Repeated Dexcom G6 failures


#42

Hi, I have 4 daughters 22, 17, 13, & 8 using G6 for about 2-4 months. The three older girls connect BT using new iphones; 1-X, 2 7s. But the 8 year old using the ipod + G6 display device goes through more sensors than the older girls. she will get a sensor failure message w/ the prompt to warm up for 3 hours, but I have noticed that it comes back live sooner. The last one I called in had a strange error about re-calibration or re-warm up and the CS person said that was not even an error on the G6 (new call center in Indiana).

The 8 year old also loses and establishes communication on both devices several times a day and I believe that may cause more of a power drain on the transmitter. This is not a problem with the older girls because their phones are always in the transmitters vicinity.

The other issue is a high failure of the sensor coming out of the body before 10 days.
I was told that they are opening new call centers and ramping up production, but I spoke to them late last week to replace several sensors and a failed transmitter. They have a 10 day delay on sensors because of the production back log. I can only get a replacement order for 3 sensors at a time and that call takes 1 plus hour. I am lucky because that is 4x3 not 1x3. One CS person told me to call in every 2 weeks, but I plan to escalate it because it is crazy.

I did speak with a CS software person and I know they have the capability to analyze sensor and transmitter performance. I am not sure how they troubleshoot with you, but I have them go in and look at the account that is having problems.

What are you using when he is at school to transmit to the cloud? the Dexcom apps or what is this openAPS? I am looking to be able to get real-time G6 data to generate IFTTT triggers when BS is low, like large siren that sounds in the 22 year old’s apartment to wake them up. It does not look like the FDA is allowing Dexcom to make the individual’s BS reading available real-time and they are forcing them to do a 3+ hour delay.

Good Luck,
Steve.

We just called them as Eric has had a number fall off due to adhesive issues – which we’ve never had with the G5 or the G4. I’ve also tried site prep wipes, alcohol, showering, not showering – the adhesive just sucks.

They are shipping us some free site covers as we speak. So call them, and ask them about it! And I really hope you get this sorted out. I’m so sorry, I know what an important the Dexcom is to your family.

Also, I am recovering from foot surgery, and at some point while it was infected – the ER doc wanted me to keep it dry. The solution that I found best was to put my foot in a plastic bag with a paper towel underneath and use Coban, that stretchy adhesive stuff (they have it at the dollar store) that labs use to cover your blood draw site, around the plastic bag a few times. I thought that might work with plastic wrap for your showering excitement!

Holy cow @stevekrueger I am so sorry that you’re having this problem at scale! And also fascinated, because you have a lot of data points in your house. :wink: I think your plan to escalate and keep on top of them is wise!

Also,welcome to FUD! We like data here! There’s many parents of T1D kids here, and lots of acquired knowledge about T1 in general. I’m glad you found your way here!

Consider adding your info to the welcome post: Welcome, introduce yourself here!

My partner is the diabetic in our house and he’s 39, and uses the G6. He’s had some issues with longevity of the sensors, but our life is a tad nuts right now, so diabetes has taken a bit of a back burner. Dexcom had said that they will send replacement sensors when we’ve called, but we haven’t really been tracking how quickly they failed lately or how quickly they arrive.

I hope that they come up with a solution for all of us soon, because having the Dexcom certainly is handy. I have noticed that the Dexcom share option also goes off-line fairly frequently, and I have to contact Eric to get him to share the data again.

Again, welcome, and thanks for joining us!! We look forward to learning from your family and hopefully FUD can help you too. :grinning:

Hi there. We are in the 2nd month of G6 with our 5 year old and the first month went well. Now we are seeing dropouts and readings that are not consistent with the glucometer for the 7 to 10 day range. We were calibrating constantly and by Halloween it was totally unreliable. We let it go and relied on the glucometer checks as though she wasn’t wearing her dexcom until the sensor stopped on day 10 in order to fully document the issues for when we talk with her endocrinologist and the dexcom folks. The adhesive was never an issue and stayed put because we trim our Simpatch slightly upon application and then cover it with a new one at the halfway point so there’s a new edge when the edges on the first patch start to peel.

we’ve gone back to the G5 because we’ve been having so many problems. I wonder if it has to do with geometry. Most of the people I’ve heard having problems are wee little ones; maybe there’s just something about the sensor that is more finicky when there’s not as much tissue to insert into.

@TiaG, sensor problems like that are a pain. I have also been having sensor problems with the G5 for about 6 months: before, I could make them last 10-14 days, but in the past 6 months I have been having a hard time getting them to last just 7 days: we have to ask for a lot of replacements. This is weird because I am not any thinner than I was (although I don’t have a lot of fat).

What I do to avoid problems: I look for the perfect spot every time: as fat as possible. I really pay a lot of attention to exactly where the sensor will go. It helps me not have as many failures. But I still have frequent failures, just not as many as I did for a while. Maybe that can help Samson a little?

I worry about your problem for myself too: if I can’t keep my sensor going for 7 days everytime I think it will be harder for me to keep the G6 going for 10 days. But right now we are stuck with the G5 anyway because we are far from home for many months still. So I hope you will figure out how to deal with it before we get back to the US :smile:

I’ve had similar issues with the G6, especially after doing exceptionally sweaty exercise or having the transmitter/sensor combo get wet repeatedly. It doesn’t seem to always immediately effect the readings, but it absolutely seems to be directly correlated to early sensor failure for me. One thing I’ve started trying is using compressed air to blow into the gaps between the sensor and transmitter after a shower, but I haven’t noticed much of a difference yet on overall sensor life, but it has prevented losing readings immediately after (still only getting about 7-8 days on a sensor vs 10+ with limited immersion and exercise). I’m thinking about trying throwing a tegaderm over the top of a sensor (and the simpatch) next time to see what happens.
