SoCal Road Trip
my new friend Dexcom and I thoroughly enjoyed our first Southern
California road trip together. My girlfriend and I drove to
Orange County to visit my sister, went to Disneyland, and
finished up at the Coachella Music Festival in Indio, CA.
Dexcom worked well and gave me useful information throughout
the trip. At Disneyland, it was nice to pull out the receiver,
while in line for rides, and quickly get an idea of my BG
levels. I also enjoyed watching my BG trend up and down, like
a rollercoaster, after eating many sweet treats including
an ice cream sandwich, chocolate churro, and Dole whip (yum).
lineup was great and included many of my favorite bands including
Kanye West, Franz Ferdinand, Daft Punk, and Depeche Mode.
Again, it was very convenient to look at my Dexcom between
music sets to gauge my BG values. Thanks to Dexcom, I learned
that during long road trips, my BG's tend to rise and stay
above 240. It could be from the lack of exercise, stress of
traffic, or excitement of the trip. Next road trip, I should
increase my basal a few percentage points to maintain lower
Troubleshooting Tips from Customer Service
I talked with the director of Dexcom clinical services to
discuss my issues with the system. He said that other users
have reported similar issues, they are working to remedy to
these quirks, but gave me some quick fixes for now. Here's
what I found out:
Calibration Requests: when the Ultra meter memory starts
to build up, the Dexcom receiver has trouble calibrating.
The quick fix is to do the Ultra finger stick test, wait 10
to 15 minutes, and then calibrate the receiver. The receiver
will use the correct time stamped BG value from the Ultra
and adjust the sensor readings accordingly. I tried the fix,
it works well, and I haven't experienced the issue since.
"HIGH Above 400" Readings During Exercise: these
occur when the transmitter/sensor connection comes in contact
with water or very high humidity levels. Once the water evaporates,
the error goes away and the sensor works normally. This error
is called a "shower spike" because it usually happens
after a shower or swimming. He added that I should clean the
transmitter electrodes with alcohol after every sensor change
to ensure a good connection. My first experience with this
error happened while I was running the Lion Street steps and
sweating profusely. The sweat must have hit the sensor/transmitter
connection and caused a short. My second experience was after
swimming and showering with the shower patch. After wearing
the shower patch for over an hour combined with the increased
activity must have caused the watertight shower patch environment
to become very humid and cause a short. Now I know what causes
this error and to be aware of it.
Rate Monitor Interference: they are investigating the
issue, but haven't been able to replicate the interference
in the lab.
they are working on the software and it should be out soon.
very nice speaking with the clinical director of Dexcom about
my issues with the system. He was very friendly and offered
to keep in touch to check on the status of my issues and questions.
for my sensor comparison is taking much longer than I had
anticipated. There is so much info I plan to deliver my report
in a few different segments. I should have the first report
complete next week.
not work for nor am I compensated by Dexcom in any way. I'm
writing this story because I think continuous glucose technology
is interesting and exciting. Also, I am not a health care
professional and do not give medical advice. I will share
my experiences, but please check with your health care team
before making any changes to your diabetes or health management.
