Has anyone else had difficulty getting used to using a CGM? My doctors office has a Dexcom 7 and partners with the local sales rep to let patients try it out. I’m on day 6 of 10 if the sensor will last that long. With this arrangement I have only the sensor/receiver, no software to download data and see what that provides. We will do a download when I return it.
I’m a little overwhelmed about what to do with all this information. Yesterday (day 5) was really the first day where I’d have an urge to look at it and I was able to resist because looking at it too often isn’t the point. I know the point is to use it as a trend tool.
At this point I would say I’m a little disappointed that it works they way they said it would, meaning that I still need to use a meter. LOL! Of course that’s not fair at all!
I’m really just looking for tips and advice on how to make the CGM experience more rewarding. How did you shift from many years of pre and post meal testing to this? Is the key to just get past the newness and only look at it when I would do a finger stick?
#1 - Generally the max difference from a finger stick seems to be about 25-30 points. If a meter is only accurate to 20% and the CGM is 20-30 points off of that, this doesn’t give my technical side great confidence.
#2 - The range is rated at 5 feet, but mine goes out of range several times a day while it’s in my pocket or on the desk in front of me. Maybe not a big deal and related to looking at it obsessively.
#3 - Seems larger than it needs to be. Feels and sounds kind of hollow.
#4 - It seems to read low before I feel low (good to err on the side of safety) but then it also stays low after I correct and feel okay. Does you body pull glucose out of your interstitial fluid during lows?
#5 - If I take novolog 15-30 min prior to a meal the graph remains nearly flat for 2 hours post meal and then begins rising.
#6 - Be accurate and reliable enough to replace finger sticks.
#7 - Alarm not loud enough to wake me up.
#8 - If it can’t replace finger sticks, put a meter inside the receiver so I don’t have to carry two pieces of stuff. See hollow comment above, use that extra space for one more microchip.
#9 - Make range about 20 feet so I’m not always tethered to this thing! It sometimes drops out while on my night stand, and I’d like to be able to walk around a room without concern of Dexcom range.
#10 - Alarm has no snooze function - alarm me again in 30 minutes if still high or low.
#11 - Ability to enter times & values for insulin & food and represent them on the graph. I’m a one touch ultra smart user and really miss this. Also put a time label on the horizontial axis of the graph. It’s blank which is just stupid!
