Dexcom Sensor Video - Sort Of.

I've had several emails about how to apply the Dexcom sensor (watch the video), how big is it (like two quarters side-by-side), does it hurt (not usually), does it automatically give insulin (no - that would mean it's a pancreas), does it need to be fed or watered (no), can it fly (yes - when I throw it), do I like it (yes).

I wanted to do an akward little instructional about how to apply a new Dexcom sensor to my lower back, and with Chris's help, I think we captured most of it.  It gets a little shaky in there when we're clipping in the transmitter to the sensor housing, but you get the gist.  Hopefully.  :)

As far as placement goes, I've worn it on the back of my arm, on my abdomen, and on my lower back.  My main issue is keeping that sucker STUCK to me for the full duration.  For those of you wearing a Dexcom, where are you sticking your sensors?  Any tips on new places?  

(Please forgive me for talking so damn fast on that video.  I forget that not everyone communicates at the same foolish warp speed as me.  I need to take a breath!) 


Great video! I would have liked to see the part where you disconnect the plunger thingy from the rest of it a little slower. I know that part is often the hardest for people to do the first time because it's not easy to see how it comes off. Also, thanks for the tip on the Skin-Tac. I may have to try that out.

This was great, Kerri!

I've tried to describe what this might be like to Joseph (based on what I've read)-- so helpful to be able to show him this video.


thank you kerri!
i so needed this! as you know i've been trying to make this big decision, and this is the one that did it for me!

love ya!

I use IV prep to clean the area first and it also has an adhesive to help it stick better. After I have the Dexcom in place I use Smith & Nephew OpSite Flexifix tape http://www.amazon.com/Smith-Nephew-OpSite-Flexifix-Transparent/dp/B001CYEUKO/ref=sr_1_3?ie=UTF8&qid=1227627889&sr=8-3 it comes on a roll which I like because you can cut strips the exact size needed. I put a long strip of tape on each side of the Dexcom and it stays there until I pull it off 7-10 days later. The Opsite tape is the strongest medical tape I've ever uses and it really stays put!

The only places I've worn my Dexcom is my stomach and my arms. I like my arms the best, it out of the way.

Nice video Kerri.

I usually straighten out the fabric part before I remove the backing. That helps me stick it on better. I also leave the extra piece of plastic in place until it's stuck on me.

When I place it, I'm careful to push the top part or the fabric in place first, because there are always folds. If the folds are below the sensor I've got less issues with water getting under there in the shower and loosening it up.

I also press the fabric in place really hard before pushing in the plunger, I want that thing to bond to me as much as possible.

Don't forget to clean the back of the transmitter from time to time.

Right now I'm getting 10-12 days per sensor on average. Generally it falls off before it expires.

Very cool. I was wondering how that worked.

great video!! I'm always interested to see the sizes of these things - and so seeing them in your hands gives a much better idea than just seeing a picture.

Thanks for the video - I think . . . no, I HOPE a CGMS is in my very near future. It was good to see an insertion in action. How big is the needle though? I keep hearing they are HUGE. I'm hoping they are smaller than I picture them.

I second the OpSite Flexifix tape~ Works wonders!!

Thank god for you and people like you . You are so helpfull and kind to post this on your blog . God I shudder to think what we would have to do without you . That is okay I talk fast too and everyone tells me to slow down when I am talking . LOL!!!

Thanks for this great video! I just started the insurance paperwork for a Dexcom CGMS and I'm getting a little nervous. You make it look so simple!

You know you are a real vlogger when you do a voiceover for your own posts! :)

For some reason, I'd imagined a much more complicated process.

Also? You're not talking fast, but then, I'm from the same neck of the woods as you and I think we all must talk like that up here.

I have found one of the most successful sites is my hip.

I use Tegaderms to reinforce the site after I apply the sensor. There was a discussion about it on Tudiabetes and I uploaded some photos here.

The nice thing is that if the Tegaderm looses it's grip, usually after about 7 days, you can gently peel it off the Dexcom site and then reapply a fresh Tegaderm and get more life from the site.

Hey Kerri-
I like! I just put a sensor on the back of my arm for the first time and it seems to be working really well! It might even work there when I am in the race car. If you get skin irritation- try using an Azmacort inhaler as a spray barrier- it really has helped me.


Very cool video. I had no idea how these things were attached and now I know. Thanks for showing us how to do it, Kerri! And, as someone who took insulin injections for nearly 30 years, who does warching you push that plunger kind of creep me out?

Wow - I guess I had always assumed that the sensor insertion process was the same for the Minimed CGMS and for the Dexcom. Wrong! The Dexcom insertion looks waaay easier than the scary evil Minimed one that I have to get drunk before using. Hmm. Take a lesson, Minimed!

This was excellent, great job! I'm about to get the dexcom next week, so I'm very excited. Thanks for the video

Good job Kerri, thanks!

Hint on the excess skin tac.. Let the site dry a bit. then take a little bit of baby powder (Or gold bond)..and lightly rub it around the skin (trying to avoid the sensor area... the powder sticks to the skintac, instead of your shirt .. Mostly. But its an improvement ;)

NOOO! Do not remove the plastic tab 1st, remove it last after everything is in place on your skin!
