Default Dexcom sensor duration

Well, on my first sensor I got to day 12 before it started giving me dots and ???s. I am happy with that. I found changing it out easy and can see I will soon be doing it without the directions in front of me.

Some report as much as a month, but I seem lucky to get 7 days. I think it may have to do with glucose swings, especially highs with which Dexcom serms less friendly. The techs tell me it's especially tuned for lows.

Right now, I'm particularly interested in transmitter battery life - something you're many months away from. My first got a year, the second about seven months. The entire little gray transmitter must be replaced at a retail cost of about $500 US. You'll get a low-battery warning on the receiver when it's time.

They're warranteed for six months and insurance rates vary. The typically friendly tech is currently checking to see how much I'll have to pay out-of pocket, perhaps as much as 50%, in my case. Ouch!

No advice forthcoming as to why the variation. Similar affair for the black receiver. I managed to break my first one having failed to keep it in it's leather case.

Naturally, we quickly become addicted to these things!

How are you doing with the high/low warnings?

My first transmitter for the Dexcom G4 lasted 7 months to the day. My current transmitter is approaching the 6 month mark. Since Medicare does not pay one red dime for CGMs I expect I will have to order a new transmitter soon. Someone told me, and I can't say this is 100% true, that IF you order a new transmitter before the 6 month guarantee time is up - the price goes from $599 to $199.

Default high and low alerts

yes, I am loving the high and low alerts. I set my own preference at 4.2 so that I can cut off a real hypo before it happens. I have set my high at 10. I wish I could lower the high altert but not yet. I am seeing lower pre meal levels because of the trend arrows which stop me taking unnecessary snacks. This has led me to a little trouble with pre meal bolus timing but I am getting there. I am just loving this.

Could be. Dexcom seems to have a pretty refined sensibility about warranty periods. My last chat with them was sufficiently complex that I can't recall. I wonder if Medicare could be convinced to change their mind?

I almost never turn my high alert on. Once I'm over 200 or so, it'll always take 1-2 hours for it to go down and I don't see any reason to listen to the alerts all that time (I could just turn it off then, of course).

I've lost track of the number of times the low alert has saved me from real trouble!
