick well requires applying the right amount of pressure:
Temperature plays a big role in how well the adhesive works. Follow these tips for the best results:
Once applied, wait 10-15 minutes before engaging in activities or getting the sensor wet. This helps the adhesive set properly [5].
Once your sensor is in place, you can improve its adhesion with overpatches. Here’s a quick comparison of popular options:
| Feature | Dexcom Standard | Pump Peelz | Skin Grip |
|---|---|---|---|
| Material | Medical acrylic | Hypoallergenic vinyl | Breathable fabric |
| Design Options | Solid color | 200+ custom patterns | Skin-tone colors |
| Wear Time | 10 days | 10-14 days | 10 days |
If you’re active and want something stylish, Pump Peelz stands out with over 200 patterns [3].
The ideal time to apply an overpatch is right after inserting the sensor but before the warm-up period begins [1]. This helps prevent the edges from peeling early [1].
Follow these steps for proper application:
The G7 overpatch is designed to cover an extra 1/2 inch around the sensor [7].
For extra staying power:
These tips can help your sensor stay put, even during active days.
Taking care of your sensor daily helps it last longer and work properly.
Moisture can weaken the adhesive holding your sensor in place. To protect it:
For sweat-related challenges, here are some practical solutions:
| Activity | Suggested Fix |
|---|---|
| Swimming/Bathing | Use a waterproof overlay patch |
| High-Intensity Exercise | Apply a moisture-wicking patch |
| Outdoor Activities | Opt for a moisture-resistant overlay |
Despite careful application, the edges of your sensor may lift during daily wear. Acting quickly when this happens helps maintain its accuracy.
Skin irritation can happen due to moisture buildup or sensitivity to the adhesive. To minimize this:
To get the most out of your Dexcom G7's 10-day wear, focus on preparation, proper application, and regular care. Start with thorough skin preparation to ensure strong adhesion from the beginning[6].
Placement matters too. Applying the sensor with even pressure helps secure the adhesive to your skin[3]. For extra support, especially during physical activity, use the included overpatch to keep the sensor in place.
Daily care is key to extending the sensor's lifespan. By consistently following these steps and staying mindful of your surroundings, you can maintain reliable sensor performance and accurate glucose readings throughout the recommended wear period.
To get the best stick, pair these adhesives with the application methods mentioned in the Overpatch section.
For the best outcome:
Keep in mind, results can vary depending on your skin type, activity level, and surrounding conditions [1][2]. Stick to the placement tips shared earlier to ensure the best performance.
