Issues with Dexcom G5 performance

we are getting breaks in data, which SEEM to actually be when we are driving around, K has been to several basketball games this week requiring bus rides through no internet signal regions. BUT that shouldn’t make a difference, right? Because it’s connecting with BLUETOOTH, to her PHONE. So I can’t explain that. It’s pretty solid at home and at school for her. She did have a low last night, 55 alarm work me up and I gave her juice, and it resolved up to 90, then dropped back to 55 again at 600 this morning. After juice we did a fingerstick and it was 105, SPOT on with the dex, so we haven’t seemed to have inaccurate data ( yet) Keep me posted on progress and thoughts!

us too, but it is tolerable

I can give a solid maybe to this, K likes to connect to bluetooth for speakers and other things, so we are going to see, definitely there are some drops in the bluetooth, we just haven’t correlated whether that is related to a second blue toothed device or not. So far she also bluetooth’s to our car for calls AND a variety of speakers for music! Anyone else?

good points all the regular stuff can still go wrong!

so this could happen in a tummy sleeper? My 15 year old is a tummy sleeper, we’ll look for this.

Apparently this Dexcom G5 performance thread has caught the attention of Dexcom’s “Engineering Manager iOS Apps”. He has contacted me and I am to speak with him about the irregularities I have found. I am glad that Dexcom is showing interest in fixing these anomalies and confirms my suspicion that they actually do monitor this site for feedback. Hopefully we can sort out this problem.

I’ve always suspected that the various device companies keep an eye on our conversations but I don’t often read confirmation of this. I’m glad Dexcom is getting a good report from you. I’ve admired how they appear to be well connected with their users.

I think too often these companies get the counsel of a select few PWDs and then over generalize the small group experience to the larger population. When I come across a feature or lack of a feature in a device I think to myself, “Was a 24/7/365 PWD even involved with this decision?”

I trust Dexcom will fix your problem while it continues to iterate its models and designs at a modern pace.

Now… WHERE’s THE ANDROID version of Share?? :smile:

(been getting by with xDrip/Nightwatch – even happy with them, to be honest :smiling_imp: )

I was on the phone with Dexcom yesterday. I asked about the Dexcom G6 timeline. While I didn’t expect any hard info, she did say that the Dex Andoid version of Share was now project #1.

I didn’t know you were using the xDrip/NightScout system. Are you using a Pebble watch to monitor your BGs?

This exact same thing happened to me. The story is pretty “Fun.”

About a month ago my girlfriend is in NYC on business so I’m alone at home. I call her and say goodnight then fall asleep watching football.

A few hours later I wake up to both of my ipads and my phone going off, 27 missed calls, and someone banging on my door.

Apparently my sensor had malfunctioned (just like yours did) which showed my blood sugar dropping below 40mg/dl (apparently below 40 it just says “Low”). My girlfriend and mother (who lives about 45 minutes away) both have the Dexcom share app so they received the low notifications.

Unfortunately, since I had fallen asleep with the TV on, I didn’t hear the phone calls when they checked up on me. They eventually started panicking and called 911.

The people banging on my door were four paramedics wheeling a gurney and my girlfriend had already given them permission to break our door down. In addition, my mom and dad were already in the car for 30 minutes driving to my house.

Long story short, my blood sugar was somewhere in the 95 mg/dl range and I’m extremely well regulated (honeymooner) so it likely never even dropped below 80. I called Dexcom the next day (they know the full story too) who shipped me out another sensor.

Torq: Bummer that your Dexcom provided a false-low reading. But it must be nice to know that the peeps looking out for you take this job seriously!

No - I have an Asus smartwatch (AndroidWare) that gets the Nightwatch watch face. Works well.

I had that happen with a sensor after our first snow storm. I attributed it to the fact that I drove 20 hours through the storm and thought that since my sensors were packed in the back of the car, they might have been subjected to temperatures that were too cold. The sensor was also a bit aged. No idea, for sure, what caused it.

I have been using the G5 since October 2015 - and it has made my brittle diabetes much easier to manage - even after 40 years or learning without. But the experience has not been smooth. I am self funding in the UK and had initial support. After experimenting I find the upper arm is the most reliable. The biggest issue was the transmitter - I kept getting dropouts X’s ??? etc - normally 1.5 hours long - and suspected the transmitter - but the UK support dissagreed - so I continued to get issues until 2 sensor insertions failed - and then 2 hours later a low battery warning after 7 weeks use. They have now replaced the transmitter and all is well. *** The important things to note is the symptoms - (i) Constants drop outs lasting ofter 1.5 hours, (ii) Changes in temperature affecting operation, i.e. sleeping under quilt or excercise and (iii) Sudden stepped changed in blood glucose readings.Even though it has left a bitter taste in my mouth I still choose to continue using the G5 - although feel the UK office need to be more helpful.

Hello all, i am new to the dexcom… got the dexcom g5 mobile. I have been wearing the dexcom for about one week. @day was the 1st time that i changed the patch-glucose “reader”. about 1 hour ago i was busy witha project when all of a sudden my Receiver buzzed and said my sugar level is 12 and with 2 arrows facing straight up(12 is very high).

i then checked with my other glucose tester and my sugar was 8(8 is fine)…

why can this be?.. thanx for all ur help.

Was this a trend, or a sudden change in the dexcom readings? Also, where do you have the dexcom located?

It was a rapid increase… From 8 to 12 in 15 min… But both my other testers said it was round 8

Wow, that explains what my son has been experiencing…reading 75 on Dexcom and finger stick shows 101 or something. Great to know! Now, to try to convince my two-year-old to not to sleep on his belly with his arms underneath him.

I have had these issues too. Low and High. Just remember that Dexcom isn’t testing blood–just the interstitial fluid under the skin. This means that there is not only a delay between BG and Dexcom, but other variables (such as pressure) that can cause weird readings. Not to mention the formula used to calculate the number itself. Also…your BG meter isn’t always 100% accurate, so if your meter tests on the higher end of the error margin and Dexcom lower–then it can seem quite off. Always rely on the BG meter over Dexcom. In my experience, I tend to use Dexcom qualitatively–not quantitatively. That is, I look at trends–not the number itself. Also, be sure to try to calibrate when your BG is the most stable and in a good range.

Hope this is somewhat helpful.

I somehow hit one when I rode for the first time after getting my CGM. I’m only at 6 weeks in and last weekend was nice enough to ride. Managed to rip out my infusion set too. Definitely need to be more aware of how I’m carrying my equipment etc. and how my safety vest fits against where my sites are.
