For users of a Dexcom Continuous Glucose Monitoring ("CGM") device

Just as a reminder with the recent release of the new Dexcom G4 to the US market--it is NOT okay to post about previous models or older sensors as being 'for sale' on this site.

It is a violation of the Terms of Use because it is a prescription device, and any such efforts will unfortunately be removed.

We encourage you to donate supplies to non-profits such as the Charles Ray III Diabetes Association (http://www.cr3diabetes.org), which accepts unexpired glucometer and insulin pump supplies, or alternatively you may talk to your physician's office or other local medical group to discuss donating them to those in need of assistance.

Thank you all for kindly refraining from this activity.

The purpose of the Bard Protective Barrier Film is to make the Tegaderm adhere better? This is quite the layer sandwich...Bard, Tegaderm, then sensor. Are you using this to be able to swim or otherwise engage in activities that push the adhesives to their limit, or just to be able to get many weeks during normal use?

Comment by Tapestry on December 27, 2014 at 4:29am

I first use Bard Protective Barrier Film (740013), wiping the entire area where the Tegaderm will be placed. The link you showed looks like the same one I use, which is 3M Tegaderm Film 1626W. It all adheres to the skin very nicely. Then yes, I inject the sensor directly through the Tegaderm. I have read where a lot of people will cut a hole in the center, but I have never had to do that and my Dex works like a charm!

You're using the Tegaderm that has a clear window in the middle (http://www.amazon.com/3M-Tegaderm-Transparent-Film-Dressing/dp/B000...)? And you're sticking your Dexcom on top of that, with the filament puncturing the window and into you?

Comment by Tapestry on December 26, 2014 at 7:30pm

I have only used Tegaderm; yes, the transparent dressing. I generally place the Dex on my belly; I've had it on my upper thigh, but prefer my belly. I used to use the Tegaderm over the entire Dex setup (even though it wasn't recommended to place it over the transmitter, I did to stop the ???, which it did, lol). I did this for a year or so. But, after a post from another user, I tried it with the Tegaderm under everything and it has worked like a charm; I like it much better. They advised that I place the sensor so it is vertical, rather than horizontal. I've done it this way now for a two or three months. As for the pool, yes, it stays on, perfectly; I have had great success, I rarely have had it curl up; I can only recall one time, in the past 18 months or so that I've used the Dex, that that has happened and it was time for me to change the sensor anyway. I too use a 4" by 4 3/4" pre-cut piece of Tegaderm. It is quite thin and I don't need to cut a hole in it before I place/insert the sensor.

I don't use my abdomen for sensors. My current sensor is on my right breast. But that is a new site for me, usually I use the back of my arms or my thighs. I cut a square of 4" opsite, cut out a hole for the transmitter, place it over the sensor and it sticks for 3 weeks. If it starts to peel up, I trim the part that is peeling and replace with another strip of tape. It is transparent, waterproof, breathable, and helps secure the sensor. The 2" stuff is just too short for my use but I'm sure some people use it to good effect.

Comment by niccolo on December 26, 2014 at 1:28pm

I assume you're referring to Tegaderm transparent dressing with the window in it? Does that really stay on and sealed in the pool? The issue I have with dressings is that there's a lot of abdomen movement during swimming, and the stuff I've tried so far just doesn't stretch enough to stay on for long.

Comment by niccolo on December 26, 2014 at 1:26pm

Does the Opsite Flexifix go on the skin, with the sensor on top, or over the sensor?

Comment by Laura on December 26, 2014 at 1:18pm

Do you really need a 4 inch one? Seems big.

Comment by longsands on December 26, 2014 at 1:17pm

With the opsite, do you cut a hole for the transmitter?

Comment by Tapestry on December 26, 2014 at 1:13pm

I use Tegaderm and it works great. I've gone a month, before I had to change it. Today is day 21 and it is working great, often times spot-on when I calibrate it. I know it's time to change when I get ??? or when it is too far off from calibration.
